Schedule a task and generate beep

Example that uses java.util.Timer to schedule a task to execute once 3 seconds have passed.

ScheduleAndBeep.java

import java.util.Timer;
import java.util.TimerTask;
import java.awt.Toolkit;

public class ScheduleAndBeep {
	Toolkit toolkit;
	Timer timer;

	public ReminderBeep(int seconds) {
		toolkit = Toolkit.getDefaultToolkit();
		timer = new Timer();
		timer.schedule(new RemindTask(), seconds * 1000);
	}

	class RemindTask extends TimerTask {
		public void run() {
			System.out.println("Time's up!");
			toolkit.beep();
			// timer.cancel(); //Not necessary because we call System.exit
			System.exit(0); // Stops the AWT thread (and everything else)
		}
	}

	public static void main(String args[]) {
		System.out.println("About to schedule task.");
		new ReminderBeep(3);
		System.out.println("Task scheduled.");
	}
}
