Learn j2me!

sangat jarang sekali programer java di indonesia, pdahal prospeknya bagus lho terutama pemograman di mobile device pake J2Me, bagi kalian yang ingin belajar banyak nih saya kasih bagaimana menampilkan kata “HelloWorld” sebagai awal pertemuan:

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

/**
* contoh menampilkan hello text dan penggunaan exit command
*/
public class HelloCommandMIDlet extends MIDlet implements CommandListener {

private Command exitCommand;
private Command okCommand;
private Command cancelCommand;
private Command nextCommand;
private Command backCommand;
private Display display;

public HelloCommandMIDlet() {
display = Display.getDisplay(this);
exitCommand = new Command(“Exit”, Command.EXIT, 2);
}

public void startApp() {
TextBox t = new TextBox(“Hello”, “Hello World!”, 256, 0);

t.addCommand(exitCommand);
t.setCommandListener(this);

display.setCurrent(t);
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
}

public void commandAction(Command c, Displayable s) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();
}
}

}
