What is Zero-Copy in Java?

Zero-Copy is a technique that allows data to move between storage and network devices without needing to copy it into the application layer. In traditional I/O methods, you deal with several context switches and memory copies, but Zero-Copy cuts down on that, making things faster. This approach is super helpful for high-performance applications like file servers or video streaming services.

How Zero-Copy Works Internally

To get a grip on Zero-Copy in Java, you need to understand how the Java NIO (New Input/Output) package operates. It lets data flow straight from a file channel to a socket channel through methods like transferTo() and transferFrom(). This avoids using the Java heap and saves CPU cycles, which is really useful for anyone taking a Java Full Stack Developer training Course in Coimbatore .

Benefits of Using Zero-Copy

Some of the main benefits are less CPU usage, reduced latency, and better throughput. When applications need to transfer large files, they can do it more smoothly. This is especially relevant in enterprise-level development, which is a big part of the Java Full Stack Developer Course in Coimbatore. Developers learn how to improve server-client communication using features like Zero-Copy.

Use Cases in the Real World

Zero-Copy is popular in web servers, file servers, and video streaming platforms. Companies that need fast data handling tend to use this method. Students in Java Training in Coimbatore can try out Zero-Copy in lab sessions or projects related to file transfers and socket programming.

 Zero-Copy vs Traditional I/O

With traditional I/O, data gets copied several times—from disk to kernel buffer, then to user space, and finally to the socket buffer. Zero-Copy skips these extra steps. Understanding this difference is key for anyone learning about performance optimization in server-side apps.

 Java NIO and Its Importance

Java NIO was introduced to support scalable and non-blocking I/O tasks. It gives you the tools to implement Zero-Copy. In a Java Course in Coimbatore, you'll learn how NIO helps create fast and efficient applications, an important skill in the Java world.

 Challenges and Limitations

Even though Zero-Copy enhances performance, it’s not the best choice for every situation. It's mainly useful for large file transfers rather than small bits of data. Also, debugging can get tricky because there’s less access at the application level. Students in the Java Full Stack Developer Course learn how to wisely decide when to use Zero-Copy.

 Industry Demand and Career Impact

Knowing about Zero-Copy in Java can help a developer stand out, especially in roles that require high-performance application development. Many tech companies are on the lookout for skills in this area. For those in Java Training in Coimbatore, mastering these topics can lead to great job opportunities in backend and systems development.

Tools and Libraries Supporting Zero-Copy

Besides Java NIO, other frameworks like Netty also support Zero-Copy. These tools are often covered in advanced modules of a Java Course in Coimbatore. Learners can use these libraries to build scalable, high-performance applications, especially for real-time data tasks.

 Conclusion: Master Zero-Copy with the Right Training

So, Zero-Copy in Java is a handy I/O method that's key for modern Java applications. To really get the hang of it, professional training is a must.

hey quick question what part of the botanical garden do you like the most :3

That is a very good question my friend bestie beloved mutual Leon Ward-Leon, and you have activated my yap card.

You see the garden changes with the seasons, it‘s a living place after all, and while there are a few evergreen places their position still changes based on if some of the other spots are blooming or not and such. For example!

The cherry tree is absolutely gorgeous in spring (regrettably I got no images of it this year. Waugh. Fake fan. I will atone with my life. Dishonor.) during the like. Singular week that it blooms, but is nothing spectacular the other times of year.

The Flower beds are also amazing and less seasonal, but still restricted to Spring/Summer/Early Fall

Amazing. Breathtaking. Show stopping. But it’s not all the flowerbeds have to give.

They switch it up to a summer configuration. Which is also amazingshowstoppinggongeous.

There’s also the food garden which is real nice in summer when they’re mature. Goidneff gravious there’s canbage. And Bean. And poompakin. Fbasinating.

Anyways the version of Tumblr I have on phone won’t let me attach more images so intermission time. There will be more. (Threat)

Spring Boot Interview Questions: Prepare for Success

Spring Boot has become one of the most popular frameworks in the Java ecosystem, streamlining robust and scalable web application development. Whether you’re a seasoned developer or just getting started, acing a Spring Boot interview can be a significant milestone in your career. To help you prepare effectively, here are the latest Spring Boot interview questions that will test your knowledge and give you a deeper understanding of how the framework works. These questions will be beneficial if you're pursuing a Spring Boot Certification Training Course at eMexo Technologies, in Electronic City Bangalore.

1. What is Spring Boot, and how is it different from Spring Framework?

This is a fundamental question that often appears in Spring Boot interviews. Spring Boot is an extension of the Spring Framework to simplify the development process. It eliminates the need for extensive XML configuration and provides default configurations to facilitate rapid application development. Spring Framework requires developers to configure components manually, while Spring Boot auto-configures them.

By understanding this, you can highlight how Spring Boot training in Electronic City Bangalore at eMexo Technologies helps developers focus more on writing business logic rather than dealing with complex configurations.

2. What are the main features of Spring Boot?

Spring Boot stands out due to several features:

Auto-Configuration: Automatically configures your application based on the libraries on the classpath.

Embedded Servers: It allows the deployment of web applications on embedded servers like Tomcat, Jetty, and Undertow.

Spring Boot Starters: Pre-configured templates that simplify dependency management.

Spring Boot CLI: A command-line interface that allows you to develop Spring applications quickly.

Actuator: Monitors and manages application performance.

These features make Spring Boot an attractive option for developers, which is why the best Spring Boot training institute in Electronic City Bangalore emphasizes hands-on experience with these functionalities.

3. What is the role of @SpringBootApplication in Spring Boot?

The @SpringBootApplication annotation is a core part of Spring Boot, often referred to as the ‘meta-annotation.’ It is a combination of three annotations:

@Configuration: Marks the class as a configuration class for Spring Beans.

@EnableAutoConfiguration: Enables Spring Boot’s auto-configuration feature.

@ComponentScan: Scans the components within the specified package.

This annotation is crucial to understanding Spring Boot’s internal architecture and its ability to simplify configuration.

4. What is Spring Boot Starter, and how is it useful?

A Spring Boot Starter is a set of pre-configured dependencies that simplify the inclusion of libraries in your project. For instance, spring-boot-starter-web includes everything you need for web development, like Spring MVC, embedded Tomcat, and validation support.

Starters save a lot of time, as they eliminate the need to find and include individual dependencies manually. When studying at eMexo Technologies, you’ll get an in-depth look at the variety of Spring Boot Starters available and their importance in building scalable applications.

5. What is a Spring Boot Actuator, and how is it used?

Spring Boot Actuator provides production-ready features to help monitor and manage your Spring Boot application. It offers a wide array of tools like health checks, metrics, and auditing endpoints. The actuator allows you to easily monitor application performance, which is a crucial aspect of microservices-based applications.

6. What are Microservices, and how does Spring Boot help in building them?

Microservices are small, independent services that work together in a larger application. Each service is responsible for a specific business functionality and can be developed, deployed, and maintained independently. Spring Boot simplifies the development of microservices by providing tools like Spring Cloud and Spring Boot Actuator.

7. How does Spring Boot handle dependency injection?

Dependency Injection (DI) is a key feature of the Spring Framework, and Spring Boot uses it to manage object creation and relationships between objects automatically. In Spring Boot, DI is usually handled through annotations like @Autowired, @Component, and @Service.

8. How can you configure a Spring Boot application?

Spring Boot applications can be configured in multiple ways:

application.properties or application.yml files.

Using the @Configuration classes.

Via command-line arguments.

Environment variables.

9. What are profiles in Spring Boot, and how are they used?

Profiles in Spring Boot allow developers to create different configurations for different environments. For example, you can have one profile for development, one for testing, and one for production. You can specify which profile to use by setting it in the application.properties file or as a command-line argument.

10. What are the limitations of Spring Boot?

Despite its many benefits, Spring Boot has some limitations:

Lack of control over auto-configuration can sometimes lead to unexpected behaviors.

Increased memory usage due to embedded servers.

Limited flexibility in large-scale applications that require extensive custom configuration.

Addressing these limitations demonstrates that you have a well-rounded understanding of the framework and can make informed decisions about when and where to use it.

