10 Things Java Developer Should Learn in 2022

Things Java Developer Should Learn in 2022

This will assist you in developing your objectives for 2022. The most difficult aspect of becoming a coder is staying current. Technology advances at a breakneck pace, and every year, a new version of your favourite programming language and framework will be released.

For Java developers, the previous several years have introduced a slew of new features and challenges, such as a new Java version every six months, Spring 5, Spring Security 5, and Spring Boot 2, to name a few.

I believed Java 11 was fresh when I started this year, however before I could finish studying Java 11, Java 16 and Java 17 were already available.

The same can be said for the Spring framework and Spring Security; I wasn’t aware of all the changes in Spring 5.0 and Spring Security 4.0, and my project was still using Spring Security 3.1, but now both Spring and Spring Security are at version 6.0.

During last few year, my learning rate has started to slow a little and I’ve never been able to keep up with the latest and greatest, such as Git, JavaScript frameworks like Angularjs, latest changes in the unit and integration and system testing space, and new versions of popular frameworks like Spring, Spring Security, and Spring Boot.

I was able to catch up in many of those previous years, so 2022 will be all about consolidation and staying up with the most important technological developments, as well as strengthening my toolchain and investigating the DevOps environment.

What Java Programmers should learn in 2022:

1. DevOps:

This is an area where I saw a lot of traction last year, with more and more firms embracing DevOps and continuous integration and deployment.

DevOps is large, and you’ll need to master a lot of tools and techniques, which might be overwhelming for some engineers, but don’t fear. I’ve put together a DevOps RoadMap for you to use to study and master DevOps at your own pace.

You may become a DevOps Engineer if you are an experienced Java programmer with a love for controlling the environment, automating processes, and enhancing overall structure.

Jenkins, From Zero to Hero: Become a DevOps Jenkins Master is an excellent place to start if you’re searching for some amazing materials, especially for Java engineers.

2. Git:

Git and Github have been around for a long time, and while I’ve used Git with Eclipse in the past, I’ve yet to grasp Git on the command line.

Why haven’t I figured out Git yet? Simply because I didn’t require it at the time. I’ve downloaded projects from Github and ran them from Eclipse on occasion, but I’m still not very good with Git commands, especially when it comes to undoing changes and managing failures.

Because most firms are moving their projects from SVN and CVS to Git, now is the best time to learn and master Git. I recently acquired Git Complete: The comprehensive, step-by-step tutorial to Git from Udemy during their most recent $10 deal, and this will be the first item I finish in 2022.

If you’re in the same position as me and want to learn or enhance your Git skills in 2022, I recommend checking out the Udemy course.

3. Java 9–17:

As I previously stated, I am still learning Java 8, as are many other Programmer. In 2022, I’ll devote some time to studying new features of Java 9, Java 10, and Java 17, but until then, Java 8 will remain a top focus for me until I move on to Java 17, which is another LTS release.

Modules, Jigsaw, Reactive Streams, Process API, HTTP2 client, JShell, and API enhancements like collection factory methods are all included in JDK 9, and I’m looking forward to understanding them as soon as possible.

Similarly, JDK 10 introduces var to offer you a taste of dynamic type while also improving GC.

I acquired a number of courses during the recent Udemy $10 sale, one of which being The Complete Java MasterClass, which has been updated for Java 11, and I am excited to begin my Java 11 journey with it.

If you haven’t yet started with JDK 8, here’s a selection of my favourite Java 8 lessons and courses that you may access for free: The top ten tutorials for learning Java 8.

If you require a list of courses to study new features from Java 9 to Java 13 then you may take a look at the following of courses to learn new technologies from JDK 9 to JDK 13.

4. Spring Framework 6:

I’ve heard about several new features, such as Spring 6’s reactive programming style, adoption of newer Java capabilities, and improved unit testing, but I have yet to try them out.

Anyway, I’ve already begun learning Spring 5.0 by following Spring 5. 0: Beginner to Guru, and I want to keep up the pace in 2022. If you utilise Spring, now is definitely the greatest time to learn about version 5.0.

If you enjoy reading, Manning and Packt Pub have compiled a collection of expert Spring Books for Java developers.

5. Unit testing:

Another area that I’d like to develop in the coming year is my writing. Mockito and PowerMock for mocking objects, Robot Framework and Cucumber for automatic integration tests, and of course the current and dazzling JUnit 5 library are just a few of the new frameworks and tools currently offered for Java developers to unit test and integration test their applications.

This is an area where there is a lot to learn. If you devote some time to improving your unit testing skills, not only will your coding skills increase, but you will also evolve into a more professional developer, which is something that every employer seeks. To get started, have a look at Udemy’s JUnit and Mockito Crash Course.

6. RESTful Web Service:

RESTful Web Service is a kind of RESTful Web Service that allows you to

In 2022, I’d like to improve my expertise of building REST APIs and implementing safe and scalable RESTful Web Services in Java using Spring.

This is a highly sought-after ability in the Java industry, and few people are proficient in both Java and REST.

If you’re in the same position as me and want to learn how to create RESTful Web Services using Spring, Eugen Paraschiv’s REST of Spring MasterClass is a fantastic place to start.

7. Spring Security 5.0:

This is Spring Eco-third System’s significant update. The renowned security framework’s 5th edition includes various bug fixes as well as a big OAuth 2 module that you won’t want to miss.

Along with the Spring 5.0 framework, this is yet another project on my priority list for 2022.

Thankfully, Eugen has revised his top-selling Learn with Spring Security course to cover 5.0 features and a distinct lesson for OAuth 2.0, making it the greatest resource for learning Spring Security 5.0 right now.

8. Spring Boot 2:

The Spring Boot framework has been updated to version 2. If I have time after completing all of these goals this year, I plan to study Spring Boot 2.

If you’re interested in learning Spring Boot 2, you can get a head start with this free Udemy Spring Boot course.

9. React JS or Angular 2+

The way you design online apps has fundamentally altered thanks to these two JavaScript frameworks.

I’ve used Servlet, JSP, and jQuery on the client side as a Java developer, but I haven’t yet explored Angular or React.

One of my objectives for 2022 is to study Angular, and I’ll begin with Udemy’s Angular – The Complete Guide. If you’re in the similar boat, you should check into that course; it’s quite useful.

10. Android:

You are missing essential if you do not know how to create Android Apps in 2022. Mobile is one of the most effective platforms for reaching a huge number of people, and Android is the most famous platform for developing mobile apps.

Despite knowing the basics of Android, I have yet to launch any Android applications; perhaps 2022 will alter that. If you want to study Android in 2022, you should look at The Complete Android N Developer Course, which is one of the best Android courses available.
