How can I execute code when exiting a thread

Question

I want to execute code at the very end before a thread dies. So what I am looking for is some kind of dispose(), tearDown() method for threads guaranteeing that certain tasks are performed before exiting the thread.

You can wrap the code to be executed in a separate thread in your own code that has a try/ finally block, and call the run method of the "real" Runnable from the try, like this:

final Runnable realRunnable = ... // This is the actual logic of your thread
(new Thread(new Runnable() {
    public void run() {
        try {
            realRunnable.run();
        } finally {
            runCleanupCode();
        }
    }
})).start();

The code of runCleanupCode() will be executed in the same thread that was used to run the logic of your actual thread.
