java - stack and heap

     Stack and Heap are the memory location in the JVM where variable and object can be stored.

Instance variable------------
                                           |-----------> can be stored in the heap memory
Objects---------------------


Local variable ----------------------> can be stored in the stack memory

for example :

class A{
int a;         ------------------>Instance variable
string b;
                                 |--------------------->local variable
void getName(String name)
{
this.name;
}
public static void main(String arg[])
{
A a = new A();----------------------object
A.getName("siva");
}
}


Here in this program,

A a;----------->This can be stored in stack memory.

new A();------->This can be stored in heap memory.
