    Question Help removing JFrame inheritance

    Hi, I'm new-ish to java so please excuse any mistakes I make. Please Ignore stuff in brackets:[I've been making a dice game That when you press space, the dice "rolls" and a random number is generated. I've been trying to add the class to an html as an applet. I read somewhere that I had to Extend JApplet, but since I already extended JFrame I Can't extend Both. Can and I remove the JFrame inheritance and make my code work with JApplet? if so, How?]
    Code so far:
    EDIT: OK, I think I figured out what I'm supposed to do, but it doesn't display in my browser. Here's my new code:
    import java.awt.FlowLayout;
    import java.awt.BorderLayout;
    import java.awt.Container;
    import java.awt.Dimension;
    import javax.swing.*;
    import java.awt.event.*;
    import java.applet.*;
     
    public class DiceGameApplet extends JApplet
           implements KeyListener,
           ActionListener
    {
    	private JLabel label2 = new JLabel();
        JTextArea displayArea = new JTextArea();
        int width, height;
        JButton button = new JButton("Clear");
        JScrollPane scrollPane = new JScrollPane(displayArea);
        Icon DiceGame = new ImageIcon( getClass().getResource( "dice.gif" ) );
     
        static final String newline = System.getProperty("line.separator");
     
    	    public void init() {
            width = getSize().width;
            height = getSize().height;
    	    button.addActionListener(this);
    	    displayArea.setEditable(true);
    	    displayArea.addKeyListener(this);
    	    scrollPane.setPreferredSize(new Dimension(375, 125));
    	    getContentPane().add(scrollPane, BorderLayout.CENTER);
    	    getContentPane().add(button, BorderLayout.PAGE_END);
    		setLayout( new FlowLayout() );
    		label2.setText( "" );
    		label2.setIcon( DiceGame );
    		label2.setToolTipText( "DiceGame" );
    		label2.setHorizontalTextPosition( SwingConstants.LEFT );
    		label2.setVerticalTextPosition( SwingConstants.BOTTOM );
    		add( label2 );
        }
     
    	    public void keyTyped(KeyEvent e) {}
    	    public void keyPressed(KeyEvent e) {
    		    if(e.getKeyChar() == e.VK_SPACE) {
    		       int d = (int)(Math.random() * 10) % 6 + 1;
    		       displayInfo(d);
    	        }
    		    displayArea.requestFocusInWindow();
    	    }
    	    public void keyReleased(KeyEvent e) {}
     
    	    public void actionPerformed(ActionEvent e) {
    		     displayArea.setText("");
    		     displayArea.requestFocusInWindow();
            }
     
            private void displayInfo(int g){
    			displayArea.setText("");
    		    String keyString = Integer.toString(g);
                displayArea.append(keyString + newline);
                displayArea.setCaretPosition(displayArea.getDocument().getLength());
        }
    }
    What's Wrong with it?
    Thanks in advance!

    If you're putting it on the web, then you don't need a JFrame. Frames and applets cancel each other out.
    Please use [highlight=Java]//code goes here...[/highlight] tags when posting your code
