Apr 8, 2025 · Java garbage collection is an automatic process that manages memory in the heap. It identifies which objects are still in use (referenced) and which are not in use (unreferenced). It removes the objects that are unreachable (no longer referenced).

Jan 10, 2025 · Java manages memory through the Java Virtual Machine using a process called garbage collection. Garbage collection automatically frees up memory by removing objects from the Java heap that are no longer needed. Garbage collectors use the Mark and Sweep algorithm to clear unused memory.

Nov 4, 2015 · Understand the Java Memory Model for the heap, as well as garbage collection algorithms, and memory leak best practices all with diagrams and bite-sized descriptions.

May 10, 2022 · Any garbage collection algorithm must perform 2 basic operations. One, it should be able to detect all the unreachable objects and secondly, it must reclaim the heap space used by the garbage objects and make the space available again to the program.
