10 Things Java Programmer should learn in 2020

1. DevOps (Docker and Jenkins)

This is one area where I am seeing a lot of traction last year as more

and more companies are moving into DevOps and adopting continuous

integration and deployment.

DevOps is very vast and you need to learn a lot of tools and

principles and that's what overwhelm many developers but you don't need

to worry. I have shared a DevOps RoadMap which you can follow to learn and master DevOps at your own speed.

This means if you are an experienced Java programmer with a passion

for managing the environment, automation and improving overall

structure, you can become a DevOps Engineer.

If you are looking for some awesome resources then Master Jenkins CI For DevOps and Developers is a great course to start with, particularly for Java developers, and if you want to learn more, this DevOps Roadmap is perfect companion.

2. Git

Git and Github have been around some time and while I have used Git in past with Eclipse, but I am yet to become master of Git on the command line, and I am not alone

Many programmers haven't mastered Git yet? Simply because they didn't need it yet as there code might be in SVN or CVS.

I have also occasionally downloaded projects from Github and run from Eclipse but still far from being expert with Git commands, particularly reverting changes and handling errors.

Since now most of the companies are migrating their projects from

SVN, CVS to Git, its high time to learn and master Git.

I have recently purchased the Git Complete: The definitive, step-by-step guide to Git from Udemy on their last 10$ sale and this would be the first item to complete in 2020.

If you are in the same boat and want to learn or improve your Git

skill in 2020, do check out that course from Udemy, it's very handy.

3. Java 9,10,11,12 or maybe 13

As I said, I am still learning Java 8 and many Java developers too. I will also spend some time learning new features of Java 9, Java 10, Java 11, and Java 12 in 2020 but for me, Java 8 is still a priority, until I moved to Java 11 which is another LTS release.

The JDK 9 brings a lot of goodies in terms of modules, Jigsaw, Reactive Streams, Process API, HTTP2 client, JShell, and API improvements like collection factory methods and I am really looking forward to learning them at the earliest opportunity.

Similarly, JDK 10 brings var to give you a flavor of dynamic typing and some GC improvement.

In the last Udemy 10$ sale, I have purchased a host of courses and one of them is The Complete Java MasterClass, which is updated for Java 12 and I am looking forward to starting my Java 12 journey with that.

Btw, if you have yet to start with JDK 8 then here is my list of favorite Java 8 tutorials and courses which you can free of cost: 10 best tutorial to learn Java 8.

4. Spring Framework 5

I have been hearing about some new features like reactive programming

model on Spring 5, adoption of recent Java features, some unit testing

improvement etc but I have yet to try that.

Anyway, I have already started learning Spring 5.0 by following Spring 5. 0: Beginner to Guru and will keep the momentum going in 2020 . If you use Spring, probably it's the best time to learn Spring 5.0.

If you like books, you can also check out this list of advanced Spring Books for Java developers from Manning and Packt Publications.

5.Unit testing

Another area which I want to improve in the coming year. There are a lot of new framework and tools available for Java programmers to unit test and integration test their application like Mockito and PowerMock for mocking objects, Robot Framework, and Cucumber for automated integration test and of course the new and shining JUnit 5 library.

There is plenty of stuff to learn on this front. If you can invest

some time upgrading your unit testing skill, not only your coding skill

will improve but also you will become a more professional developer,

which every company looks form. To start with, you can check out JUnit and Mockito Crash Course from Udemy.

And, if you need more choices, you can check these top 5 JUnit and Mockito courses for some inspiration.

6. RESTful Web Service

One more thing I want to keep improving in 2020 is my knowledge about

writing REST API and implementing secure and scalable RESTful Web

Service in Java using Spring.

This is one skill which is highly desirable in the Java world and there are not many people who know both Java and REST well.

If you are also in the same boat and want to learn how to develop RESTful Web Service using Spring, The REST of Spring MasterClass from Eugen Paraschiv is a good starting point.

7. Spring Security 5.0

This is the third major upgrade on Spring Eco-System. The 5th version of

popular security framework has several bug fixes and a major OAuth 2

module, which you just can't miss.

