Need an idea in threads

Question

Dear all, hello.
Would someone tell me how the following is done?
MyThread is a class that extends Thread.
MyThread t1 = new MyThread().start();
MyThread t2 = new MyThread().start();
// Wait until EITHER t1 or t2 returns.
//Execute the rest of the program.
How that waiting part can be done?
Using
t1.join();
t2.join();
will wait for both threads to return.
But I need to proceed as soon as one of them completes its run() method.
Thank you.

.. but you need to make sure the lock is the same you use for wait(), so maybe something more like
public static final Object LOCK = new Object();
t1.start();
t2.start();
synchronized(LOCK) {
LOCK.wait();
run() {
synchronized(LOCK) {   
LOCK.notify(); //or notifyAll
