This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
1) finalize will always run before an object is garbage collected
2) finalize may run before or after an object is garbage collected
3) finalize will run when an object becomes unreachable
4) finalize allows a programmer to free memory allocated to an object
Finalize will always be run before an object is garbage collected. It cannot run after it is collected because by then the object will cease to exit. When an object becomes unreachable it will be eligible for garbage collection but there is no guarantee when finalize will run, only that it will run before garbage collection happens. The final option is a passable description of destructors in C++ but not of the finalize method in Java.
I have not understood clearly explanation in terms of relation between garbage collection and finalize method. Any ideas, resources, links, sample code highly appreciated. thanks in advance.