This is another priority Item for me in 2020 along with Spring 5.0 framework stuff. Thankfully Eugen has updated his best selling course Learn with Spring Security to include 5.0 features and added a separate module for OAuth 2.0., probably the best material to learn Spring Security 5.0 at this moment.

8. Spring Boot 2

The Spring Boot framework also has a new release Spring Boot 2. If I get

sometime after all these goals this year then I will spend some time

learning Spring Boot 2.

9. Angular 2+ or React JS

These two JavaScript framework has completely changed how you develop web applications.

As a Java developer, I have used Servlet, JSP, and jQuery at client side but haven't yet tried my hand with Angular or React.

In 2020, one of my goals is to learn Angular and I will be starting my journey with Udemy's Angular 7- The Complete Guide. If you are in the same boat then you can also take a look at that course, it's very handy.

10. Android

If you don't know how to write Android Apps in 2020 then you are lacking

something. Mobile is one of the best platforms to reach a large number

of people and Android is probably the most popular platform to write

mobile applications.

Even though I know Android basics, I have yet to publish any Android

apps, maybe 2020 will change that. If you want to learn Android in 2020,

you can check The Complete Android N Developer Course, one of the better course to learn Android.

If you need more choices then I have also shortlisted some Android online courses to refresh my knowledge and get to the next level. If you are also in the same boat then you may find them useful as well.

11. Apache Spark and Kafka

One more thing I want to keeping exploring in depth in 2020 is the Big Data space, and particularly Apache Spark and Apache Kafka framework.

I am not sure if I will get time to look other Big data technologies

but its seriously good stuff and along with DevOps and Machine Learning,

Big Data is probably the hottest technology at this moment.

If you also want to learn Big data in 2020, you can check The Ultimate Hands-On Hadoop --- Tame your Big Data! course.

That's all about what Java developers should learn in 2020. As I have said, Technology changes with rapid speed and the biggest challenge for programmers are to keep themselves up-to-date.

Apart from this list, there are plenty of other stuff which you can

look-up in new year e.g. learning a new programming language like Kotlin

but for me, I will be more than happy if I can achieve these goals in

2020.[Source]-1. DevOps (Docker and Jenkins)

This is one area where I am seeing a lot of traction last year as more

Hybrid Apps Online training in India

Hybrid Apps online training in India, Hybrid Apps online training classes in India - Webtrackker is one of the best Ionic apps training in India, Ionic apps training in India with 100% placement support, Delhi or hybrid apps training institutes in India with 100% placement support. In this Hybrid Mobile App Development with Ionic training course, expert will teach you how to use the Ionic framework to create hybrid mobile applications. This course is designed for the absolute beginner, meaning no experience with mobile app development is required.You will start by learning how to build apps with the Ionic framework. From there, Expert will teach you how to build a to do application, a weather app, and a national park guide app. Hybrid Apps online training in India :This video tutorial will then teach you how to debug and test Ionic applications, including working with emulators, testing on iOS and Android devices, and using Ionic view. Finally, you will finish up your Ionic application by preparing it for submission, code signing for iOS and Android, and generating app icons and splash screens. Hybrid mobile apps are like any other apps you’ll find on your phone. They install on your device. You can find them in app stores. With them, you can play games, engage your friends through social media, take photos, track your health, and much more.

Like the websites on the internet, hybrid mobile apps are built with a combination of web technologies like HTML, CSS, and JavaScript. The key difference is that hybrid apps are hosted inside a native application that utilizes a mobile platform’s . You can think of the WebView as a chrome less browser window that’s typically configured to run fullscreen. This enables them to access device capabilities such as the accelerometer, camera, contacts, and more. These are capabilities that are often restricted to access from inside mobile browsers. Furthermore, hybrid mobile apps can include native UI elements in situations where necessary, as evidenced by Webtrackker approach towards hybrid mobile app development.