11. How does Spring Boot handle security?

Spring Boot simplifies security through Spring Security, which can be easily integrated into your application. By adding the spring-boot-starter-security dependency, you can configure authentication and authorization in a few lines of code. You can also customize login, registration, and session management features.

12. What is the role of the Spring Initializr in Spring Boot?

The Spring Initializr is an online tool used to generate Spring Boot projects. It allows developers to choose the dependencies and configuration options before downloading the skeleton code. This tool speeds up the initial setup phase, saving time and effort.

In conclusion, being well-prepared for Spring Boot interviews is crucial, especially in a competitive job market. Whether you're taking a Spring Boot course in Electronic City Bangalore or aiming for Spring Boot Certification Training, knowing these key concepts will give you the edge you need. At eMexo Technologies, you’ll receive hands-on training, not just theory, preparing you to answer interview questions and excel in your career confidently.

Ch. 68: Do You Think You Did It?

SUNDAY - WINTER 28

One year. He’d made it one year in Stardew Valley. 

The Achilles of yesteryear would never have anticipated this—hell, he had planned to drop in, clean up the property, hand it off to a realtor, and get on out of there before the Summer tourists could even lay down their towels on a beach he’d definitely never envisaged himself ever visiting. Badabing Badaboom. 

But he had stayed. Why? Why was he here? Why was he still here in Stardew Valley after all this time? 

A number of things. Who knows, does it matter? Achilles thought idly to himself as he watered the crocus.

No, it didn’t particularly matter, but he always loved a clear answer all the same. 

Because you needed it. Because it had something to give you. Something to teach you. 

And now… he wasn’t sure if he’d ever leave. He would travel, of course—he knew Shane would keep the farm well under control—hell, that was something, the Achilles of yesteryear would never have helped manage a farm. But Stardew Valley would always be a home. 

Keep your mind and ears open. That’s what Emily had once said to him—reassuring words after a rather foul fortune. Some interesting things might just take root. 

How much he had gained. How much he had let go. Would he ever be truly content? Perhaps, perhaps not. But he would try, a day at a time. 

Achilles glanced up at the small, faded portrait of two root vegetables that he had greeted him the first time he’d stepped foot in the farmhouse. He had kept it in its place on the wall, though he had switched out the ratty sofas below it for something more modern long ago. Next to it now hung the photo Alex had gifted him for Winter Star. They looked a little strange together. He really ought to hire an interior designer. 

There were real things he ought to be doing right now, but he allowed himself the grace to continue his leisurely stroll down memory lane and meandered over to the bedroom where a typewriter now sat gleaming atop his desk, out of its box, alongside several scattered binder-clipped piles of pages and half-filled mugs of tea. 

But he made his way past this clutter, instead searching for something in his nightstand, a letter he had only half-remembered keeping. He had just located the envelope underneath a book of crosswords when he was interrupted by Alex bounding through the front door, fresh from his morning training. 

“Weren’t you supposed to be cleaning?” he asked by way of greeting, peeking his head through the bedroom door as Voltaire pattered merrily across the floorboards to join him. 

“Ha.” Achilles set the envelope back on the nightstand and picked up a pill bottle, giving it a silent shake. “Well perfect timing for you then, isn’t it? Here.” He tossed the empty bottle across the room, which Alex caught with one hand before retreating, all the while shaking his head in dismay, to the kitchen for the recycling bin. 

Achilles’ parents were finally paying Stardew Valley a visit. Neither had seen the town in twenty some years, but Apolline and Perry were due to arrive in three hours for lunch and would be staying at the farmhouse for the next week, just in time to bare witness to the Spring planting he and Shane were already gearing themselves up for. 

Strawberries and kale, green beans and potatoes, garlic and cauliflower; Shane had been eager to get a jumpstart on the season, and so the two had gone over the plans the day before, plotting out the various patches on Achilles’ obviously to-scale diagram, analyzing the best configurations for the scarecrows and sprinklers.

At Achilles’ insistence, they had reserved one small area down by the pond for the tulips he knew Evelyn loved and another area for leeks. Shane insisted it was a “stupid choice” and “waste of space” due to their low profitability—but Achilles couldn’t help himself. He still wanted to get on George’s good side, at least for Alex’s sake. Progress had been made, for sure—the old man made eye contact with him now—but a biweekly gift of his favorite vegetable could only help speed things along, right?  Especially as their relationship was perhaps taking two steps back this week, for there was limited room at Strawberry Farms with Apolline and Perry’s arrival; and although Achilles had purchased an air mattress for himself, Alex had insisted he spend the next few nights with him instead. 

“I’ll expand this bad boy next year, though,” Achilles had said the day before, slapping the frame of his front door after sharing the problem to a barely-listening Shane. “Add a guest room or two. Probably two, there’s just so much space to expand. Perhaps even a living room, or at the very least, a piano room. I had a Steinway back in Monstera, lovely thing, I should get back into playing… Of course, we’ll have to expand the closet, add another full bathroom. Oh goodness, and of course, we have to have a library! Combine it with an office, perhaps… well, I suppose we’ll be keeping Robin busy, that’s for sure.” 

“You already have a living room,” Shane had grunted, nodding at the couches by the fireplace. 

“Hmm, I think I’d call that more of a family room.” 

“Fuckin’ hell.” 

Achilles had placed an order at the Stardrop for several dishes due to be delivered at noon, but Alex had persuaded him to do at least a little bit of cooking himself to celebrate his parents’ arrival. 

“Nothing better after travel than a home cooked meal!” he’d said, to which Achilles had darkly responded under his breath, “Yeah, yeah, I’d argue that depends on who’s cooking it…”

Alex padded back into the bedroom where Achilles still sat and took a seat by the desk. 

“You nervous?” Achilles asked, turning away from the nightstand to pick up a sweater he’d left on the floor that morning. “If so, you can channel that energy into helping me clean.” 

“Huh. Sucks for you, I’m not nervous.” But Alex joined in nevertheless, returning the books scattered about to their respective places on the shelves. “You know, I’ve been told I’m pretty good with parents.” 

“That doesn’t surprise me at all—”

“Although I’ve never met famous people before—shut up, you don’t count. But you’re the one who keeps telling me how, like, nice your parents are, so I feel like I don’t need to worry, right?” 

“That is true, they are very nice.” 

“How’d they end up with you?” 

But Achilles didn’t take the bait, only shooting Alex a resigned look before saying, “Mysteries of the genetic universe, I suppose. Some of us just turn out worse than our ancestors while some us are… better.” 

There was a second delay before Alex seemed to catch the minor implication behind Achilles’ words. But after a beat, he bit his lip and turned slightly pink, hands fluttering about in search of nothing, before giving a jerky little nod and returning to the desk. In what seemed like a hurried attempt to transition topics, he picked up one of the stacks of typed papers on Achilles’ desk and asked, “Is this your new book?” 

“Mmhm, that’s like… draft 4? Maybe?” 

“Wowiee, so productive! It says ‘green’ on the cover, though—” 

“Yeah, I got in the habit of using colors as a kid because of my dad. Probably thought it made me incredibly cool and unique or something—” 

“Can I read it?” 

“Oh. I mean… it’s not very good. Not yet, at least.” Achilles closed his closet door and walked over to join Alex, who reflexively slipped an arm around his waist. “But I suppose if you really want to…”

“Nauer, it’s ok. I’ll wait until you’re ready.” Alex gently set the pages back down and buried a kiss in Achilles’ hair.  

“It took a bit, but I think I’ve finally come to terms with it. Finally forced my stubborn brain to listen to my stupid ass heart, you could say.” Achilles sighed and looked out the window. The temperature had been rising; the snow had mostly melted away now, revealing, amidst all the mud, the tiniest green shoots all across Achilles’ farm. Weeds, Shane had noted, but signs of life all the same.

Buds were beginning to appear alongside returning songbirds in the fruit trees they had planted. He could hear their whistles, the flutters of their wings among the branches. And the biting wind that had scored his home with creaks and murmurs in the weeks previous had slowed to a tickling breeze. Achilles had even caught sight of a few junimos the previous day, blue and green, bouncing across his land. Spring was coming.

He stepped backwards, leaning into the firm figure of Alex behind him, the touch of his hand on his shoulder, and sighed again. “Adult literature just isn’t for me right now.”

