Read MoreAll Features in Java 26 - Inside Java Newscast #102
Java 26, or rather JDK 26, enters rampdown phase 1 today, which sets its feature set in stone. With added HTTP/3 support, performance and AOT improvements, new command-line flags to manage final field mutation, and a steady progression of previews, it moves Java forward.

Read MoreAgent Orchestration with LangChain4J
Langchain4j is a library that enables developers to easily integrate language models and AI workflows into Java applications, gaining traction within the Java and enterprise AI communities. With the langchain4j-agentic module, you can combine AI (and non-AI) agents into powerful but controlled workflows. In this session, Lize explores the core patterns: sequential, looping, conditional, and parallel, plus the supervisor pattern where agents decide for themselves which tasks to run. She also covers human validation strategies that keep your agents in check. Compound agents wrap entire workflows into a single building block, while AgenticScope provides control over context and a clear view of the call chain. Through playful demos, this presentation shows agent systems that scale from small tasks to complex automation. Whether you are just curious about AI or ready to experiment in your own codebase, you grasp what is possible today, how to keep it under control, and how Java developers shape the next rise of the agents.
Read MoreGarbage Collection in Java: Choosing the Correct Collector
Garbage collection (GC) is a type of automatic memory management and a key feature of the Java platform. It allows developers to focus on their application logic rather than low-level memory management issues. The Java platform implements multiple garbage collection algorithms, making it suitable for handling all kinds of workloads. The default collector, G1, is often a great choice, but depending on your use case, another GC might provide even better performance. This video explores: the basics of garbage collection, why there are multiple collectors, key characteristics of G1 and ZGC and the performance differences between collectors and JDK releases.
