Object creation

[Anane]

When we use NEW word to create object of a class, it always creates object on HEAP memory. How can one create object on stack? If one creates object inside a function, then also object will be created in HEAP. Only object reference will be in stack. When function ends, object reference is destroyed, eventually object will be destroyed by GC. Am I correct with this concept?

In Java all objects are dynamic, i.e. you always have to 'new' them and they
are always created on a heap (not a C/C++ like heap); you can't create them
on the execution stack. And yep, you are correct.

There was a really good talk last year about eden space and such at JavaOne. It answered some questions about this topic I've always had. Lemme see if I can drudge up the link..
