Can you explain how dynamic memory management works in the heap area in the context of programming languages?

In programming languages such as Java, dynamic memory management in the heap area is performed using a garbage collector (GC). The heap is a memory area where objects created during program execution are stored.

When a new object is created, memory is allocated in the heap. The programmer does not manually manage memory release — this is done by the GC, which periodically checks which objects are no longer reachable from the code (no references to them) and frees their memory.

Main stages of GC operation:

• Marking: identifying objects that are still in use.
• Cleaning: removing objects that are no longer used.
• Compaction: compressing memory to reduce fragmentation (in some algorithms).

This helps prevent errors related to memory leaks and double freeing, making development easier.
