Task scheduling In Java

This is out of threading concept, threading is not used here. When you will run this example after a delay of 5 seconds a message will be printed in every 1 second:

Create a java file TaskScheduling.java in dev21century.threading package:

package dev21century.threading;

import java.awt.Frame;

import java.util.Timer;

import java.util.TimerTask;

class Task extends TimerTask

{

     int count = 1;

     /*run() is an abstract method

      which defines the task to be executed in scheduled

      interval */

     public void run() {

           System.out.println("Message from timer..");

     }

}

public class TaskScheduling {

     public static void main(String[] args) {

           Timer timer = new Timer();

           int delay = 5000; // 5 seconds

           int period = 1000; //repeate every seconds

           timer.scheduleAtFixedRate(new Task(), delay, period);

          

     }

}

Output:
