the follow code puzzles me, when i add "Toolkit.getDefaultToolkit().beep();" to it, it runs correctly. but when i remove this line ( //Toolkit.getDefaultToolkit().beep();" ), nothing will echo on the command.com,, could anyone tell me why ?

the code :

import java.awt.event.*;
import javax.swing.*;
import java.awt.*;


public class Temp {
public static void main(String[] args) {
int delay = 1000;
ActionListener taskPerformer = new ActionListener() {
int i = 0;
public void actionPerformed(ActionEvent evt) {
i++;
System.out.println("Hello " + i);
}
};
Timer timer = new Timer(delay, taskPerformer);
timer.start();
//Toolkit.getDefaultToolkit().beep();
}
}
