Hey class1 obj; 'obj' is of course a variable of type class1 which (assuming it's a local variable) is currently undefined. However storage for it (4 bytes on a 32-bit system or 8 bytes on a 64-bit system) has already been reserved for it within the method's stack frame. class1 obj=new class1(); 'obj' is again a local variable of type class1 which has a slot on the method's stack. However an instance (or object) of class1 has been created on the heap and a reference (or pointer) to it has been assigned to the variable. Consequently the variable's slot contains a reference to that instance - it doesn't contain the instance itself.
