public class a extends MIDlet {
public Display display;
public game abc;
public a() {


// TODO Auto-generated constructor stub
}

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {

System.out.println("GAme ended");

}

protected void pauseApp() {
// TODO Auto-generated method stub

}

protected void startApp() throws MIDletStateChangeException {
// TODO Auto-generated method stub
display=Display.getDisplay(this);
try
{
b abc=new b();
abc.start();
display.setCurrent(abc);
}

catch(Exception e)
{

}


}

}
