Gan ingin mencoba

ini coding java nya:
Name : Latihan1
Class : Dedi

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

public class FirstList extends MIDlet implements CommandListener{
        Display display;
        List list,lEx,lMu,lIm;
        Image img;

            try{
                        img = Image.createImage("/Icon/App.png");
            }catch (java.io.IOException e){
                System.out.println("error gambr: " + e);
            }
            cmBack = new Command("Kembali",Command.BACK,1);

                case 2:

        }else if(c == cmExit){
                   exitMIDlet();

            }
       }
        public void exitMIDlet(){
            destroyApp(false);
            notifyDestroyed();
        }
}

selesai 

langkah selanjutnya

buka Weireless toolkit
pilih settings, Required, MIDlet-Name ganti dengan nama Latihan 1
untuk mendukung aplikasi dalam hp bentuk Jar
kemudian pilih Project 
Package > createpackage
selesai dehhh
copy-paste in aja ke hp kamu..
selamat mencoba....
