Eden space is within the young generation space. Also there is old generation space. Then there is stack memory, survivor space 1 and 2. Then there is PermGen space and Pure Native area.

I was asked to write a java program preferable a web code to demonstrate when the object is stored in each of these JVM memory and when would it be destroyed and how the object moves about in these spaces.

Can someone please showcase here or share any existing material on the same?