“But that’s okay, right?” 

“Yeah,” he said, turning to meet Alex’s warm, steady gaze. “That’s okay.” 

*****

Alex had manhandled him into preparing a salad (“it’s just cutting, you can even buy pre-peeled pomegranate seeds”) and some shrimp tartlets (“I’ll send you the recipe, it’s not hard”). He himself was baking a focaccia; the first sourdough having been a smashing success, Alex now considered himself something of an up and coming bread connoisseur.

“Scoot ya boot,” he said, giving Achilles’ ass a light tap to step aside as he bent to open the over door. 

“Yes, chef!” 

Alex rolled his eyes good-naturedly, sliding in his bread before straightening up to see Achilles, a pathetic little pout now on his lips, cry, “Help.” 

His nose crinkling, Alex scrutinized the glass bowl between Achilles’ hands. “You don’t need help you dingus, you literally just blend those things together—”

“Um, that is just so rude, you’re supposed to listen, actually, when someone asks for help, instead of bullying them—”

Alex attempted to silence him with a kiss, but Achilles pushed him back with both hands, shouting, “Get away! This is a kitchen, Yoba, have you ever heard of germs? Cross-contamination?” 

“Man, shut up, when the heck have you ever cared about germs, I found a week old bottle of lemonade on your desk…” The bread was in the oven, and Achilles was being, well, Achilles, so Alex decided it’d be best to step away from the chaos and observe from the fridge. “Sometimes I think it’s a little weird, you know.” 

“What is? Wait, don’t talk right now, I’m about to blend.” 

With a rather concerning amount of glee, Achilles gave a little hop before jabbing the “On” switch on the blender Alex had brought over from his own house. The mixture of cream cheese and onions and other various ingredients for which Achilles had painfully perused Pierre’s general store gave a start, and after a minute of rackety churning, he popped open the lid and shot Alex a thumbs up.  

“I was just saying that sometimes I think it’s weird how… not weird it is. I was worried everything would get awkward, since we were, like, just friends first. But I don’t know.” Alex shrugged. “It just never really felt weird. Like I never had to force myself to touch you.” 

Hearing those words, Achilles whipped around, the tail of his new apron smacking the handles of his drawers. “Excuse me?” He jabbed his silicon spoon towards Alex like a fencing foil before returning to his tartlets. “Well, I am so happy for you that you don’t feel like you had to force yourself to touch me—”

“—okay, you know that’s not what I meant—”

“—absolutely disgusting creature from the abyss, was expecting to have to poke it with a ten foot pole—”

Alex rushed forward, and, taking advantage of Achilles’ intense concentration (rather than eyeballing the job, he was carefully scooping out each tartlet’s cream cheese mixture with a measuring spoon), picked him up and dipped him to the floor, ignoring Achilles yelp as he laughed. 

“No! No! The sauce—the sauce!” Achilles cried, flailing his arms before his screams dissolved into laughter as well. 

“All I was saying,” Alex said, returning Achilles upright. “Was that it feels good to touch you. And to kiss you. And to call you my boyfriend. It’s easy.” He handed Achilles back his spoon and pecked him on the cheek. “And this isn’t even considered a sauce, man.” And with that, he smacked the back of Achilles’ head and walked away. 

“I’m suing you for battery.” Achilles waved a fist at Alex’s retreating figure. “Expect the court summons in the mail in one week!” 

*****

A quarter to noon, they returned to the bedroom to change out of their “chores clothes,” as Achilles put it. “Rich people things,” Alex had muttered under his breath. 

“I will say, this part does kind of make me nervous,” Alex said, wriggling into a mustard jumper Emily had helped pick out for him the previous day. “What if your mom thinks I dress bad?” 

“She thinks I dress bad, and she still loves me, it’ll be fine.” Achilles was sticking to all black today, but with the warming of the weather, had exchanged his sweaters for a loose button down and a blazer. “Anyway, she loves plaid—Emily probably knew that—and you look adorable. Like a wee bumblebee.” 

He dodged the hoodie Alex hurled at him. 

“Hey, now what’s this?” Alex was kneeling on the ground, the pale green envelope Achilles had been searching for earlier that morning in his hands.

“Nosy.”

“It fell off the nightstand, I swear— ‘To Achilles.’” To demonstrate his good faith, he handed it to its intended recipient. “You’ve got some secret love letter from Lewis you’re hiding from me?” 

“Oh my god, it really is the same envelope isn’t it, I didn’t even realize—“ Achilles flipped it over and slipped his finger under the flap. “But no, it’s not a love letter from Lewis, if you can believe it. Here, you can read it if you want, it’s actually—“ 

There was a knock on the door. 

*****

Apolline Desrosiers and Perry Robinson had taken a six hour flight across the Ferngill Republic, and a three hour taxi ride down from the nearest airport, and yet, Alex thought he had never seen two people look so… put together, after so much travel. 

“That’s just the first class talking, don’t praise them,” Achilles said over his shoulder as he opened the screen door. “Hello, hello, hello!” 

The rumors were true; on the surface, Achilles looked little like his mother, whose amber eyes and shimmering blonde hair ended in soft curls just below her shoulders. She was a tall woman, nearly as tall as Achilles himself, with a nude manicure, a pair of diamond studs, and an oversized, brown plaid blazer that Alex didn’t think Achilles would ever be caught dead wearing. 

And yet, he could still see a bit of Achilles in her—he shared her athletic build, as well as her sharper features—and there was something familiar about the angle of her eyebrows. Eyebrows that were currently raised high on her forehead, for Apolline was nearly jumping with joy (an impressive feat, given the stilettos) fists bunched in front of her widely-grinning face as she embraced her son with a squeal. 

No one had ever been this happy to see him in the past decade, that was for sure. Although, perhaps that was unfair—Alex had never strayed too far from home for any considerable length of time, and it’s not like George could do much jumping anyway. 

Perry, in Alex’s opinion—though he never thought he was good at these things anyway—didn’t look much like Achilles either. Much rounder in face, significantly stockier, and quite a bit hairier (in addition to the scruffy beard, Alex couldn’t help but notice his forearms when the sleeves of his sweater rode up as he hugged his son), it was mostly just his paler complexion and dark hair (though Perry’s was streaked with grey) that had been passed down to Achilles. 

Regardless of it all, what stuck out the most to Alex was that both of them looked kind. 

Achilles stepped to the side to let his parents into the foyer, and in doing so, also revealed Alex who had been standing, frozen in thought, by the storage closet. He motioned for him to step forward. “I want to introduce you to—”

“Oh, you must be Alex, it is so wonderful to finally meet you, love!” Apolline rushed forward and embraced him tightly as if he were her own. 

It took him a second to recover from the shock—she seemed to have unearthed within him a memory, with the faint scent of her floral perfume, the eagerness in which she held him—but with a little shake of his head, he pulled himself together and returned her hug. 

“Great meeting you, Mrs. Desrosiers, ma’am!” Alex offered Perry his hand. “Mr. Robinson, sir!” 

“Perry,” Achilles’ father said with a firm nod and an equally firm, callused grip. 

Shaking aside their protests, Alex quickly gathered their luggage and carried it into the bedroom. When he returned, Achilles was already quite deep into the house tour, sharing the renovations he’d had Robin make in the kitchen. Unsure of what to do, Alex stood patiently by the door until Perry gestured for him to join them. 

“—and that’s Voltaire. Cam basically forced him onto me—not too hard hard to believe, is it—but no regrets, he’s a very good boy, saved me a number of times this year…” 

The ease with which Achilles spoke with them—there was no awkwardness, no hints of inauthenticity. There was respect—from both sides—but none of the heavy-handed deference George sometimes seemed to demand. The warmth, the intimacy, their relaxation. It was all palpable. Alex was in awe. 

Even when they finally sat for lunch, their encouragement hadn’t dissipated one bit. They had complimented the food, calling out Alex’s shrimp tartlet recipe as “impeccably flavorful” and absolutelyshowering his focaccia with praise. They were equally generous with their curiosity and their laughter, and had seemed genuinely impressed after asking Alex about his pro-sports goals, for despite not having seen their son for over a year, Perry and Apolline had made sure to include Alex in their conversations. 