It can be very difficult to tell how a mobile application is built. Hybrid mobile applications are no different. A well-written hybrid app shouldn’t look or behave any differently than its native equivalent. More importantly, users don’t care either way. They simply want an application that works well. Trying to figure out if a mobile application is hybrid or native is like trying to differentiate rare grape varieties of wine. Unless you’re a sommelier or someone who really cares about it, it’s not terribly important. What matters is that the wine tastes good. The same can be said for hybrid mobile applications; so long as the application does what it’s supposed to do, who really cares how it was built? This point is underscored through an experiment we conducted where we wanted to see if people could tell the difference between a native application and a hybrid application:

15 Things Java Developer Should Learn in 2020

1. DevOps

This is one area where I am seeing a lot of traction last year as more and more companies are moving into DevOps and adopting continuous integration and deployment.

DevOps is very vast and you need to learn a lot of tools and principles and that’s what overwhelm many developers but you don’t need to worry. I have shared a DevOps RoadMap which you can follow to learn and master DevOps at your own speed.

This means if you are an experienced Java programmer with a passion for managing the environment, automation and improving overall structure, you can become a DevOps Engineer.

If you are looking for some awesome resources then Jenkins, From Zero to Hero: Become a DevOps Jenkins Master is a great course to start with, particularly for Java developers.

2. Git

Git and Github have been around some time and while I have used Git in past with Eclipse, but I am yet to become a master of Git on the command line.

Why I haven’t mastered Git so far? Simply because I didn’t need it yet. I have occasionally downloaded projects from Github and run from Eclipse but I am still not so great with Git commands, particularly reverting changes and handling errors.

Since now most of the companies are migrating their projects from SVN, CVS to Git, its high time to learn and master Git. I have recently purchased the Git Complete: The definitive, step-by-step guide to Git from Udemy on their last 10$ sale and this would be the first item to complete in 2020.

If you are in the same boat and want to learn or improve your Git skill in 2020, do check out that course from Udemy, it’s very handy.

3. Java 9–14

As I said, I am still learning Java 8 and many Java developers too. I will also spend some time learning new features of Java 9, Java 10, Java 11 in 2020 but for me, Java 8 is still a priority, until I moved to Java 11 which is another LTS release.

Similarly, JDK 10 brings var to give you a flavor of dynamic typing and some GC improvement.

In the last Udemy 10$ sale, I have purchased a host of courses and one of them is The Complete Java MasterClass, which is updated for Java 11 and I am looking forward to starting my Java 11 journey with that.

Btw, if you have yet to start with JDK 8 then here is my list of favorite Java 8 tutorials and courses which you can free of cost: 10 best tutorial to learn Java 8.

If you need a list of courses to learn new features from Java 9 to Java 13 then you can take a look at this list of courses to learn new features from JDK 9 to JDK 13.

4. Spring Framework 5

I have been hearing about some new features like reactive programming model on Spring 5, adoption of recent Java features, some unit testing improvement, etc but I have yet to try that.

Anyway, I have already started learning Spring 5.0 by following Spring 5. 0: Beginner to Guru and will keep the momentum going in 2020. If you use Spring, probably it’s the best time to learn Spring 5.0.

If you like books, you can also check out this list of advanced Spring Books for Java developers from Manning and Packt_Pub

5. Unit testing

Another area which I want to improve in the coming year. There are a lot of new frameworks and tools available for Java programmers to unit test and integration test their application e.g. Mockito and PowerMock for mocking objects, Robot Framework, and Cucumber for automated integration test and of course the new and shining JUnit 5 library.

There is plenty of stuff to learn on this front. If you can invest some time upgrading your unit testing skill, not only your coding skill will improve but also you will become a more professional developer, which every company looks form. To start with, you can check out the JUnit and Mockito Crash Course from Udemy.

6. RESTful Web Service

One more thing I want to keep improving in 2020 is my knowledge about writing REST API and implementing secure and scalable RESTful Web Service in Java using Spring.

This is one skill which is highly desirable in the Java world and there are not many people who know both Java and REST well.

If you are also in the same boat and want to learn how to develop RESTful Web Service using Spring, The REST of Spring MasterClass from Eugen Paraschiv is a good starting point.

