j2me接口的例子,很不错的东东 可以做教程

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

public class AppendTicker extends MIDlet implements CommandListener {

    private Command exitCommand;

    private Display display;

    public AppendTicker() {
        display = Display.getDisplay(this);
        exitCommand = new Command("离开", Command.EXIT, 1);
    }

    public void startApp() {
        TextBox t = new TextBox("Hello",
                                "Welcome to MIDP Programming", 256, 0);
        Ticker aTicker = new Ticker("从绝望中寻找希望！");
        t.setTicker(aTicker);
        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();
        }
    }
}
