What we’re about
The primary focus of The Belgium Java User Group (founded in 1997 by Stephan Janssen) is to inform our members about the Java ecosystem.
We regularly organise free sessions for Java and JVM interested developers, devops and teamleads to socialize, learn and inspire.
Interested to contribute and participate in our vibrant and independent Java community here in Belgium? Reach out to the team! We are always looking for new speakers and Meetup Hosts.

Topics
Badr's Topic: Exploring Project Loom in Java: The Future of Concurrency
This Quickie session will focus on the technical advancements of Virtual Threads, providing engineers and developers with insights into how Java is evolving to support high-performance, scalable applications with simpler concurrency models.About Badr
Badr Kacimi (LinkedIn) is a Senior Software Engineer at Blue Harvest Belgium. He has contributed to impactful projects across finance, travel, and other industries. He specializes in Java and AI-driven solutions, is passionate about tech innovation, and writes insightful articles. In his downtime, he enjoys football and e-sports.Simon's Topic: The Art of Java Language Pattern Matching
The goal of project Amber within OpenJDK is to explore the inclusion of smaller, productivity-oriented Java language features. Pattern matching is one part of this that has delivered new functionality in recent versions.Pattern matching combines application code logic to test if an expression has a specific type or structure and extract components of its state for processing.
Pattern matching is now well embedded in the Java language using the following features, defined by JDK Enhancement Proposals (JEPs):
· Pattern matching for instanceof (JEP 433)
· Pattern matching for switch (JEP 441)
· Record patterns (JEP 440)
· Unnamed patterns and variables (JEP 456)
· Primitive types in patterns, instanceof and switch (JEP 455)In this session, we’ll look at the details of these new language features and a more general look at pattern matching.
We’ll also have some fun with several Pattern Puzzlers that show how you need to be careful with some edge cases.
The session will hopefully both be informative and fun!
