Attention:

Heap Memory Composition Total heap memory = Young with heap memory + aged with heap memory + persistent heap memory

Young with a heap of memory when the object was just created, put it here.

Old age with a heap of memory objects will be placed here before they are actually recycled.

Persistent heap memory class file, metadata, etc. put here
