The IntelliJ shortcut to run your code is ctrl+Shift+F10

WHO USES THAT. WHAT IS THAT.

It’s like it was MADE to discourage you from using it

Написать программу на Java без текстовых редакторов?

Программу на java можно создать, используя одну командную строку. (по крайней мере на windows, хз что там у других систем)

Познакомимся с некоторыми командами:

echo - команда для вывода текста. Она будет записывать код в файл;

javac - компилятор. Переведёт код в байт-код;

java - загрузчик приложений. Запускает код.

Открываем cmd. Пишем:

echo class CmdHi { public static void main(String[] args) { System.out.println("I am a good programmer!"); } } > CmdHi.java

Создастся файл CmdHi.java, внутрь запишется код, который при выполнении выведет строчку "I am a good programmer!".

Чтобы посмотреть содержимое файла, можно использовать команду more:

more CmdHi.java Вывод: class CmdHi { public static void main(String[] args) { System.out.println("I am a good programmer!"); } }

Далее программу надо скомпилировать:

javac CmdHi.java

После чего можем запустить код, указав скомпилированный класс:

java CmdHi

Результат:

I am a good programmer!

Скрин для наглядности

Кстати, с 11 версии джавы простейшие программы не требуют компиляции, поэтому сразу после echo можно сделать так

java Hi.java

Наблюдение: русские символы при выводе в командной строке могут не читаться

Hey guys! If you have JetBrains IDEs you can have a pet like VScode!

So I'm playing around with Angular. I'm not really a fan. I think the HTML syntax for it was created in Hell. But it runs nicely on my 15" MacBook Air.

Brief CLion Adventure

Or: How Not To Remove Features.

Recently, I started setting my PC to light mode again, just because it's becoming easier on my eyes during daytime. Mostly that's just flipping a switch in the system settings, and most of my apps respond to that already. Some applications only support one mode, some need a switch flipped inside the app settings, no big deal.

CLion used to support responding to the system theme automatically, but support for that was apparently removed for Linux an update or two ago. I don't know why.

Now, since CLion doesn't do it automatically anymore, I'm trying to switch the IDE to light theme manually. But it doesn't let me. The button to switch themes is completely greyed out, and there's no other theme-related option in sight. A quick web search for the problem yields nothing useful. I know for a fact that CLion supports a light theme (heck, it even supports custom themes), so why isn't it letting me switch?

I search around more for how appearance settings are supposed to work, and eventually, on the "Run CLion for the first time" page, I find this unassuming image:

You might already have a suspicion where this is going from that image, and I do too at this point.

So to check if my idea is correct, I desperately search for the CLion configuration files. The location doesn't seem to be well documented on the internet, but I find them in ~/.config/JetBrains/CLion2023.2/options. Makes sense. Quickly grep for "Theme" in that folder, looks like the theme settings are in laf.xml.

Huh that is interesting, it still has the autodetect setting set to true.

Changing it to "false" manually fixes the issue. And I'm laughing out with my head in my hands at this being the actual fix.

To explain, what must have happened is, when dropping support for autodetect on Linux, JetBrains removed the "Sync with OS" checkbox, but forgot to change the setting to false for Linux users. So now, if it's still applied from before the feature was dropped, it doesn't do anything substantial, but the code to grey out the actual theme setting is still in effect!

How can you serialize and deserialize Java objects for frontend-backend communication?

1. What’s Java Serialization and Deserialization All About?  

So, how do you handle communication between the frontend and backend in Java? It’s all about turning Java objects into a byte stream (that’s serialization) and then back into objects (deserialization). This makes it easy to exchange data between different parts of your app. The Serializable interface in Java is key for this, as it helps keep the state of objects intact. If you’re taking a Java course in Coimbatore, you’ll get to work on this a lot. Serialization is super important for things like APIs and managing sessions. For Java backend developers, it's a must-know.

2. Why Is Serialization Important Nowadays?  

When it comes to Java and modern web apps, we often use JSON or XML for serialized data. Libraries like Jackson and Gson make it easy to convert Java objects to JSON and vice versa. These formats are great for frontend and make communication smoother. If you study Java in Coimbatore, you'll learn how serialization fits into REST APIs. Good serialization helps keep your app performing well and your data secure while also supporting setups like microservices.

3. What’s the Serializable Interface?  

The Serializable interface is a simple marker in Java telling the system which objects can be serialized. If you get this concept down, it really helps answer how to serialize and deserialize Java objects for frontend-backend communication. By using this interface, you can easily save and send Java objects. Students in a Java Full Stack Developer Course in Coimbatore learn how to manage complex object structures and deal with transient variables to keep things secure and fast.

