when making an applet...

what goes in the init(), start(), stop(), and destroy() methods?

what is the difference between and ?

lets say I have this simple code:

import javax.swing.*;
   import java.awt.*;
   import java.awt.event.*;
    public class Sample extends JPanel
   {
   	
   	//DRIVER
       public static void main(String[] args)
      {
         JFrame window = new JFrame();
         window.setTitle("Sample");
         window.setSize(300,100);
         window.setLocation(1,1);
         window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         window.setContentPane(new Sample());
         window.show();
      }
      private JButton button;
      private JLabel label;
   	
       public Sample()
      {
         setLayout(new FlowLayout());
      	
         button = new JButton("click me");
         button.addActionListener(new Listener());
         add(button);
      	
         label = new JLabel();
         add(label);
      }
   	
       private class Listener implements ActionListener
      {
          public void actionPerformed(ActionEvent e)
         {
            if(e.getSource() == button)
            {
               label.setText("you clicked the button");
            }
         }
      }
   }

what, from this code, goes in the above mentioned methods to get this to run as an applet?
