Thanks

Garbage collection run in background by the JVM. The job is to clear the memory allocated for the objects using the new. The clear process succeeds in clearing the memory allocated  for a particluar object when it's refernce count becomes zero.

MyObj ob1 = new MyObj();
MyObj o2 = ob1;

Now reference count for MyObj is 2. When it becomes zero, MyObj will be deleted by Ref counter.
