Hi Sandeep,

In ABAP, there is a system routine, that automatically deletes objects ( instances) that can no longer be addressed from the memory which is called a garbage collector. It releases the memory space they occupied.

For Eg.

Data: VAR1 TYPE REF TO CLASS1,

VAR2 TYPE REF TO CLASS1.

Now VAR1 & VAR2 are reference varibales.This acts a s a pointer to the objecct.

CREATE OBJECT VAR1.

Now VAR1 will have a momory space allocated in the system

.

CREATE OBJECT VAR2.

Now VAR2 will have a momory space allocated in the system .

Now if we do ,

VAR1 = VAR2.

Now both of the Variables are pointing to the same object . So one object will becone free.

This will get deleted by the garbage collector.
