Mungkin Anda telah biasa membuat video player menggunakan VB, Delphi, Foxpro maupun bahasa pemrograman lainnya. Namun bahasa pemrograman diatas hanya dapate berjalan pada aplikasi desktop. Lalu bagaimana kalau kita ingin membuatnya dalam aplikasi mobile?. Nah J2ME dapat menjawab pertanyaannya. Perhatikan skrip berikut:
