Java: Wait for TimerTask to complete before continuing execution

Question

I\'m having a bit of an annoying problem. Right now, I have a snippet of code that starts a thread, sets a timer within that thread, and then exits that thread and continues wit

Answer 1

I believe a CountDownLatch will do what you want.

final CountDownLatch latch = new CountDownLatch(10);
int delay = 1000;
int period = 1000;

timerPanel.setText(Long.toString(latch.getCount()));

timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
    public void run() {
        latch.countDown();
        timerPanel.setText(Long.toString(latch.getCount()));
    }
}, delay, period);

try {
    latch.await();
}
catch (InterruptedException e) {
    e.printStackTrace();
}

timer.cancel();
