  public Hello()
{
    super();
}

  public void startApp()
{
    frm = new Form("Hello World");
    String msg = "Hello World.....";
    form.append(msg);
    dis = Display.getDisplay(this);
    dis.setCurrent(form);
  }

  public void pauseApp()
{
}
 
  public void destroyApp(boolean unconditional)
{
    notifyDestroyed();
  }
