How do I schedule a task to run at periodic intervals?

[phpuser123]

was trying some codes to implement a scheduled task and came up with these codes .

import java.util.*;
 
class Task extends TimerTask {
 
int count = 1;
 
// run is a abstract method that defines task performed at scheduled time.
public void run() {
    System.out.println(count+" : Mahendra Singh");
    count++;
}
 
}
 
class TaskScheduling {
 
public static void main(String[] args) { Timer timer = new Timer();
 
   // Schedule to run after every 3 second(3000 millisecond)
   timer.schedule( new Task(), 3000);   
 
} }
 

My output :

1 : Mahendra Singh

I expected the compiler to print a series of Mahendra Singh at periodic interval of 3 s but despite waiting for around 15 minutes, I get only one output...How do I solve this out?

Please see this link for timer class information.
I don't see a listener here.
