What is the best way to exit a Runnable thread immediately?

[Ken Adams]

Basically I implement the Runnable interface and in my run function I do
have a while loop that checks a condition to quit, but what if my run
function is long say calls a bunch of different methods. Do I have to wait
till all the methods finish. I want to be able to quit anytime in the
progress of these functions. I suppose I could check the condition between
each method call but that doesn't seem like a very good choice. Any
suggestions?


Thanks

Checking multiple times is about what you want to do, if you need to
check several times per loop iteration.

My understanding is that checking a flag is the best, but if there are
latency problems you might see what happens if you use this:
public void interrupt() {}
which is in the Thread class. Then your thread must have a handler.
