Belajar J2ME, J2ME merupakan bagian dari java yang di khususkan untuk berjalan di perangkat micro. Seperti layaknya bahasa pemrograman yang lain midlet istilah dalam pemrograman java sudah diperkaya dengan fasilitas untuk menangani file-file gambar baik yang berextensi jpg,bmp,png. Disini kita akan membuat slide gambar dimana apabila tombol navigasi hp ditekan maka akan muncul gambar berikutnya sesuai data gambar yang dijadikan slide. Berikut sample image slide dalam midlet.

Berikut Sourcenya
