How to stop the java timer

Question

I tried writing a program for a scheduler using java , compiled and ran in java 1.6 .The code is given below
import java.util.*;
public class TimerTaskEx2 {
     public static void main(String[] args) {
          Timer timer = new Timer();
          timer.scheduleAtFixedRate(new TimerTask(){
               public void run() {
                    System.out.println("Java");
          }, 5000, 1000);
output
Java
Java
Java
Java
Java
Java
Java
The output of this program starts after 5 milliseconds delay and keeps running infinitely becoz the program is written only in such a way .
but my actual requirement is the timer should start 5 milliseconds after i run the program and stop after 20 milliseconds .
Here I need to know how to stop it at a required time interval
I dont find any api regarding this in 1.6 spec .
please clarify how to do that .
Thanks

try this code:
import java.util.*;
public class TimerTaskEx2 {
     public static void main(String[] args) {
          Timer timer = new Timer();
          timer.scheduleAtFixedRate(new TimerTask() {
               int i = 0;               
               public void run() {
                    System.out.println("Java");
                    i++;
                    if (i > 3)
                         this.cancel();                    
          }, 5000, 1000);
