killing threads

I want to start a thread, that does some work for me. If the thread doesn't finish within 5 seconds, i want to abort it. For a thread, that extends "Thread" this is no problem:

myThread.join(5000);

But how can I do that, when my thread doesn't extend "Thread" but implements "Runnable" ? Runnable doesn't support "join".

How can I generally kill running threads ?

thanx

Even if your class implements Runnable then you still have to create a thread object for your thread.
So you can always use join.

public class Test implements Runnable {

    public static void main (String args[]) {
        Thread t = new Thread(new Test());
        try { t.join(1000); } catch (Exception e) {}
    }

    public Test() {
    }

    public void run() {
        // do something
    }
   
}

your right - it works :) i tried this before, but i didn't work then - maybe i mistyped something...

ok objects - I still haven't posted my recomendations in the cleanup area so I can change this, BUT: this is why I am not sure whether to recomend your comment as an answer:

the question is: "How can I generally kill running threads ?"

I couldn't find a clear answer to it. Yes - your comment is correct, but also - you didn't pretend for the points when Moondancer
posted his comment.
Do you still think that the points should go to you?

That was part of the question, and the only way I think it can really be done is to exit the application.
Ben seemed happy with the answer I gave :)
