What are the different garbage collection algorithms in Java?

What are the different garbage collection algorithms in Java?

Java has several garbage collection algorithms, including Serial, Parallel, CMS (Concurrent Mark-Sweep), and G1 (Garbage-First). Each has its own use cases and performance characteristics.

Can you explain how the G1 garbage collector works?

The G1 garbage collector divides the heap into regions and prioritizes the collection of regions with the most garbage. It aims to achieve predictable pause times.

What are the advantages of using the CMS collector?

The CMS collector is designed for applications that require low pause times. It performs most of its work concurrently with the application threads, minimizing interruptions.

How do I choose the right garbage collector for my application?

Choosing the right garbage collector depends on your application's performance requirements, memory usage patterns, and acceptable pause times. Testing different collectors in your environment is recommended.