4. Tools and Libraries for Serialization in Java  

To serialize objects well, developers often rely on libraries like Jackson and Gson, along with Java’s ObjectOutputStream. These are essential when you’re trying to serialize Java objects for frontend-backend communication. With these tools, turning Java objects into JSON or XML is a breeze. In Java courses in Coimbatore, learners work with these tools on real projects, and they offer options for customizing how data is serialized and handling errors more smoothly.

5. Deserialization and Keeping Things Secure  

Deserialization is about getting objects back from a byte stream, but you've got to do this carefully. To serialize and deserialize Java objects safely, you need to check the source and structure of incoming data. Training in Coimbatore covers secure deserialization practices so you can avoid issues like remote code execution. Sticking to trusted libraries and validating input helps keep your app safe from attacks.

6. Syncing Frontend and Backend  

Getting the frontend and backend in sync relies heavily on good serialization methods. For instance, if the Java backend sends data as JSON, the frontend—often built with React or Angular—needs to handle it right. This is a key part of learning how to serialize and deserialize Java objects for frontend-backend communication. In Java Full Stack Developer Courses in Coimbatore, students work on apps that require this skill.

7. Dealing with Complex Objects and Nested Data  

A big challenge is when you have to serialize complex or nested objects. When figuring out how to serialize and deserialize Java objects for frontend-backend communication, you need to manage object references and cycles well. Libraries like Jackson can help flatten or deeply serialize data structures. Courses in Coimbatore focus on real-world data models to give you practical experience.

8. Making Serialization Efficient  

Efficient serialization cuts down on network delays and boosts app performance. Students in Java training in Coimbatore learn how to make serialization better by skipping unnecessary fields and using binary formats like Protocol Buffers. Balancing speed, readability, and security is the key to good serialization.

9. Real-Life Examples of Java Serialization  

Things like login sessions, chat apps, and shopping carts all depend on serialized objects. To really understand how to serialize and deserialize Java objects for frontend-backend communication, you need to know about the real-time data demands. In a Java Full Stack Developer Course in Coimbatore, you’ll get to simulate these kinds of projects for hands-on experience.

10. Wrapping It Up: Getting Good at Serialization  

So how should you go about learning how to serialize and deserialize Java objects? The right training, practice, and tools matter. Knowing how to map objects and secure deserialized data is crucial for full-stack devs. If you're keen to master these skills, check out a Java course or a Java Full Stack Developer Course in Coimbatore. With practical training and real projects, Xplore IT Corp can set you on the right path for a career in backend development.

FAQs  

1. What’s Java serialization for?  

Serialization is for turning objects into a byte stream so they can be stored, shared, or cached.  

2. What are the risks with deserialization?  

If deserialization is done incorrectly, it can lead to vulnerabilities like remote code execution.  

3. Can every Java object be serialized?  

Only objects that implement the Serializable interface can be serialized. Certain objects, like threads or sockets, can’t be.  

4. Why use JSON for communication between frontend and backend?  

JSON is lightweight, easy to read, and can be easily used with JavaScript, making it perfect for web apps.  

5. Which course helps with Java serialization skills?  

The Java Full Stack Developer Course in Coimbatore at Xplore IT Corp offers great training on serialization and backend integration.

IntelliJ IDEA 2025.1 EAP Is Open!  | The IntelliJ IDEA Blog

Some nice stuff, including fully automated Spring bean creation.

Project update

Approaching the half-year mark for the open-source coding challenge I started in June. Here are current statistics:

+ 34K lines of Java (up from 29K lines on 11 November)

+ of those, 12K are tests or examples (up from 8K)

+ 19K lines of C++ (up from 17K)

These days I'm mostly translating the JoltPhysics "samples" application from C++ into Java. I use translation to uncover important functionality that my JVM bindings haven't exposed yet. It's slow, repetitive work, but there are occasional opportunities for problem solving. I have a high tolerance for repetitive work, but it's not unlimited. Soon I'll need a break from the current grind.

I recently imported my project into IntelliJ's IDEA development environment. I use Apache NetBeans for most of my software development, but IDEA has an automatic code-inspection tool I like to use occasionally. The tool uncovered dozens of problems I was glad to fix. However, it also reported thousands of false positives---things it thinks are problems but I do not. My experience with automated inspection tools is that they are invaluable on occasion, but for a given project, their benefit/cost ratio declines rapidly after first use.

Cucumber is a widely-used tool for Behavior-Driven Development (BDD) that helps teams collaborate on creating automated acceptance tests. It uses a plain-text language called Gherkin to describe the behavior of software, making it easier for non-technical stakeholders to understand. IntelliJ IDEA, a powerful Integrated Development Environment (IDE) by JetBrains, supports various plugins that enhance its functionality, including the Cucumber plugin.
