JDK Timer scheduler example

JDK Timer is a simple scheduler for a specified task for repeated fixed-delay execution. To use this, you have to extends the TimerTask abstract class, override the run() method with your scheduler function.

RunMeTask.java

package com.mkyong.common;
 
import java.util.TimerTask;
 
public class RunMeTask extends TimerTask
{
 @Override
 public void run() {
  System.out.println("Run Me ~");
 }
}

Now, you can schedule it by calling the schedule() method of Timer.

public void schedule(TimerTask task,
                     long delay,
                     long period)

App.java

package com.mkyong.common;
 
import java.util.Timer;
import java.util.TimerTask;
 
public class App 
{
    public static void main( String[] args )
    {
 
     TimerTask task = new RunMeTask();
 
     Timer timer = new Timer();
     timer.schedule(task, 1000,60000);
 
    }
}

In this example, the timer will print the “Run Me ~” message every 60 seconds, with a 1 second delay for the first time of execution.
