As a programmer, your biggest challenge is to keep yourself up-to-date. Technology always changes very fast. Then you will see a new version of your favorite programming language and framework coming to every year. Here are Top 5 Skills Java Developer Should Learn in 2021
For Java developers, the last, 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.
You have to managed to catch up many of those last years, hence, 2021 will be all about consolidation and keeping myself up-to-date with things which matter most on the technology side.
What Java Programmers should learn in 2021
1. DevOps
People these days perceive software as a swift changing aspect due to which it is crucial to learn DevOps in 2021. In the current scenario, one should be familiar with DevOps for a kick start to their career, especially if they are from an IT background.
However, no matter whether you are a system admin, security specialist, or a developer, learning DevOps will shape an enhanced path for you. If you have perused DevOps and have your hands on it, you can make your work more relevant and qualitative.
You can also propose solutions with useful knowledge to your clients for a healthier approach. The more you sharpen your skills with DevOps, the more chances of global presence increases.
2. Git
A web developer needs to be smart and agile in their work. When something goes wrong in the development process, one cannot afford to start over with a project from scratch again.
That’s why it is essential to learn Version Control like Git and Github. This allows you to keep a consistent track of your development process so you can rollback to a previous version when something goes wrong. A full-stack web developer working on tight deadlines absolutely needs this skill.
3. Java 9-15
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.
4. Spring Framework 5
As you can see, Spring is the most widely and popularly used framework. Now if you are looking for why its so, wait for it. Let me start by explaining a little about Spring.
Spring Framework is a powerful lightweight application development framework used for Enterprise Java (JEE).
The core features of the Spring Framework can be used in developing any Java application. It can be described as complete and modular framework.
The Spring Framework can be used for all layer implementations of a real time application. It can also be used for the development of particular layer of a real time application unlike Struts and Hibernate, but with Spring we can develop all layers.
5. Angular
These two JavaScript framework has completely changed how you develop web applications. In 2021, you have to learn Angular. Why? Simple, because Angular is easier.
The new Angular codebase is more modern, more capable and easier for new programmers to learn than AngularJS, while also being easier for project veterans to work with.
With AngularJS, programmers had to understand the differences between Controllers, Services, Factories, Providers and other concepts that could be confusing, especially for new programmers.
Conclusion
Technology changes with rapid speed, and the biggest challenge for programmers are to keep themselves up-to-date. So, you have to follow where technology lead the world.
