Threads and Exceptions

[Surendra Kumar]

Hi,

I am confused with thread exceptions.
can someone please explain the difference in the exceptions InterruptedException, IllegalMonitorStateException, IllegalThreadStateException.

which exception th wait() method should be wrapped in?

[Ramamoorthy Periasamy]

InterruptedException

[Vepa Sritej]

InterruptedException is thrown when any thread is interrupted while it has executed sleep() or wait().
IllegalMonitorState Exception is thrown when any thread executes wait() without holding a lock on an object.

InterruptedException must be handled via try..catch or must be declared in the method defintion. IllegalMonitorState is thrown by JVM..

[Surendra Kumar]

what about IllegalThreadStateException?

[Praveen Babu]

When the start() method is called twice on single thread then it throws IllegalThreadStateException.