7. Spring Security 5.0

This is the third major upgrade on Spring Eco-System. The 5th version of the popular security framework has several bug fixes and a major OAuth 2 module, which you just can’t miss.

This is another priority Item for me in 2020 along with Spring 5.0 framework stuff.

Thankfully Eugen has updated his best selling course Learn with Spring Security to include 5.0 features and added a separate module for OAuth 2.0., probably the best material to learn Spring Security 5.0 at this moment.

8. Spring Boot 2

The Spring Boot framework also has a new release Spring Boot 2. If I get sometime after all these goals this year then I will spend some time learning Spring Boot 2.

If you also want to learn Spring Boot 2, you can check out this free Spring boot course from Udemy for a quick start.

If you need more choices then you can also check this list of top Spring boot courses for Java developers to learn in 2020.

9. Angular 2+ or React JS

These two JavaScript framework has completely changed how you develop web applications.

As a Java developer, I have used Servlet, JSP, and jQuery at the client side but haven’t yet tried my hand with Angular or React.

In 2020, one of my goals is to learn Angular and I will be starting my journey with Udemy’s Angular 9 - The Complete Guide. If you are in the same boat then you can also take a look at that course, it’s very handy.

10. Android

If you don’t know how to write Android Apps in 2020 then you are lacking something. Mobile is one of the best platforms to reach a large number of people and Android is probably the most popular platform to write mobile applications.

Even though I know Android basics, I have yet to publish any Android apps, maybe 2020 will change that. If you want to learn Android in 2020, you can check The Complete Android N Developer Course, one of the better course to learn Android.

11. Apache Spark and Kafka

One more thing I want to keeping exploring in-depth in 2020 is the Big Data space, and particularly Apache Spark and Apache Kafka framework.

I am not sure if I will get time to look at other Big data technologies but its seriously good stuff and along with DevOps and Machine Learning, Big Data is probably the hottest technology at this moment.

If you also want to learn Big data in 2020, you can check The Ultimate Hands-On Hadoop — Tame your Big Data! course.

If you need more choices you can also check my list of shortlisted courses to learn Apache Spark for Java developers from Udemy and Pluralsight.

12. Docker and Kubernetes

You’ve probably heard the buzz around Docker and Kubernetes and the impact it has on DevOps teams. You may have at first thought, “ahh, yet another new technology I need to learn”, but I will say that Docker is not just another technology but its truly a game-changer.

Along with Kubernetes, It’s one of the most important tools that you can learn and will stay with you throughout your entire career.

Nowadays, Docker and Kubernetes are used by almost every development team, whether it’s a large enterprise or a small startup. It’s safe to say that if you’re entering the workforce now, you’ll most likely brush up against Docker at some point.

In short, whether you are a junior Java developer or an experienced veteran of several years of experience, Having Docker and Kubernetes knowledge is essential for your career progression and job change. If you have already realized the importance of Kubernetes and looking to learn Kubernetes in 2020 then Docker and Kubernetes: The Complete Guide by Stephen Grider on Udemy is an excellent course to start with.

If you prefer free resources, like free online courses, then you can also check out this list of free Docker and Kubernetes courses for Java developers to start your journey.

13. Microservices

Microservices are nothing but an extension of RESTful web services with the main objective being to break up your code into small, distributed, and independent services for better development, deployment, and management.

The Microservices architecture is ideal for the public cloud, with its focus on elastic scaling with on-demand resources. However, it does require thoughtful design and a significant amount of preparation.

Fortunately, Spring Boot and Spring Cloud simplify your microservice applications by providing common features and allowing you to focus on business logic by abstracting away details required for cloud-based development.

If you also want to learn Spring Boot 2 and Microservice in 2020 then you can also check out this Master Microservices with Spring Boot and Spring Cloud from Udemy for a quick start.

If you need more choices, then you can also check this list of top Spring boot courses for Java developers to learn in 2020.

14. Cloud (AWS)

Apart from containers, Cloud is another thing which I think every Software developer and Data Scientist should learn in 2020. Companies of all sizes and domains are now shifting their environments into Cloud for cost-saving and better scalability, which means sooner or later, you need to work with cloud-native applications.

