I don't understand how catch block will be execute here ? i can't see any reason that will throw InterruptedException.

[admin]

Right. It is not throwing InterruptedException. The assignment is after the catch block.

Thank you

what would be the answer if the assignment where in the catch block?

[admin]

If the assignment were in the catch block, you would have to interrupt the hello thread while it is sleeping. You can do that by calling t.interrupt(); in main.
However, main may still fail to print 20 because the main thread could keep running and print 0 before the code for assignment gets to run.
So you could add t.sleep(2000); after t.interrupt() to see that assignment is done and then the value is printed.

You should try out various options to see how it works.

HTH,
Paul.
