The location of an individual object in JVM Heap Space

I am able to monitor the java application with various tools at JVM level. I can dump heap objects and find out the number of the objects and their total size.

At this point, I would like to know the heap location of each object, I mean, as you may know that there are three heap sections (eden, old, perm spaces), at the time of dump which object located at which heap space.

The location of an individual object is not something you can trace. Just dumping the heaps can result in the objects moving. Whatever you are trying to do I suggest you do another way.

BTW: If you do a dump of "live" objects this triggers a full GC which can move all objects into the old gen, so in that situation you know where all the objects are. ;)