And after lunch, it was Apolline who led him to the living room to chat as Achilles and Perry tackled the dishes. 

“Achilles has told us so much about you,” she said, taking his hand in hers. “He’s had a bit of a rough year, hasn’t he, now? Perry and I are incredibly grateful for what you’ve done for him.” 

“Oh!” Alex blushed under her gaze and had to look away. “Well, he’s really done a lot for me, too…” 

What would it have been like to have grown up in a household like this one? Likely it had had its own challenges—both clearly had busy schedules, and the expectations to succeed must’ve been enormous, clearly—but while Achilles had clearly fallen victim to the suffocating pressure, he had always blamed himself and his surrounding society and peers rather than his parents, and had never shied away from sharing his privilege growing up in a home that was not only wealthy, but also very much filled with love. 

As difficult as it was, at 2pm, he had to drag himself away. He had wanted to give Achilles some time alone with his parents regardless, but he also needed to head back to 1 River Road to help his grandparents prepare dinner—the Robinsons were joining them tonight. It’d been his own idea, and one that Evelyn had wholeheartedly supported—a way to “welcome Perry back to town!” before Lewis caught wind of the news and used it as an excuse to probably throw a celebration for Stardew’s “returning celebrity alumnus of the community.” 

But he had had his own ulterior motives, too, in suggesting the dinner, which he had of course kept to himself. Perhaps George would take notice of Achilles’ dynamic with his parents. Perhaps some of it would rub off on him. His hopes weren’t high, but it couldn’t hurt, right? 

“Thank you so much again for lunch, love, if was delicious.” Apolline enveloped him in another hug after he had tugged on his new sneakers. “We’ll see you tonight!” 

Alex cheerily waved goodbye to Achilles and his parents, though his grin faded just a bit as he made the 15 minute trek back into Pelican Town, all the while wondering if, just perhaps, he could one day maybe be a part of a family like that, too. 

*****

“Well, well, well!” Apolline had taken a seat back at the kitchen table and was pouring herself another cup of tea. “He seems like a very kind boy.” She turned to her husband, who was very closely examining one of the potted plants in Achilles’ kitchen. “Perry? What did you think of Alex?” 

He jumped, nearly knocking over the crocus, before returning to the kitchen. “Alex? Oh yes, very nice young man. I knew his mother, you know.” 

“Huh, did you really? Oh, actually, yes, I suppose that makes sense…” 

“Not very well,” Perry clarified, fighting back a yawn. “A few years younger than me, she was a sweet girl. Clara, I think her name was. He looks like her.” 

At this, Achilles furrowed his brow. Even without Alex’s Spirit’s Eve memory, he’d seen her pictures on the walls of 1 River Road. “Does he? People usually say the opposite.” 

Perry shrugged and stifled another yawn. “Not the color of them, but still something about his eyes. Maybe his nose. It has been over a decade, I suppose I could be misremembering…” 

Apolline waved him away with a flutter of her fingers. “Perry, why don’t you go to bed.” 

“No, no, I’m all right, don’t wanna miss—”

“It’s all right. Take a shower, take a nap, we’ve got all week. Anyway, you’ll need all your energy in case George is in the mood to battle it out over something or another…” Achilles walked his dad to his bedroom and handed him one of the towels he’d purchased the day before. “Toothbrushes and shampoo and stuff are in the bathroom.” 

Perry nodded his thanks as he unzipped his coat, setting it behind the desk chair. He took note of the typewriter, but only gave a small nod before saying, “Looks good.” 

“Yeah, I… started something new. Don’t know where it’ll go, if anywhere, but I’m… feeling pretty good about it.” 

Perry nodded. Gave the neatly stacked pile of manuscript drafts a light tap with his finger as Achilles continued to blabber. 

“I’ll be teaching at the middle school in the new year, though. Well, substitute teaching, but still… Don’t worry, I’m… getting out of the house. Staying productive.”  

Giving no sign, and yet every sign, that he had heard his son, Perry turned away from the desk and rested a hand on the back of the chair. “Seems like you’ve made a nice life out here. I’m proud of you.” 

“Oh. Right.” Achilles swallowed. After a beat, he hurried to the closet as Perry swiftly transitioned back to George. 

“Speaking of the old geezer, though… You, uh, need me to talk to him?” Perry’s eyes, the same brown as Achilles’, followed his son as he opened the closet door to point out the extra blankets. “You said he was saying some things… happy to, uh, have a chat with him, if you think it might help, he knew me and your grandpa pretty well…” 

“Hmm?” Achilles paused, hand on the closet door. “Oh. No, dad, it’s ok. Alex and I, we’ve… he talked to him and he said it’s been getting better. But thanks.” 

After showing his dad how to use the shower, Achilles returned to the kitchen where Apolline, still bright eyed and full of energy, had continued to sip her tea. She set down her phone when he entered and stood to pour her son his own cup before primly crossing her legs and bumping his knee with her toe. “So, tell me. Alex—do you think he’s the one?” 

Achilles had instantly turned red and spluttered, though perhaps one could argue both reactions were from the piping hot tea on which he’d just burned his tongue. He took a second to recover before managing to choke out, “It’s been barely half a season.” But under her expectant gaze, he took another swallow, slow as he savored his response.

“I mean… I wouldn’t mind. I don’t know. I hope so.” He paused and gave his tea a little swirl, watched the last sugar crystals dissolve amongst the leaves. “I really like him, Mom.” 

“I can tell, love. I like him, too.” She patted his knee. “We’ll cross our fingers, shall we?” 

*****

Dinner had been a success. 

It had started off on a high—Achilles had previously informed Perry and Apolline that the Mullners rarely drank, so they had gifted their hosts with a set of infused extra virgin olive oils and vinegars instead, and there were few things Evelyn loved more than that.  

And from there, things had remained smooth. As to be expected, the Robinsons were pleasant guests, and under Apolline’s charm, even George, whom Alex had been watching closely throughout the night, seemed less combative than usual, even bestowing one of Achilles’ jokes a hacking chuckle by the end of the night. 

Perry and Apolline had bid them farewell after dessert, and not long after Evelyn and George— who hadn’t stayed up for New Year’s in decades—retired to their bedroom, leaving Alex and Achilles alone for the first time since the morning. 

They kept their voices low, like teenagers, sitting with legs tangled on the couch that the Mullners had finally decided to purchase this past Winter Star (“although now that Alex is spending so much dang time with that Achilles, we need it even less,” George had complained).  

“I liked your parents,” Alex whispered, his face barely an inch away from Achilles’. It wasn’t a particularly large couch. 

“And they liked you. Though no surprises there, of course.” 

Those first four little words sent a thrill down Alex’s spine, joined by a glowing warmth that spread outwards from his heart. “They’re… very kind.” 

“It truly is a wonder how they birthed me, huh?” 

“No,” Alex scolded. He placed his forefinger lightly against Achilles’ forehead. “I was going to say they’re just like you.” 

“Hmm. If that’s the case,” Achilles murmured, gently clasping the entirety of Alex’s hand in his and bringing it slowly to his lips, “Then they’ll be sure to love you, too.” 

*****

A series of creaks seemingly from Evelyn and George’s room sent Alex, Achilles, and Dusty (who seemed to understand the stakes) turning off the living room lights and tiptoeing to the bedroom.

Alex was toweling off from his shower when Achilles gave a soft whistle from the bean bag.

“Now that is the body of a gold-medal Artemian with a multi-million dollar Toria sponsorship and the cover of Mod magazine. Did I only say body? Sorry, body and face. Like Helen of Troy. I’d launch a thousand ships for you, hmm.” Under his breath, he added for himself “Although I suppose you’re more of a Patroclus… kind of. Eh… a stretch…” 

Alex laughed and flashed a quick pose. “What can I say? I want to look good for you.” 

“Yeah, yeah, I bet you say that to all the girls… It’s pretty warm tonight, though, how about I make you an offer of $5 to not sleep with that on.” Achilles nodded at the t shirt Alex was holding between his hands. 

