public class MyGauge extends MIDlet implements CommandListener {
        Display display;
        int i=0;
        Command start=new Command("Start",Command.SCREEN,1);
        Form frm=new Form("");
        Gauge gauge = new Gauge ("Loading... Please wait.",false,7,0);
        public MyGauge() {
                display = Display.getDisplay(this);
                frm.addCommand(start);
                frm.append(gauge);
                display.setCurrent(frm);
                frm.setCommandListener(this);
        }
