Say I've got something like this

public void run(){
    Thread behaviourThread = new Thread(abstractBehaviours[i]);
    behaviourThread.start();
}

And I want to wait until abstractBehaviours[i] run method has either finished or run for 5000 milliseconds. How do I do that? behaviourThread.join(5000) doesn't seem to do that afaik (something is wrong with my code and I've put it down to that).

All the abstract abstractBehaviour class is of course Runnable. I don't want to implement it inside each run method as that seems ugly and there are many different behaviours, I'd much rather have it in the calling/executing thread and do it just once.

Solutions? First time doing something as threaded as this. Thanks!
