A deadlock is when you have two or more processes that are each waiting for the other to finish. When this happens, neither one can continue and the program essentially stalls.

There is a basic example here

http://docs.oracle.com/javase/tutorial/essential/concurrency/deadlock.html

well documented.

but, a deadlock occurs when you wait for a object to be freed but that condition is never achieved.
