Thread: What is wrong with my code

I was following a tutorial exactly, i made sure everything looked the same but it still doesnt work.
I am using the latest version of NetBeans 7.3.1

package javagame;
 
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyAdapter; 
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
 
public class JavaGame extends JFrame {
 
    int x, y;
    private Image dbImage;
    private Graphics dbg;
 
    public class AL extends KeyAdapter {
        public void KeyPressed(KeyEvent e){
           int KeyCode = e.getKeyCode();        
           if(KeyCode == e.VK_LEFT) {
              x--;
           }
           if(KeyCode == e.VK_RIGHT) {
               x++;
           }
            if(KeyCode == e.VK_UP) {
               y--;
           }
             if(KeyCode == e.VK_DOWN) {
               y++;
 
           }
    }
    public void KeyReleased (KeyEvent e) {
 
    }   
  }
  public JavaGame (){
    addKeyListener(new JavaGame.AL());    
    setTitle("Java Game");
    setSize(500, 500);
    setResizable(true);
    setVisible(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
    x = 150;
    y = 150;
}
 
  public void paint(Graphics g){
      dbImage = createImage(getWidth(), getHeight());
      dbg = dbImage.getGraphics();
      paintComponent(dbg);
      g.drawImage(dbImage, 0, 0, this);
  }
 
  public void paintComponent(Graphics g){
      g.fillOval(x, y, 15, 15);
      repaint(); 
  }
 
  public static void main(String[] args){
      new JavaGame(); 
  }
 
}
