16 Top Java Communities, Forums and Groups: The Ultimate Guide

Developers didn’t need the transformation to WFH to understand the value of online communities and forums for their professional development and work. Many developer groups and forums offer supporting professional communities that assist with questions, dilemmas and advice. In fact, there are so many developer groups, it might be hard to choose. We’ve prepared a guide, which maps out the most active and helpful Java groups, Java forums and Java communities.

Java is a strong, popular and reliable programming language, used widely around the world. Among 9,000,000 Java developers, to be exact. Java supports multiple platforms, new architectures as well as older legacy systems, and enables developing many strong features. Whether you’re a Java newbie or a seasoned professional with 20 years of experience, you can benefit from Java user groups and forums.

We created a whitepaper with the top 16 Java forums, communities, and groups. Most of them cover a wide array of topics: from programming questions to discussions to job opportunities. Engaging in them can help your professional advancement, both by asking questions and by giving advice. They are also a place for networking and building your own personal brand.

Before posting in each, please make sure you check the appropriate type of content and questions on each community. Follow each community’s guidelines when joining them.

Here are the first three communities. You can get the full list by getting the whitepaper, here.

1. Java Tagged Questions on Stack Overflow

Stack Overflow is still the undisputed leader in developer forums and help. For anything Java related search for the questions tagged as Java, or just go here. You can ask and answer anything that has to do with learning and understanding Java itself. This is the place for inserting snippets of code and asking deep-tech questions.

We highly recommend searching for answers before posting and really making an effort to solve your problem on your own, otherwise community members will not hesitate to downvote you. Don’t get discouraged and don’t take offense if they do, try to read the feedback and interact with the other developers. When wielded correctly Stack Overflow can be a very powerful tool in your arsenal.
