How to kill a thread with another thread

[madhuri vl]

Hi,
I have a problem here like
If there are 2 threads t1 and t2 both running in a program and my task is t2 should kill t1 and stop running. Can anyone explain this?
Thanks in advance.
Madhuri.

Since the stop method is deprecated, I guess that the best thing you can do is send an interrupt to the thread t2 from t1. t2's run can work while !interrupted.

Like
t1.interrupt(t2);

Yeah, that's right.

Hi,
Thank You sunetra.

The interrupt() call is not guaranteed to work. If only t1 is on a wait() call, t2 can call interrupt() to do what you want to do.
I think there is a better alternative to achieve this. Use a common resource that both threads check. t2 can set the proper condition on which t1 can return and t2 can also check the same value and return.

Well, that common resource that one thread can set and the other one check -- that's the interrupted flag. No use reinventing the wheel. Cf Thread.interrupted().
