Regarding Animation

Question

Currently i want to make a WALKING animation with 2 image file.
I had try to use the callSerially(this) to help me, but it does not work.It shows error when i run the application.
The following are what i had typed out.(it uses the class of one of the examples given by java.sun.com).
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class AnimationExample extends MIDlet
     Image[] img;
     Display display;
     public void startApp()
          try{
          img[0] = Image.createImage("/Right_Movement_Frame_1.png");
          img[1] = Image.createImage("/Right_Movement_Frame_7.png");
          }catch(Exception e){
          System.out.println(e.getMessage());}
          display = Display.getDisplay(this);
          display.setCurrent( new Animation(img));
     public void pauseApp()
     public void destroyApp(boolean unconditional)
     public class Animation extends Canvas implements Runnable
     private Image[] frames;
     private int next = 0;
     private boolean go = false;
     public Animation( Image[] frames )
     this.frames = frames;
     protected void paint( Graphics g )
     g.drawImage( frames[next], 0, 0,
     g.TOP | g.LEFT );
     public void startAnimation()
     go = true;
     repaint();
     display.callSerially( this );
     public void stopAnimation()
     go = false;
     public void run()
     if( go )
     if( ++next >= frames.length ) next = 0;
     repaint();
     display.callSerially( this );
Does anyone has an idea why it does not work. Please help me on this problem.
Thank You
