A Java object's finalizer is invoked asynchronously some time after it has been accessed for the last time and before it is deallocated. Source: Internet
As a typical example, a Visual Basic program using a COM object is agnostic towards whether that object was allocated (and must later be deallocated) by a C++ allocator or another Visual Basic component. Source: Internet
Delphi is mostly not a garbage collected language, in that user-defined types must still be manually allocated and deallocated. Source: Internet
In contrast, in Java an object will not be deallocated by the garbage collector until it becomes unreachable (by the user program). Source: Internet
If the program attempts to access or deallocate memory that has already been deallocated, the result is undefined and difficult to predict, and the program is likely to become unstable and/or crash. Source: Internet
On the other hand, depopulation may cause a post office to close and its associated ZIP Code to be deallocated. Source: Internet
