synchronization - cannot wake a sleeping thread?

[Nigel Shrin]

'notify' will make runnable a waiting thread, but a sleeping thread will always sleep it's time?
There is no method to wake a sleeping thread?

thank you

Never mind. It's late. I'm going to bed now

Good plan! I think I should also - think with new head tomorrow!

Ah - might have found the answer:
you can use an interrupt(), but have to handle/declare an interrupt exception

Is that right?!

notify() and notifyAll() methods will notify the Threads, which are waiting for execution, in the pool. I think it's correct thet we can call interrupt() method to interrupt that sleeping thread. But don't have any example coding!

Waiting and sleeping are two different things. notify and notifyAll won't wake up a sleeping thread. Only the interrupt method can be used to wake a sleeping thread...

Yea! Thanks Ankit!
