Having problems with this, can you help?

Question

Hello everyone, I'm currently making a j2me game, I'm still a newbie to it tho.
I'm currently making the splash screen and I've followed a tutorial and intended to make my own, problem now is that there is something wrong with the code and is not working as I thought it would. Can you guys check what's wrong with my code? And please advise me on what's wrong and how do I fix it. Thanks alot. The code is below. The Sscreen.java is the one responsible for making and showing the splash screen while the Main.java is the main midlet and calls Sscreen.java.
// Sscreen.java
import java.util.Timer;
import java.util.TimerTask;
import javax.microedition.lcdui.*;
public final class Sscreen extends Canvas
     private Display dis;
     private Displayable nxt;
     private Timer tmer;
     private Image im;
     public Sscreen(Display dis,Displayable nxt,Image im)
          tmer=new Timer();
          this.dis=dis;
          this.nxt=nxt;
          this.im=im;
          dis.setCurrent(this);
     private void dismiss()
          tmer.cancel();
          dis.setCurrent(nxt);
     protected void keyPressed(int keyC)
          dismiss();
     protected void paint(Graphics g)
          g.setColor(0x00000000);
          g.fillRect(0, 0, getWidth(), getHeight());
          g.setColor(0x00000000);
          g.drawImage(im,getWidth()/2,getHeight()/2-5,3);
     protected void showNotify()
          tmer.schedule(new Counter(), 3000);
     private class Counter extends TimerTask
          public void run()
               dismiss();
// Main Class
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class Main extends MIDlet
     private Display dis;
     private Image im;
     private boolean Splash=true;
     public Main(){}
     protected void destroyApp(boolean arg) throws MIDletStateChangeException {
          notifyDestroyed();     
     protected void pauseApp() {     }
     protected void startApp() throws MIDletStateChangeException {
          dis=dis.getDisplay(this);
          if(Splash)
               Splash=false;
               try
                    im=Image.createImage("/bg.png");
                    new Sscreen(dis,new Temp(),im);
               catch(Exception e)
                    System.out.println("Prob 2");
     class Temp extends Form implements CommandListener
          private Command exitCommand = new Command("Exit", Command.EXIT, 1 );
          public Temp()
               super("Main");
               addCommand( exitCommand );
     setCommandListener( (CommandListener) Main.this );
          public void commandAction(Command arg0, Displayable arg1) {
               notifyDestroyed();
}

Answer 1

i think problem is here
*setCommandListener( (CommandListener) Main.this );*instead use
setCommandListener(this );
