public class HelloMIDlet extends MIDlet {
public void startApp() {
System.out.println("Hello World");
public void pauseApp() {
public void destroyApp(boolean unconditional) {

public class TestMidlet extends MIDlet implements CommandListener {
    TextBox tb;
    Command cmdExit;
    Display dsp;
    public TestMidlet(){
        tb = new TextBox("My first application", "Hello World", 100, TextField.ANY);
        cmdExit = new Command("Exit", Command.EXIT, 0);
        tb.addCommand(cmdExit);
        tb.setCommandListener(this);       
        dsp = Display.getDisplay(this);
    public void startApp() {
        dsp.setCurrent(tb);
    public void pauseApp() {
    public void destroyApp(boolean unconditional) {
    public void commandAction(Command cmd, Displayable arg1) {
        if(cmd == cmdExit){
            notifyDestroyed();
            destroyApp(true);
}
