Can't you use interrupt() method?
Having stopWork() is great but what if this is not ur thread(does not have the method) or the thread is in sleep/wait mode, or waiting for IO (for example Socket s =server.accept())

both good suggestions, it seems to me!

stefan offers a nice, healthy-looking thread template, and yaroslav offers good advice about making provisions for (un)intended exit/shutdown

(i.e. "try" the 'do something' loop, "catch" InterruptedException, and possibly execute a "finally" block for clean shut-down)

I agree. Here's the link:
