Java Garbage Collection Algorithms

Understanding Java GC principles and algorithms

Garbage collection is an essential but often misunderstood part of application behavior on Java platforms. It is therefore important for Java developers to understand how collection mechanisms and algorithms work.  

This comprehensive video presentation by Azul's CTO Gil Tene reviews and classifies the major garbage collectors available in JVMs today. Following an overview of typical garbage collection techniques such as incremental and concurrent, generational, parallel, and stop-the-world, algorithms, it defines terms and metrics which all collectors share. It also discusses trade-offs in balancing requirements for throughput, space, responsiveness, and available memory, and covers some common misconceptions, pitfalls, and garbage collection behavior myths.
