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 DateFieldMIDlet extends MIDlet implements CommandListener {

    private Command exitComm;

    private DateField date;
    private DateField time;
    private DateField both;

    private Display display;

    public DateFieldMIDlet() {
        display = Display.getDisplay(this);

        exitComm = new Command("离开", Command.EXIT, 1);

        date = new DateField("日期:", DateField.DATE);
        time = new DateField("时间:", DateField.TIME);
        both = new DateField("时间和日期:", DateField.DATE_TIME);

        java.util.Date now = new java.util.Date();
        date.setDate(now);
        time.setDate(now);
        both.setDate(now);
    }

    public void startApp() {
        Form aForm = new Form("DateField 示范");

        aForm.append(date);
        aForm.append(time);
        aForm.append(both);
        aForm.addCommand(exitComm);
        aForm.setCommandListener(this);
        display.setCurrent(aForm);
    }

    public void pauseApp() {}

    public void destroyApp(boolean unconditional) {}

    public void commandAction(Command c, Displayable s) {
    	
    	String comm = c.getLabel();
    	
        if (comm.equals("离开")) {
            destroyApp(false);
            notifyDestroyed();
        }

    }
