Threaded Timer Class

I need to create a threaded timer class.

This class will start at each junit test and end when the test complete, but if the test does not complete in a certain time interval, it should fail the test.

Still very green to Java, so any help would be appreciated.

Something like this might work

Code:

---

public class Test
{
        private volatile Thread th;

        public Test(final int timeout)
        {
                th = new Thread(new Runnable()
                {
                        @Override
                        public void run()
                        {
                                try
                                {
                                        Thread.sleep(timeout);
                                        assert false;
                                }
                                catch (final InterruptedException e)
                                {
                                        e.printStackTrace();
                                        assert false;
                                }
                        }
                });
                th.start();
        }

        public void complete()
        {
                th = null;
        }
}

Thanks!
I did not use it (found the @Test annotation in jUnit have a timeout property, so been using that).
But do have to get to threading sooner or later (as I've switched to Java), so this will be helpful.
