here the GC calls an object's FINALIZE metod immediately 
befoer it collects an object that is no longer reffered by 
the application
GC doesnt actually run finalize metod  when the GC finds a 
FINALIZE method it queues the obj up for the finalizer to 
execute the objects metod

GC checks for those resources which are no longer used by 
the process. To release the memory from these resources and 
in order to regain the memory heap GC initiates destructors 
to destroy such instances of the program. Before the 
destructor void an instance variable finalize routine gets 
executed. This routine performs whatever is to be done 
before the object return to void state or prior to release 
of any unused resources.