Learning Cloud platforms like Amazon Web Service (AWS), Google Cloud Platform (GCP) or Microsoft Azure will take you one step ahead of your competitors not only in your current job but also in the next post. You don’t need to learn all of them, and in fact, learning one means you will have a fair idea about others.

To start with, I suggest you learn AWS as it is the most popular and most mature cloud platform and there is a strong demand of developers and system admins with AWS knowledge if you need a resource then I recommend the AWS Certified Solutions Architect — Associate 2020 course by Ryan Kroonenburg the Cloud Guru. It will not only help you learn AWS in-depth but also prepare you for AWS certification.

If you need free courses to learn AWS online, you can also check this list of best free AWS courses for beginners to start with.

15. Concurrency

Concurrency is one of the skills which separates an average developer from a good programmer. You should not only have an in-depth understanding of fundamental concepts like Thread, Runnable, Object locking, and Synchronization, but you should also be familiar with concepts like deadlock, livelock, race conditions, and how to deal with them.

You should also learn about advanced Java concepts like synchronizers added on Java 5 and subsequent version, I mean CyclicBarrier, CountDownLatch, Phaser, and CompleteableFuture, etc., along with Futures and how to perform the async operation in Java.

I know, it’s a lot of stuff, and that’s why I suggest you join an in-depth course like Java Concurrency in Practice bundle from Heinz Kabutz, a Java Champion, and authority when it comes to concurrency and design patterns. This course is a bit expensive, but you will learn a lot more concepts in-depth, which makes it completely worth your time and money.

On the other hand, if the price is an issue, you can also check this Udemy course to Efficient Java Multithreading with Executors, which won’t cost you more than $10 if you get it on Udemy flash sales which happens every month. This is also an excellent course to learn Java concurrency and multithreading in Java.

That’s all about what to learn in 2020. As I have said, Technology changes with rapid speed and the biggest challenge for programmers are to keep themselves up-to-date.

Apart from this list, there is plenty of other stuff that you can look-up in the new year like learning a new programming language like Kotlin but for me, I will be more than happy if I can achieve these goals in 2020.[Source]-https://medium.com/swlh/10-things-java-developer-should-learn-in-2019-5e0cf388e07f

15 Things Java Developer Should Learn in 2020

Hello guys, another year is approaching and it’s a good time to look back and retrospect what you have achieved last year and what you could have done better.

This will help you to create your goals for 2020. As a programmer, your biggest challenge is to keep yourself up-to-date. Technology changes very fast and you will see a new version of your favorite programming language and framework coming to every year.

For Java developers, last, a couple of years has brought plentiful changes and posed a challenge with keeping up-to-date with a new Java version every 6 months, Spring 5, Spring Security 5, and Spring Boot 2 etc.

When I started 2019, I thought Java 9 was new and before I could finish learning Java 9 completely, Java 10 and Java 11 was already out.

So, they came really fast but came with a lot of interesting features like var with local variables, API enhancements, GC improvement, Thread Local handshake and many more. I have documented them here and I am really excited to use those in 2020.

Same goes with Spring framework and Spring Security, I didn’t know all the changes on Spring 4.0 and Spring Security 4.0, my project was still using Spring Security 3.1 and boom we now we have version 5.0 for both Spring and Spring security.

My learning speed has slowed down a little bit in last a couple of years and I haven’t managed to keep myself up-to-date with the latest and greatest like I am yet to get comfortable with Git, JavaScript frameworks like Angular and React, latest changes on unit and integration testing space and new version of popular framework e.g. Spring, Spring Security, and Spring Boot.

I managed to catch up many of those last years, hence, 2020 will be all about consolidation and keeping myself up-to-date with things which matters most on the technology side, improving my toolset chain and exploring the DevOps landscape

The Good and the Bad of Java Programming

There are not many technologies that can brag about staying relevant for more than 20 years. But this year, Java was voted the 5th most popular technology, eclipsed only by undisputed leaders JavaScript, HTML, CSS, and SQL. While it’s 18th on the list of most loved in the same StackOverflow survey, it’s also down the list in its most-dreaded ranking. Today, we unravel the many successes and challenges of Java — the time-honored technology with the iconic steaming cup-of-coffee logo, a language near and dear to many programmers' hearts.

