How deadlock is achieved in java?
A Deadlock is a situation of indefinite waiting where the system is stuck at a particular point and would do nothing useful. For example Method A is waiting for B's input while B is waiting for C's input and C in turn is waiting for A's input. Here all the 3 methods would continue to wait because they are waiting on one another and the system is stuck. A deadlock usually occurs while using threads. Threads can lock objects on which they are processing and when multiple threads are waiting for the same object a Dead lock may occur. The use of the synchronize keyword can be used to avoid such deadlock situations.
