thread started a process, now what?

I have a class that starts up a thread and inside thread's run() method is called. Rougly it goes like this:

So here thread starts a timer and runs until either longTask() returns something or timer expires.

I have two questions:

1.Is while loop in run() enough to kill a thread?
2.longTask() is an abstract method that must be implemented by extending class, so if there is a long process in the implementation of longTask(), when this thread dies will/should whatever is going on in longTask() die as well?

Here's how I approached the same requirement ... if I got it right

I don't have my actual code in hand, but I think join(nnn) just returns after the time and doesn't throw anything. I did this because I couldn't find any way to kill the long running task or make it time out. If it takes more time than allowed, I exception out but the task goes on to completion and the result is thrown away.

Does that solve the right problem?

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
It is sorta covered in the JavaRanch Style Guide.
