    Default 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(); 
      }
     
    }

    What is the desired behaviour, what is the observed behaviour, what are the ideas about possible reasons?
