ReminderTimerTask.java

import java.util.TimerTask;

public class ReminderTimerTask extends TimerTask
{
    public void run()
    {
        System.out.println("Wake up...");
    }
}

TimerDemo.java

import java.util.Timer;
import java.util.TimerTask;

public class TimerDemo
{
    public static void main(String[] args) throws InterruptedException
    {

        /*
         *
         * Creates a new timer whose associated thread may be
         * specified to run as a daemon.
         *
         * A daemon thread is called for if the timer will be used to
         * schedule repeating "maintenance activities", which must be
         * performed as long as the application is running, but should
         * not prolong the lifetime of the application.
         *
         * Parameters:
         *
         * isDaemon - true if the associated thread should run as a
         * daemon.
         */

        Timer timer = new Timer(false);

        TimerTask reminderTimerTask = new ReminderTimerTask();

        timer.schedule(reminderTimerTask, 5000, 2000);
        System.out.println("Timer has schedule the reminderTimerTask...");

    }

}

Output:

Timer has schedule the reminderTimerTask...
Wake up...
Wake up...
Wake up...
Wake up...
Wake up...
Wake up...
Wake up...