What Is Java Programming: History and Impact

Java is a general-purpose programming language that follows the object-oriented programming paradigm and the "Write Once, Run Anywhere" approach. Java is used for desktop, web, mobile, and enterprise applications. You can out find out more about it here:

Java downloads

Java documentation

Oracle Java community

JavaWorld — popular portal for all things Java

JavaRanch — forums for Java developers

Java is not only a language but an ecosystem of tools covering almost everything you may need for Java development. This includes:

Java Development Kit (JDK) – with that and a standard Notebook app, you can write and run/compile Java code.

Java Runtime Environment (JRE) — this is a software distribution tool containing a stand-alone Java Virtual Machine, the Java standard library (Java Class Library), and a configuration tool.

Integrated Development Environment (IDE) — this is a set of tools that help you run, edit, and compile your code. IntelliJ IDEA, Eclipse, and NetBeans are the most popular amongst them.

Java can be found anywhere you look. It’s the primary language for Android development. You will find it in web applications, governmental websites, and big data technologies, such as Hadoop and Apache Storm. And, it’s also a classic choice for scientific projects, especially natural language processing. Java was dominating mobile even in pre-smartphone days. The first mobile games in the early 2000s were mostly made in Java. So, it’s fair to say that Java, thanks to its long history, has earned its place in the Programming Hall of Fame. TIOBE index, one of the most reputable programming rankings in the world, uses search engine results for calculation. Despite the growing popularity of Go and Python, Java has remained at the top of the list for more than a decade.

TIOBE Index data as of August, 2018

It all started in the early 1990s, when the Sun Microsystems team began developing a better version of C++ that was easily portable, novice-friendly, and enabled with automated memory management. The research resulted in the creation of an altogether new language, and the name was picked from dozens of others yelled out in the meeting room. Today, the logo of a steaming coffee cup is the silent, universally recognizable symbol of programming. And, it’s no longer clear what came first — the programmers’ obsession with caffeine or associations with Java, which are now synonymous with coffee.

the evolution of java logosThese are just some of the changes Java introduced to the programming world:

Flexibility. Java proved that C’s procedural, manually-allocated, and platform-dependent code wasn’t the be-all and end-all. Thanks to Java, more people started adopting object-oriented programming, a commonly-accepted method today.

Applets. In the years before JavaScript, Java introduced applets, small web programs that provided interactive elements, especially useful for visualization and teaching. Although they were never used for anything more than simple animations, it’s what captured the attention of many programmers and paved the road for the development of HTML5, Flash, and, of course, JavaScript.

Test-driven development. With Java, TDD was no longer an experimental practice, but the standard way to develop software. The introduction of JUnit in 2000 is considered one of Java’s biggest contributions.

Benefits of Programming in Java

Though no longer the only officially supported language for Android development and, of course, far from the only choice for web programming, Java keeps pace with the alternatives. And, since that’s not only thanks to its respectable age, let’s explore some of the advantages Java has to offer.

Object-Oriented Programming

Java embraces object-oriented programming (OOP), a coding concept in which you not only define the type of data and its structure, but also the set of functions applied to it. This way, your data structure becomes an object that can now be manipulated to create relationships between different objects.

In contrast to another approach — procedural programming — where you have to follow a sequence of instructions using variables and functions, OOP allows you to group these variables and functions by context, thus, labeling them and referring to functions in the context of each specific object.

Comparing procedural programming and object-oriented programming

Why Is OOP an Advantage?

You can easily reuse objects in other programs

It prevents errors by having objects hide some information that shouldn’t be easily accessed

It makes programs more organized and pre-planned, even the bigger ones

It offers simple maintenance and legacy code modernization

High-Level Language With Simple Syntax and a Mild Learning Curve

Java is a high-level language, meaning that it closely resembles the human language. In contrast to low-level languages that resemble machine code, high-level languages have to be converted using compilers or interpreters. This simplifies development, making the language easier to write, read, and maintain.

