This session will be about memory allocation, object lifecycle, and garbage collection strategies within the Java Virtual Machine (JVM). Attendees will gain insights into memory allocation strategies, object retention policies, and various garbage collection algorithms like generational and concurrent collection. So when you are interested in getting more knowledge about which garbage collector to use best for your application or about memory management in the JVM, this session is for you. ## Speaker ### [Gerrit Grunwald](https://www.wearedevelopers.com/@gerrit-grunwald) Senior Developer Advocate at Azul Systems ## Related talks at this congress - [High performance Serverless Java on AWS](https://www.wearedevelopers.com/events/world-congress-2025/sessions/623-high-performance) — Vadym Kazulkin - [Modern Java 25](https://www.wearedevelopers.com/events/world-congress-2025/sessions/562-modern-java-25) — Ron Veen - [CRaCing Java Snapshots](https://www.wearedevelopers.com/events/world-congress-2025/sessions/867-cracing-java) — Pasha Finkelshteyn - [Developer Joy with Quarkus](https://www.wearedevelopers.com/events/world-congress-2025/sessions/498-developer-joy-with) — Daniel Oh
