5 Superb GitHub Repos That Every Java Developer Must Know About

Getting your Trinity Audio player ready...

Since the last decade, there has been enormous growth with a number of programming languages being created and used in developing projects. However, every language has its own set of advantages and disadvantages. For developing enterprise applications, Java is still the most preferred programming language among developers and programmers.

Java has some powerful weapons in its arsenal, including high performance, strong memory management, and high security. It also has one of the most mature developer communities in the world. In fact, as of today, Java is the second most popular tag only after JavaScript on StackOverflow.

The tags on StackOverflow demonstrate a topic’s popularity, Java is the 2nd popular tag

Personally, I have been programming in Java for over 6 years now and from what I have learned, bigger organizations prefer performance and security in their web applications, which Java is recognised for. It is used to create software for a variety of platforms. It is a statically typed programming language, which allows it to run quicker than other languages such as Python or JavaScript. The language is simple and straightforward to write. The best thing about Java is that it is machine-independent.

With that in mind, I’ve created a list of GitHub repositories that I found quite useful and that would be of great benefit to any developer, whether seasoned or a newbie, in his quest to learn the language.