“Creep.” But he laughed and pretended to throw the shirt at Achilles before folding it and placing it back in a drawer. “Also, you’re worth way more than $5, you cheapskate. Heck, I’m worth way more than $5…” 

“Priceless, baby.” Achilles followed his lead, standing up from the bean bag and removing his blazer when his hand collided with something pointy jabbing the fabric. “Oh shit, I forgot, I must’ve put this in my pocket—” He withdrew the sheet of paper from this morning. “Lewis’ secret little love note to me.”

“El oh el. ‘Kay, so what is it actually?” 

“It’s just the letter my grandpa wrote me when he left me the farm. What can I say, I was feeling a bit saccharine this morning, found myself suddenly thinking about this…”  

“I don’t know what sack-a-rin means.” 

“As cheesy as those Joja pizzas Shane keeps trying to bribe me with. Like overly sentimental. Come here, take a look for yourself.” 

He unfolded the note, Alex peering over his shoulder. 

Dear Achilles,

If you’re reading this, you must be in dire need of a change.

The same thing happened to me, long ago. I’d lost sight of what mattered most in life… real connections with other people and nature. So I dropped everything and moved to the place I truly belong.

I’ve enclosed the deed to that place… my pride and joy: Strawberry Farm. It’s located in Stardew Valley, on the southern coast. It’s the perfect place to start your new life. 

This was my most precious gift of all, and now it’s yours. I know you’ll honor the family name, my boy. 

Good luck.

Love, Grandpa 

P.S. If Lewis is still alive say hi to the old guy for me, will ya? 

Achilles sighed, tossing it to Alex who was still reading, and finished changing for bed. 

“It was kind of him to put faith in me to honor the family name, I’m sure he’s real proud watching me outsource 90% of running the farm to my neighbor.” He looked out the window, up at the stars and heavens above. “Sorry grandpa, I failed ya.” He returned to the bed, turning back the sheets and casually adding, “Or do we think he’s in hell? I didn’t know the guy that well.”

A joke, clearly, but even so, it wasn’t hard to discern the faintest trace of bitterness in his words. Achilles had come a long way in the most recent weeks, but the feeling of failure was not something that disappeared overnight, or even over seasons.

“‘Honor the family name…’” Alex looked over at Achilles who was now making himself comfortable under the covers. “You would zero in on that part.” 

“What’s that supposed to mean?” 

He joined Achilles in bed, lying his head above his shoulder as he raised the letter above them and gave it a flick. “Ash, he literally says right there that the things that matter most in life are real connections with other people and nature. I may have gotten like a C minus in English class, but I’m still pretty sure the family name part is like, the result. Not the main idea.”

“Let me see that.” Achilles snatched the letter back and gave it another read through. But rather agree with Alex’s analysis, he merely asked, “So what do you think I was supposed to do, then?” 

“I don’t know if you were supposed to do anything except just, I dunno, live your life, a new life. Connect with nature. Connect with people.” 

“Do you think I did that?” 

“Do you think you did that?” 

No response managed to escape the tightly wound, scrunchy little frown of Achilles’ lips. His eyes remained focus on the the letter, now gripped tightly between both his hands, but it was clear from his hard, frozen stare that rather than reading, he was thinking hard. 

Did you do it, ya bastard? 

Connect with nature, connect with people. Sure, he’d done it. That being said, there hadn’t been anything particularly special to doing any of it, in fact, it would’ve been difficult not to do it, given that there was very little else out here to do in Stardew Valley besides simply existing among nature and existing among people. It’d been easy. 

“I mean…” He had found his voice again. “Yes. Yes, of course I did that, it would have been harder not to, all there is out here are trees and nosy ass neighbors—” 

“Okay.” Alex gently tugged the letter from Achilles’ grasp and set it on his nightstand. He flicked off the lamp, and in the dark, they could hear the soft clink of Dusty’s tags as the dog padded to his bed in the corner. “Then you started your new life!” 

Did you, though? 

Achilles glanced over at Alex before his gaze drifted to the window behind, to the crack between the curtains where he could just barely make out the various swaying shadows of the bucolic valley he now called home. A deep inhale of the fresh, sweetly scented breeze drifting through quieted his thoughts and his self-doubts, and slowly made space for different sorts of sounds. 

“You started your new life, and you honored your family name. Both of them, Robinson and Desrosiers. You did!” From beneath the covers, Alex squeezed his hand. 

Yeah.

Yeah?

Yeah. I suppose I did. 

But he had chosen to save the words inside his head, just a little something for himself, and after a minute, he felt Alex, impatient, rapidly tapping his chest with his pointer finger. “Hey, you are listening to me, right, you punk?” 

Achilles couldn’t help but smile at the earnestness in his voice, and as he brought Alex’s fingers softly to his lips, he managed to murmur through his laugh, “Yeah, yeah, don’t worry. I’m listening.”

How does Spring Boot simplify development?

Spring Boot simplifies Java development by offering a streamlined, production-ready framework that reduces boilerplate code and configuration complexities. It is built on top of the Spring Framework but eliminates much of the setup and manual configurations required in traditional Spring applications. This leads to faster development, easier deployment, and improved productivity.

One of the core features of Spring Boot is its auto-configuration. Instead of manually defining beans or XML configurations, Spring Boot automatically configures your application based on the libraries present in your classpath. For example, if you include Spring Data JPA, it auto-configures database settings, assuming typical defaults, which can still be overridden as needed.

Spring Boot also comes with an embedded web server (like Tomcat, Jetty, or Undertow). This means developers can run web applications without deploying WAR files to an external server—just run the application as a Java program, and it serves content directly. This makes testing, debugging, and deployment much faster and simpler.

Additionally, Spring Boot includes starter dependencies, which are curated dependency sets for common tasks like web development, security, and data access. These starters remove the guesswork from version compatibility and help avoid dependency conflicts.

Another significant feature is the Actuator, which provides out-of-the-box endpoints for monitoring and managing applications. Developers can check application health, view metrics, and track usage statistics without writing custom code.

Spring Boot promotes opinionated defaults, meaning it guides developers toward best practices and proven design patterns, allowing them to focus more on business logic than infrastructure code.

Because of these advantages, Spring Boot is a critical skill for modern web application development in Java. Anyone aiming to master backend technologies should consider enrolling in a java full stack developer course to build strong expertise in Spring Boot and related technologies.

Provide insights into securing Java web and desktop applications.

Securing Java web and desktop applications requires a combination of best practices, security libraries, and frameworks to prevent vulnerabilities like SQL injection, XSS, CSRF, and unauthorized access. Here’s a deep dive into key security measures:

1. Secure Authentication and Authorization

Use Strong Authentication Mechanisms

Implement OAuth 2.0, OpenID Connect, or SAML for authentication.

Use Spring Security for web applications.

Enforce multi-factor authentication (MFA) for added security.

Example (Spring Security Basic Authentication in Java Web App)java@Configuration @EnableWebSecurity public class SecurityConfig { @Bean public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { http .authorizeHttpRequests(auth -> auth .requestMatchers("/admin/**").hasRole("ADMIN") .anyRequest().authenticated()) .httpBasic(); return http.build(); } }Implement Role-Based Access Control (RBAC)

Define roles and permissions for users.

Use JWT (JSON Web Tokens) for securing APIs.

Example (Securing API using JWT in Spring Boot)javapublic class JwtUtil { private static final String SECRET_KEY = "secureKey"; public String generateToken(String username) { return Jwts.builder() .setSubject(username) .setIssuedAt(new Date()) .setExpiration(new Date(System.currentTimeMillis() + 1000 * 60 * 60)) .signWith(SignatureAlgorithm.HS256, SECRET_KEY) .compact(); } }

2. Secure Data Storage and Transmission

Use Secure Communication (HTTPS & TLS)

Use TLS 1.2+ for encrypting data in transit.

Enforce HSTS (HTTP Strict Transport Security).

Encrypt Sensitive Data

Store passwords using bcrypt, PBKDF2, or Argon2.

Use AES-256 for encrypting sensitive data.

Example (Hashing Passwords in Java)javaimport org.mindrot.jbcrypt.BCrypt;public class PasswordSecurity { public static String hashPassword(String password) { return BCrypt.hashpw(password, BCrypt.gensalt(12)); } public static boolean verifyPassword(String password, String hashedPassword) { return BCrypt.checkpw(password, hashedPassword); } }

Use Secure Database Connections

Use parameterized queries to prevent SQL injection.

