What garbage collection mechanism is used in your development environment or project?

Java uses a garbage collector (GC) that automatically manages memory by freeing unused objects. Modern JVM versions employ several garbage collection mechanisms, such as:

• G1 (Garbage First) GC — focused on minimizing pauses and efficiently managing large heaps.
• Parallel GC — uses multiple threads to speed up collection.
• CMS (Concurrent Mark Sweep) — an older implementation that performs collection concurrently with the application.

The choice of mechanism depends on JVM settings and application requirements. For example, server applications often use G1 GC, which balances performance and pause times.

Thus, garbage collection in Java is an automatic process that frees memory by managing the lifecycle of objects without manual intervention.