Writing Hello World in Java

Java derived its syntax (set of rules and structure used by programmers) from C++, which is why you will notice that it closely resembles C code. However, it’s much simpler, allowing beginners to learn the technology faster and code more effectively to achieve specific results.

Java may not be as beginner-friendly as Python, but any developer with a basic understanding of frameworks, packages, classes, and objects can grasp it pretty soon. It’s straightforward, strongly-typed, and has very strict expectations that soon help guide your thinking in the right direction. Besides, tons of free online tutorials and courses won’t keep a novice helpless.

Standard for Enterprise Computing

Enterprise applications are Java’s greatest asset. It started back in the 90s when organizations began looking for robust programming tools that weren’t C. Java supports a plethora of libraries, which are the building blocks of any enterprise system, that help developers create any function a company may need. The vast talent pool also helps. Java is a language used as an introduction to computer programming in most schools and universities. Besides, its integration capabilities are impressive, as most of the hosting providers support Java. Last but not least, Java is comparatively cheap to maintain, since you don’t have to depend on a specific hardware infrastructure and can run your servers on any type of machine you may have.

Shortage of Security Risks

You may encounter the notion that Java is a secure language, but that’s not entirely true. The language itself doesn’t protect you from vulnerabilities, but some of its features can save you from common security flaws. First, compared to C, Java doesn’t have pointers. A pointer is an object that stores the memory address of another value that can cause unauthorized access to memory. Second, it has a Security Manager, a security policy created for each application where you can specify access rules. This allows you to run Java applications in a “sandbox,” eliminating risks of harm.

Platform-Independency (Write Once, Run Anywhere)

Write Once Run Anywhere (WORA) is a popular programming catchphrase introduced by Sun Microsystems to describe Java’s cross-platform capabilities. It meant you could create a Java program on, let’s say, Windows, compile it to bytecode, and run the application on any other platform that supports a Java Virtual Machine (JVM). In this case, a JVM serves as an abstraction level between the code and the hardware.

How WORA approach works in Java

All major operating systems, including Windows, Mac OS, and Linux, support the JVM. And, unless you’re writing a program that relies mostly on platform-specific features and UI, you can share — maybe not all — a big chunk of bytecode.

Distributed Language for Easy Remote Collaboration

Java was designed as a distributed language meaning that it has an integrated mechanism for sharing data and programs among multiple computers for improved performance and efficiency.

Distributed computing vs parallel computing

Unlike other languages, where you have to use external APIs for distribution, Java offers this technology at its core. Java-specific methodology for distributed computing is called Remote Method Invocation (RMI). Using RMI allows you to bring all Java benefits, such as security, platform-independence, and object-oriented programming, to distributed computing. Apart from that, it also supports Socket Programming and the distribution methodology of CORBA for sharing objects between programs written in different languages.

Automatic Memory Management

Java developers don’t have to worry about manually writing code for memory management tasks, thanks to automatic memory management (AMM), also used in the Swift programming language, and garbage collection, an application that automatically handles allocation and deallocation of memory. What exactly does it mean?

A program’s effectiveness is directly linked to memory. And, memory is limited. By using languages with manual management, developers risk forgetting to allocate memory, resulting in increased memory footprint and lagging. A garbage collector can locate objects that are no longer referenced by your program and remove them. Despite the fact that it affects your program’s CPU, you can reduce or prevent it with smart optimization and tuning.

Multithreading

In programming, a thread is the smallest unit of processing. To maximize utilization of CPU time, Java allows you to run these threads simultaneously — in a process called multithreading.

Threads share the same memory area, so switching between them takes little time. They are also independent, so if one thread faces exception, it doesn’t affect other threads. This is especially useful for gaming and animation-heavy programs.

Stability and Massive Community

Java has survived to a respectable age, thanks to the community, Oracle’s support, and the cornucopia of applications and languages that keep running on JVM. Besides, new versions of Java are regularly released with new, interesting features.

