Java’s garbage collection process automatically manages memory for objects in the heap. Here’s a simplified breakdown:
Identifying Unused Objects: The garbage collector scans the heap to find unreachable objects. These are objects with no references pointing to them from your program.
Marking Reachable Objects: It starts by identifying “root” objects (global variables, local variables holding references). Then, it traces all objects reachable from these roots. Reachable objects are considered in use.
Cleaning Up: Unreachable objects are deemed garbage and removed from memory, freeing up space in the heap.
This is a basic overview. There are different generations in the heap with varying collection frequencies, and some garbage collection cycles may involve compacting the heap to improve memory allocation efficiency.
