Recurring Countdown Timer in Java

Question

I\'m trying to implement a countdown timer into a pre-existing public class and I have a few questions.

An overview: I want to have a timer within a program that counts

Answer 1

You could use java.util.Timer to schedule an execution of a method and then cancel it if the requirements is met.

Like this:

timer = new Timer();
timer.schedule(new Task(), 60 * 1000);

And then make a class like this to handle the timerschedule:

class Task extends TimerTask {
    public void run() {
      System.exit(0);
    }
  }

If the requirements is met, then do this to stop it from executing:

timer.cancel();