Disable database user permissions that are not required.

Example (Using Prepared Statements in JDBC)javaPreparedStatement stmt = connection.prepareStatement("SELECT * FROM users WHERE username = ?"); stmt.setString(1, username); ResultSet rs = stmt.executeQuery();

3. Protect Against Common Web Vulnerabilities

Prevent SQL Injection

Always use ORM frameworks (Hibernate, JPA) to manage queries securely.

Mitigate Cross-Site Scripting (XSS)

Escape user input in web views using OWASP Java Encoder.

Use Content Security Policy (CSP) headers.

Prevent Cross-Site Request Forgery (CSRF)

Use CSRF tokens in forms.

Enable CSRF protection in Spring Security.

Example (Enabling CSRF Protection in Spring Security)javahttp.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());

4. Secure File Uploads and Deserialization

Validate File Uploads

Restrict allowed file types (e.g., only images, PDFs).

Use virus scanning (e.g., ClamAV).

Example (Checking File Type in Java)javaif (!file.getContentType().equals("application/pdf")) { throw new SecurityException("Invalid file type"); }

Avoid Untrusted Deserialization

Use whitelisting for allowed classes.

Prefer JSON over Java serialization.

Example (Disable Unsafe Object Deserialization in Java)javaObjectInputStream ois = new ObjectInputStream(inputStream) { @Override protected Class<?> resolveClass(ObjectStreamClass desc) throws IOException, ClassNotFoundException { throw new InvalidClassException("Deserialization is not allowed"); } };

5. Secure Desktop Java Applications

Use Code Signing

Sign JAR files using Java Keytool to prevent tampering.

shjarsigner -keystore mykeystore.jks -signedjar SecureApp.jar MyApp.jar myaliasRestrict JavaFX/Swing Application Permissions

Use Java Security Manager (deprecated but useful for legacy apps).

Restrict access to file system, network, and system properties.

Encrypt Local Data Storage

Use AES encryption for storing local files.

Example (Encrypting Files with AES in Java)javaCipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(key, "AES")); byte[] encrypted = cipher.doFinal(data);

6. Logging and Monitoring for Security

Use Secure Logging Frameworks

Use logback or SLF4J.

Avoid logging sensitive data like passwords.

Monitor for Anomalies

Implement Intrusion Detection Systems (IDS).

Use audit trails and security alerts.

7. Best Practices for Securing Java Applications

✅ Keep dependencies up to date (Use OWASP Dependency Check). ✅ Run security scans (SAST, DAST) using SonarQube, Checkmarx. ✅ Apply the principle of least privilege for database and API access. ✅ Enforce strong password policies (min length, special characters). ✅ Use API Gateway and rate limiting for public-facing APIs.

Conclusion

Securing Java web and desktop applications requires multi-layered security across authentication, data protection, and vulnerability mitigation. By following best practices like strong encryption, secure coding techniques, and continuous monitoring, developers can protect applications against cyber threats.

Struggling to build scalable and efficient Java applications? Hire Spring Boot developer to build high-performing Java applications!

What is Spring Boot?

The open-source development stack Spring Boot functions as a Java-based framework which enables developers to build production-ready standalone Spring applications without complexity. The framework uses conventions to eliminate unnecessary configuration requirements thus developers can begin their work without extensive boilerplate code. Spring Boot functions as an extension of the Spring framework which remains a fundamental component of the Java programming world since its launch twenty years ago.

The main advantage of Spring Boot emerges from its effortless integration with multiple technologies. Through its built-in support Spring Boot makes it easy to integrate with databases, messaging systems, cloud platforms and third-party APIs.

How Spring Boot Ensures Smooth Integration with Other Technologies

1. Auto-Configuration: Simplifying Setup and Integration

The main strength of Spring Boot exists in its automated configuration features. The dependencies you add to your project trigger Spring to automatically configure your Spring application. Your application receives automatic configuration from Spring Boot whenever you add dependencies for specific technologies such as databases or messaging systems.

Your project will receive automatic configuration through the dependency addition of "spring-boot-starter-data-jpa" to your codebase. When Spring Boot detects this dependency it creates a DataSource bean while incorporating Hibernate as the default JPA provider. The automatic configuration feature removes the requirement of manual setup while minimizing potential human mistakes.

Auto-configuration delivers exceptional value when dealing with multiple technologies because it enables seamless component integration without needing complex configuration setups.

2. Starter Dependencies: Streamlining Dependency Management

Spring Boot simplifies dependency management through its extensive collection of "starter" dependencies which help developers easily integrate project dependencies. The starter dependencies include pre-packaged dependency collections for common technology integrations which simplify integration processes.

Through 'spring-boot-starter-web' you gain embedded Tomcat together with Spring MVC and Jackson to process JSON which enables web application development. Anglers who use the 'spring-boot-starter-data-mongodb' dependency gain access to libraries which enable MongoDB integration.

Starter dependencies simplify dependency management by automating the process of dependency addition thus reducing version conflicts while ensuring smooth integration with target technologies.

3. Embedded Servers: Simplifying Deployment

Spring Boot provides native support for running applications through embedded servers including Tomcat, Jetty and Undertow. The framework enables you to create a single JAR file which contains all necessary components to execute your application with its built-in web server. The deployment process becomes simpler because embedded servers integrate all necessary components into a single JAR file which eliminates the requirement to handle external server configuration.

Embedded servers help application integration by creating a uniform runtime environment that simplifies the deployment of other technologies. Each microservice in your architecture can exist as a standalone JAR file that embeds its own server which simplifies service management and scalability.

4. Spring Data: Simplifying Database Integration

Through its integration with Spring Data Spring Boot enables developers to work effortlessly with diverse database systems including relational databases (MySQL and PostgreSQL) and NoSQL databases (MongoDB and Cassandra). Spring Data delivers a standardized programming interface for data access which operates across all database platforms.

The Spring Data JPA enables users to work with relational databases through simple interfaces when defining their data models and repositories. Spring Boot generates database queries automatically while it manages all connection operations to the database.

Spring Data MongoDB enables the same simple interface-based programming model for developers who work with MongoDB NoSQL databases. Through Spring Boot the required MongoDB connections will be set up automatically while the data access processes are handled by the framework.

5. Spring Cloud: Simplifying Cloud Integration

Through its Spring Cloud integration Spring Boot enables developers to create cloud-native applications which connect to AWS Azure and Google Cloud platforms. Spring Cloud delivers a complete suite of tools and libraries that help developers construct distributed systems through service discovery and configuration management and load balancing capabilities.

When developing microservices architecture you can leverage Spring Cloud Netflix to enable service discovery with Eureka and load balancing with Ribbon and circuit breaking with Hystrix. Spring Boot takes care of component configuration and enables their smooth operation.

Spring Cloud enables developers to integrate cloud-native databases alongside messaging systems and other services which simplifies the deployment of cloud-native applications.

6. RESTful Web Services: Simplifying API Integration

Spring Boot provides straightforward tools for developing and utilizing RESTful web services because these services represent a standard method to interface with external APIs. Through its Spring MVC integration Spring Boot delivers a standardized approach to create RESTful web services.

Through annotations like `@RestController` Spring Boot quickens web service processing automatically. Through the RestTemplate class users can consume RESTful web services to make integrating with external APIs easier.

Spring Boot enables developers to build SOAP web services and consume them through its versatile framework which supports a broad spectrum of API and service integration.

7. Messaging Systems: Simplifying Event-Driven Integration

Through its messaging system, integrations with Apache Kafka RabbitMQ and JMS Spring Boot enables developers to create event-driven applications that connect with other systems without complexity. Spring Boot delivers a standard programming interface which enables developers to work with messages across all messaging solutions.

When using Apache Kafka with Spring Boot you can utilize the `@KafkaListener` annotation to create message listeners which Spring Boot automatically handles Kafka connections and message processing. Spring Boot manages the message listener code through its built-in automatic connection creation and handling process when using either the RabbitListener annotation or the @RabbitListener annotation.

The system allows developers to create event-driven applications which seamlessly connect to microservices and cloud platforms and third-party APIs.

