Where instance variables(primitives) are stored in java? Is anyhow stack related to instance variables storage?

Question

Where instance variables(primitives) are stored in java?

Answer 1

Primitive variables are stored in the same places all variables are stored (including references):

• Within objects created (allocated) on the heap, or
• Within method stack frames as local variables, or
• Within static areas of their containing class (which are on the heap).

Answer 2

If you mean instance fields declared on a class, they are allocated on the heap as part of the object's own allocation.

Primitive (value type) variables declared as method locals are stored in the method's stack frame.
