CountDownLatch控制线程是否超时

public static void main(String[] args) throws InterruptedException {
        CountDownLatch latch = new CountDownLatch(1);
        long start = System.currentTimeMillis();
        System.out.println("I'am start--->" + start);
        Thread t = new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    System.out.println("I'am dead");
                    Thread.sleep(50000000);
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {

                }
                latch.countDown();
            }
        });
        t.start();

        latch.await(10, TimeUnit.SECONDS);  //等待10秒后，如果线程没有执行完，则不再等待，进入后续
        System.out.println("Game Over");
        t.interrupt();
       // t.stop();
        long end = System.currentTimeMillis();
        System.out.println("I'am end--->" + end);
        System.out.println(end - start);
    }