8. Security: Simplifying Secure Integration

Through its Spring Security integration Spring Boot provides straightforward methods to secure your application and establish secure system connections. The Spring Security framework includes complete libraries and tools to build authentication and authorization systems along with other security features.

Spring Security enables OAuth2 authentication as a standard method to protect RESTful web services while enabling integration with third-party APIs. Spring Boot handles all required security component configuration automatically while maintaining a smooth integration between them.

Spring Security enables secure application integration through its support for LDAP as well as SAML and multiple security protocols which makes it a flexible solution for protecting your application and its secure systems.

9. Testing: Simplifying Integration Testing

Spring Boot achieves effortless integration testing through its support for testing frameworks JUnit and Spring Test alongside Mockito. Spring Boot delivers a unified programming structure for creating integration tests which operates independently from the selected underlying framework.

Through the `@SpringBootTest` annotation you can create integration tests which Spring Boot will automatically set up and verify component connectivity. Testing application integration with other technologies becomes straightforward because of this feature.

10. Monitoring and Management: Simplifying Operational Integration

Spring Boot integrates with monitoring and management tools such as Spring Boot Actuator, Micrometer and Prometheus which enables easy production-level application monitoring and management. Spring Boot Actuator delivers endpoints that enable application monitoring and management through health checks and metrics and environment information retrieval.

Using Spring Boot Actuator you can deploy health check endpoints that assist both load balancers and monitoring tools to assess your application's operational state. Micrometer enables metric collection that Prometheus monitoring tools use to track your application performance.

What are the top 10 Java SpringBoot interview questions?

Here’s a list of the Top 10 Java Spring Boot Interview Questions with detailed answers. At the end, I’ll include a promotion for Spring Online Training to help learners dive deeper into this popular framework.

1. What is Spring Boot, and how does it differ from the Spring Framework?

Answer: Spring Boot is an extension of the Spring Framework, designed to simplify the setup and development of new Spring applications by providing an opinionated approach and avoiding complex configuration. It comes with embedded servers, auto-configuration, and production-ready features, making it faster to get started with a project compared to traditional Spring Framework projects, which require more manual setup and configuration.

2. How does Spring Boot handle dependency management?

Answer: Spring Boot simplifies dependency management using Spring Boot Starters — pre-defined dependencies that bundle commonly used libraries and configurations. For instance, spring-boot-starter-web includes dependencies for building a web application, including embedded Tomcat, Spring MVC, etc. Spring Boot also supports dependency versions automatically via its parent pom.xml, ensuring compatibility.

3. What is the purpose of the @SpringBootApplication annotation?

Answer: The @SpringBootApplication annotation is a convenience annotation that combines:

@Configuration - Marks the class as a source of bean definitions.

@EnableAutoConfiguration - Enables Spring Boot’s auto-configuration feature.

@ComponentScan - Scans for components in the package.

This annotation is usually placed on the main class to bootstrap the application.

4. Explain the role of the application.properties or application.yml file in Spring Boot.

Answer: application.properties or application.yml files are used to configure the application's settings, including database configurations, server port, logging levels, and more. Spring Boot reads these files on startup, allowing developers to manage configuration without hardcoding them in code. The .yml format is more readable and hierarchical compared to .properties.

5. How does Spring Boot handle exception management?

Answer: Spring Boot provides a global exception handling mechanism via the @ControllerAdvice annotation, which allows you to define a centralized exception handler across the application. With @ExceptionHandler within a @ControllerAdvice, you can customize error responses based on the exception type.

6. What is Spring Boot Actuator, and what are its benefits?

Answer: Spring Boot Actuator provides a set of endpoints to monitor and manage a Spring Boot application, such as /health, /metrics, /info, and more. It helps with application diagnostics and monitoring, offering insights into application health, runtime metrics, environment properties, and request tracing, making it easier to monitor in production environments.

7. What is the difference between @RestController and @Controller?

Answer: @RestController is a specialized version of @Controller in Spring MVC. It is used for RESTful web services, combining @Controller and @ResponseBody annotations. This means that every method in a @RestController will return data (usually in JSON format) directly, rather than resolving to a view template. @Controller is used when views (e.g., JSP, Thymeleaf) are involved in rendering the response.

8. How does Spring Boot handle database connectivity and configuration?

Answer: Spring Boot simplifies database connectivity by providing auto-configuration for supported databases (e.g., MySQL, PostgreSQL). Using the spring.datasource.* properties in application.properties, developers can configure data source properties. For in-memory databases like H2, Spring Boot can automatically create and initialize a database using SQL scripts if placed in src/main/resources.

9. What are Profiles in Spring Boot, and how are they used?

Answer: Spring Boot Profiles allow applications to define different configurations for different environments (e.g., development, testing, production). Profiles can be set using spring.profiles.active=<profile> in application.properties or with environment-specific configuration files like application-dev.properties. Profiles enable smooth switching between configurations without changing the codebase.

10. What is the role of embedded servers in Spring Boot, and how can you configure them?

Answer: Spring Boot includes embedded servers like Tomcat, Jetty, and Undertow, enabling applications to be run independently without external deployment. This setup is useful for microservices. You can configure the embedded server (e.g., server port, SSL settings) via application.properties with properties like server.port, server.ssl.*, etc. This helps create stand-alone applications that are easy to deploy.

For Spring Interview Question Visit :- 35 Easy Spring Framework Interview Questions and Answers

Top Spring Interview Questions and Answers (2024)

[vatt-world]

) Explain the internal working of Spring Boot. Spring Boot works by automatically setting up default configurations based on the tools our project uses. It includes built-in servers like Tomcat to run our applications. Special starter packages make it easy to connect with other technologies. We can customize settings with simple annotations and properties files. The Spring Application class starts the app, and Spring Boot Actuator offers tools for monitoring and managing it

) How does a Spring application get started? A Spring application typically starts by initializing a Spring ApplicationContext, which manages the beans and dependencies. In Spring Boot, this is often triggered by calling SpringApplication.run() in the main method, which sets up the default configuration and starts the embedded server if necessary.

What is a Spring Bean? A Spring Bean is an object managed by the Spring framework. The framework creates, configures, and connects these beans for us, making it easier to manage dependencies and the lifecycle of objects.

Spring Boot dependency management makes it easier to handle the dependencies that our project depends on. Instead of manually keeping track of them, Spring Boot helps us manage them automatically

If a starter dependency includes conflicting versions of libraries with other dependencies, Spring Boot's dependency management resolves this by using a concept called "dependency resolution." It ensures that only one version of each library is included in the final application, prioritizing the most compatible version. This helps prevent runtime errors caused by conflicting dependencies and ensures the smooth functioning of the application

How to disable a specific auto-configuration class? We can disable specific auto-configuration classes in Spring Boot by using the exclude attribute of the @EnableAutoConfiguration annotation or by setting the spring.autoconfigure.exclude property in our application.properties or application.yml file.

Describe the flow of HTTPS requests through a Spring Boot application. In a Spring Boot application, HTTPS requests first pass through the embedded server's security layer, which manages SSL/TLS encryption. Then, the requests are routed to appropriate controllers based on URL mappings.

The @SpringBootApplication annotation is a convenience annotation that combines @Configuration, @EnableAutoConfiguration, and @ComponentScan annotations. It is used to mark the main class of a Spring Boot application and trigger auto-configuration and component scanning. On the other hand, @EnableAutoConfiguration specifically enables Spring Boot's auto-configuration mechanism, which attempts to automatically configure our application based on the jar dependencies we have added.

I would:

Use dependency injection to manage dependencies.

Utilize Spring Profiles for environment-specific configurations.

Group related beans in separate configuration classes.

Use @ComponentScan to automatically discover beans.

You have a singleton bean that needs to be thread-safe. What approaches would you take to ensure its thread safety? I would:

Use synchronized methods or blocks to control access to critical sections.

Use ThreadLocal to provide thread-confined objects.

Implement stateless beans where possible to avoid share

To enable Spring Boot Actuator, we simply add the spring-boot-starter-actuator dependency to our project’s build file. O

The dev-tools dependency in Spring Boot provides features that enhance the development experience. It enables automatic restarts of our application when code changes are detected, which is faster than restarting manually.