Java’s developer community is also unmatched. About 45 percent of StackOverflow 2018 survey respondents use Java. It has an extremely large ecosystem of well-tested libraries and frameworks for any use case. Java is most likely to be one of the first languages beginning developers encounter in their studies, as there are 1000+ Java-related courses on Udemy and 300+ on Coursera.

Drawbacks of Programming in Java

Here are the cons you want to know before writing your next project in Java.

Paid Commercial LicenseOracle recently announced that they will start charging Java SE 8 for “business, commercial, or production” use starting in 2019. To get all new updates and bug fixes, you’ll need to pay by the number of users or per processor.

Today, the current version of Java is free and available for redistribution for general purpose computing. To prepare for the change, each company has to evaluate how much of Java they use and seek an alternative technology if the price upgrade promises to be too painful.

Poor Performance

Any high-level language has to deal with poor performance due to the compilation and abstraction level of a virtual machine. However, it’s not the only reason for Java’s often criticized speed. Take garbage collector, a useful feature that unfortunately can lead to significant performance problems if it takes more than 20 percent of CPU time. Bad caching configuration can also cause excessive memory and garbage collection usage. There are also thread deadlocks that happen when several threads are trying to access the same resource, and — every Java developer’s nightmare — out-of-memory errors. Although each of these problems can be prevented with skillful planning, they do add up and can cause different volumes of damage.

Far From a Native Look and Feel on the Desktop

To create a program’s graphical user interface (GUI), developers use different language-specific tools. Thus, for Android apps, there’s Android Studio that helps create apps that look and feel native. However, when it comes to desktop UI, Java noticeably lacks.

There are a few GUI builders Java programmers can choose from: Swing, SWT, JavaFX, JSF being the most popular. Swing is an old-but-reliable, cross-platform, and already-integrated GUI builder with various Java IDEs, including Eclipse and NetBeans. But, unless you’re using templates, you’ll notice interface inconsistencies. SWT uses native components, but it’s not suitable for complicated UI. JavaFX is clean and modern-looking, but it’s not very mature. Overall, choosing a good fit for your GUI building on Java requires additional research.

Verbose and Complex Code

When the code is verbose, it means it uses too many words. While it may seem an advantage when you’re trying to understand the language, long, over-complicated sentences make code less readable and scannable. By trying to emulate English, many high-level languages tend to make too much noise. Java, created to tone down the unapproachable C++, forces programmers to type exactly what they mean, which makes the language more transparent to non-experts but, unfortunately, less compact.

If we compare Java to its rival Python, we can see how clear Python code appears — it doesn’t require semicolons and uses “and,” “or,” and “not” as operators instead of Java’s “&&,” “||,” and “!” Generally, Python has fewer bells and whistles, such as parentheses or curly braces.

Conclusion: Where Is Java Used?

Most organizations use Java in one way or another. A wide range of use cases makes these applications almost invisible, which is why the question “where to use Java” is often raised. To finish our overview, let’s see which domains can be covered by Java:

Android apps. Despite Kotlin’s invasive growth, Java is still the de facto language for Android apps, which automatically turns a big pool of Java developers into Android programmers. While Android uses Android SDK instead of JDK, the code is still written in Java.

Software products. Apart from already-mentioned Hadoop and Apache Storm, Java was used to create Eclipse, OpenOffice, Gmail, Atlassian, and more.

Finance programs. Being one of the most demanded language skills in the financial industry, Java is used both on the server- and client-side to build reliable, fast, and simple websites. It’s also a preferred language for data simulations and modeling.

Point of sale systems. Many businesses use Java to create PoS systems, as they usually require platform-independency and a vast talent pool.

Trading applications. Murex, a popular bank management program for front and back connectivity, is written in Java.

Big data programs. Hadoop is written in Java. Scala, Kafka, and Spark use JVM. Also, Java gives you access to tons of tried-and-tested libraries, debuggers, and monitoring tools.[Source]-https://dzone.com/articles/the-good-and-the-bad-of-java-programming
