Java Community in 2025: Where to Find Knowledge and Like-Minded People

Java Community: Your Compass in the World of Enterprise Development

Java is not just a programming language. It is an entire ecosystem that lives, breathes, and evolves thanks to its community. If you write in Java, you are part of a huge family that includes millions of developers worldwide. But how do you not get lost in this ocean of information? Where to gain knowledge, with whom to discuss architecture, and where to go for inspiration?

In this article, we will break down the main entry points into the Java community: from iconic conferences to cozy blogs. You will learn where the best Java developers publish, which resources you should subscribe to right now, and how to write code you won't be ashamed to show your colleagues. Let's go!

Java Conferences: A Place of Power for Developers

No online course can replace live communication. Conferences are not just talks, but also networking, hallway memes, and the opportunity to ask a question to the author of your favorite framework. Here are three landmark events that every Java developer should attend.

Devoxx (Belgium and other countries)

The main European Java conference. The creators of Java, key Spring committers, and authors of the most popular libraries speak here. Tickets sell out in hours, and the program is so packed that you have to choose between 5 parallel tracks. Tip: get a Pro ticket — you'll get access to workshops where you can write code under the guidance of masters.

Joker (Saint Petersburg / Moscow)

The largest Russian-language conference on JVM languages. If you want to hear world-class talks in Russian, this is the place for you. Joker is famous for deep technical talks about Garbage Collection, performance tuning, and the internals of HotSpot VM. After the conference, be sure to check out the after-party — that's where the best open-source projects are born.

JavaOne (online + offline)

The official Oracle conference. It used to be a grand event in San Francisco, but has now transformed into a hybrid format. New versions of Java are announced here, and demos of Project Loom and Valhalla are shown. Plus, it's the best place for career advice: FAANG recruiters are right in the lobby.

Blogs That Change Your Code

Conferences are once a year. But blogs are daily practice. Subscribe to these resources, and your code will become cleaner, and your architecture more robust.

Baeldung — Your Desktop Reference

If you google "how to do X in Spring Boot" — you're already on Baeldung. It's a giant database of tutorials with code examples. A special feature: each example can be run directly in the browser via a built-in compiler. Author Eugeniu Paraschiv updates the content weekly, covering even the newest features of Java 21.

// Example from Baeldung: Working with Virtual Threads (Java 21+)\npublic class VirtualThreadExample {\n    public static void main(String[] args) throws InterruptedException {\n        Thread virtualThread = Thread.startVirtualThread(() -> {\n            System.out.println("Hello from a virtual thread!");\n        });\n        virtualThread.join(); // Wait for completion\n    }\n}

InfoQ Java Edition — Analytics for Architects

Not just news, but deep analysis of trends. Articles are written by leading engineers from Google, Netflix, and Alibaba. Here you will learn how Netflix rewrote its stack on Java 17, or how Alibaba optimizes GC for 10K TPS. Useful for those designing high-load systems.

Habr — Russian-Language Must-Read

The "Java" section on Habr is a living organism. Both beginners and authors with 15 years of experience publish here. The main advantage is the comments. Under any article, a discussion flares up where experienced developers explain the nuances. Tip: look for articles with the "Java Performance" tag — there are real gems there.

Resources for Leveling Up: From Beginner to Senior

The Java community is rich not only in conferences and blogs but also in tools that make development