To test a Spring Boot application, we use different tools and annotations. For testing the whole application together, we use @SpringBootTest. When we want to test just a part of our application, like the web layer, we use @WebMvcTest

How do you handle exceptions in Spring Boot applications? In Spring Boot, I handle errors by creating a special class with @ControllerAdvice or @RestControllerAdvice. This class has methods marked with @ExceptionHandler that deal with different types of errors. These methods help make sure that when something goes wrong, my application responds in a helpful way, like sending a clear error message or a specific error code.

) How can you disable specific auto-configuration classes in Spring Boot? We can disable specific auto-configuration classes in Spring Boot by using the @SpringBootApplication annotation with the exclude attribute. For example, @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class}) will disable the DataSourceAutoConfiguration class.

Versioning in REST APIs helps manage changes without breaking existing clients. It allows different versions of the API to exist at the same time, making it easier for clients to upgrade gradually. We can version REST APIs in several ways: include the version number in the URL (e.g., /api/v1/resource), add a version parameter in the URL (e.g., /api/resource?version=1), use custom headers to specify the version (e.g., Accept: application/vnd.example.v1+json), or use media types for versioning (e.g., application/vnd.example.v1+json).

ResponseEntity in Spring Boot is used to customize responses. It lets us set HTTP status codes, add custom headers, and return response data as Java objects. This flexibility helps create detailed and informative responses. For example, new ResponseEntity<>("Hello, World!", HttpStatus.OK) sends back "Hello, World!" with a status code of 200 OK.

To disable the default server and enable a different one in Spring Boot, exclude the default server dependency in the pom.xml or build.gradle file and add the dependency for the desired server. For example, to switch from Tomcat to Jetty, exclude the Tomcat dependency and include the Jetty dependency in our project configuration.

@ComponentScan annotation in Spring tells the framework where to look for components, services, and configurations. It automatically discovers and registers beans in the specified packages, eliminating the need for manual bean registration and making it easier to manage and scale the application's architecture. EnableAutoConfiguration annotation in Spring Boot tells the framework to automatically configure our application based on the libraries we have included. This means Spring Boot can set up our project with the default settings that are most likely to work well for our setup.

EnableAsync annotation in Spring enables asynchronous method execution. It allows methods to run in the background on a separate thread, improving performance by freeing up the main thread for other tasks.

RestController annotation in Spring marks a class as a RESTful web service controller. It combines @Controller and @ResponseBody, meaning the methods in the class automatically return JSON or XML responses, making it easy to create REST APIs.

EnableScheduling is an annotation in Spring Framework used to enable scheduling capabilities for methods within a Spring application. It allows methods annotated with @Scheduled to be executed based on specified time intervals or cron expressions

The @Value annotation is a powerful tool in Spring Boot for injecting configuration values into your beans. Whether you need to inject simple properties, system properties, environment variables, or more complex SpEL expressions, @Value makes it easy to externalize configuration and keep your application flexible and maintainable. The Spring Boot @Value annotation streamlines the process, ensuring that your configuration management is efficient and straightforward.

How can you enable cross-origin resource sharing (CORS) in a Spring Boot application?

To enable CORS in a Spring Boot application, you can follow these steps: Using @CrossOrigin Annotation: Apply the @CrossOrigin annotation to specific controller methods or classes to enable CORS for those endpoints. Global CORS Configuration: Implement a WebMvcConfigurer bean to configure CORS globally for all endpoints in your application. The annotation allows you to specify the allowed…

Jaeger Integration with Spring Cloud

In today’s complex landscape of highly distributed microservices, monitoring, and tracing are essential tools for understanding application performance and effectively diagnosing issues. Distributed tracing allows us to track requests as they traverse multiple services, providing valuable insights into potential bottlenecks and latency problems. In this blog post, we will explore the process of setting up distributed tracing in a Spring Boot application, utilizing OpenTelemetry and Jaeger.

Understanding Distributed Tracing

Distributed tracing is a technique that helps developers and operators track requests as they move across various microservices or components of an application. It provides end-to-end visibility into the path a request takes and the time it spends in each service. With this information, you can:

Identify bottlenecks: Find out which parts of your application are causing delays or performance issues.

Optimize performance: Analyze the trace data to identify opportunities for optimizing the performance of your application.

Troubleshoot errors: Quickly pinpoint the source of errors or exceptions in your system, making debugging much easier.

Introducing OpenTelemetry and Jaeger

OpenTelemetry (OTel) is indeed an open-source project that offers a set of APIs, libraries, agents, and instrumentation to help you gain observability into your applications by collecting distributed traces, metrics, and logs. OpenTelemetry is designed to be vendor-neutral and can integrate with a range of tracing systems.

Jaeger is a popular open-source distributed tracing system that can act as a backend for collecting, storing, and visualizing trace data generated by applications instrumented with OpenTelemetry.

Together, OpenTelemetry and Jaeger can be used to collect, analyze, and visualize observability data from distributed systems, providing insights into system performance and helping to troubleshoot issues.

Setting Up OpenTelemetry and Jaeger in Spring Boot

Creating an application

Let’s go to https://start.spring.io and create an application with the following dependencies.

Spring Web (required to create REST endpoints)

Spring Boot Actuator

The traces will be collected using the micrometer collector in the actuator dependence and exported using the OpenTelemetry requirement.

This would necessitate the addition of the following dependencies.

The Spring Boot parent will handle the dependency versions.

Following that, we will develop two applications.

To export the spans to Jaeger, we must first develop a span exporter bean, as seen below.

In addition, we will define the Jaeger URL where trace data will be recorded in the properties file.

Service1

Service 2

Here, we set the probability of selecting the tracing to 1, which means that every trace and span is reported to Jaeger.

We will also provide a special logging format so that the spans and traces may be seen in the application logs.

Will also configure bean for RestTemplate

Service-2

in the Controller class

The idea is to call service2 /hello api from service1 /hello api by using RestTemplate.

Starting Jaeger with Docker

To start Jaeger, we have the following docker cmd.

For Jaeger to support the OpenTelemetry input format, we need to set the COLLECTOR_OTLP_ENABLED to true

With this, will start the applications.

Now, let’s visualize the traces in Jaeger UI.

To access the Jaeger UI, open the following URL.

it was overcast today. i was able to finally put away the sunflower stalks. not sure what to do with them yet. I'm sure I'll find use.

moved the watermelon and squash seedlings in the pot. I've decided to keep them all. i mean... fuck it. so I had to space them out accordingly. i have 3 sugar babies, 2 black diamond, 2 yellow squash, and only 1 out of the 2 green squash germinated.

found a permanent spot for them both on the border between the two plots and the patio. it looks good for now. I'll more than likely need to buy 4 small trellises and configure a climbing and trailing situation.

i put the chive and spring onion seedlings in the basket and added more garlic and common chive seeds. the spring onion seedlings that came from my own stash are germinating like crazy. i didn't have enough room to interplant them between the mature ones I rerooted. hopefully this attempt is better and I didn't shock the coming chives too much being that this is their second move.

repotted the pineapple sage. the prop stem is dying, but the roots look really good. i hope the whole thing doesn't die off. the roots of the pineapple sage as a whole are fucking amazing and already wrapping around the bottom of the pot. I'm much happier with the way it sits in there now.

shook all of the herbs to get the bugs loose and sprinkled some diatomaceous earth on the soil to keep the worms away.

my seeds came in so I'm currently germinating in a water peroxide solution and I'll pop the (4) cucamelon seeds directly into a starter pot, while the pine berries will go into a moist napkin in a plastic bag, which was suggested by the website.

the shop sent the seeds super quick and gave me double the cucamlon seeds (20, paid for 10) and I couldn't even tell you how many pine berries (paid for 100, but I know there's way more because I took out a small pinch of what they gave and counted that and it came out to 40). they also sent a few flower seeds.

things are looking good. it looks as though at least one of the kabochas has been fertilized. a fucking cutworm got to one of my yard beans. i was so frustrated, i dug around it and unearthed the little fat fuck. i almost chopped it, i was so angry, but instead I dropped him off over at the lizard hole. most of the yard beans have sprouted except for a few in the front. I'm super happy with this. it also looks like my edamame pods should be ready to harvest for seed soon as they're starting to turn brown.
