why instance variable on heap?

[Arun Maalik]

Dear sir would you please explain me that why

---->Instance variable and object live on heap?
----->Local variable and method live on stack?

As we know that heap created on run time wheras stack form on compile time and i think that instance variable and object form on run time where as local variable and method form on compile time. I think due to this but i am not sure so please specify me.


Thanks
