Put a stopwatch in a JFrame

Question

Hi. Can anyone tell me the simplest way to put a stopwatch in a JFrame? I saw some examples but I couldn't quite understand them.

You didn't have to be so sarcastic! :) Anyway, I'm working on a quiz and I want to time how much it takes a person to finish the quiz. Here is my stopwatch class for the moment..
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.text.*;
import java.util.*;
public class Cronometru extends JLabel
     int delay=1000;
     int counter=0,hours=0,minutes=0;
     Date date=new Date();
     private final static SimpleDateFormat sdf=new SimpleDateFormat("hh:mm:ss");
     ActionListener action=new ActionListener(){
          public void actionPerformed(ActionEvent e)
                    counter++;
                    if (counter<60)
                         date.setSeconds(counter);
                    else
                         if(minutes<59)
                              date.setMinutes(++minutes);
                         else {date.setHours(++hours); minutes=0;
                         counter=0;
                    setText(sdf.format(date));
     private javax.swing.Timer timer=new javax.swing.Timer(delay,action);
     public Cronometru()
          timer.start();
}
