PELAJARAN KITA SEMUA

GAMBARAN UMUM APLIKASI KAMUS JERMAN-INDONESIA

Pada pembuatan aplikasi ini penulis menggunakan bahasa pemrograman Java versi 2 atau sering disebut dengan Java 2. Pada Java 2 terdapat tiga kategori yaitu Java 2 Standard Edition (J2SE), Java 2 Enterprise Edition (J2EE) dan Java 2 Micro Edition (J2ME). Dari ketiga bahasa pemrograman diatas dalam pembuatan aplikasi ini menggunakan Java 2 Micro Edition (J2ME) karena merupakan salah satu bagian dari tehnologi yang dikembangkan untuk memungkinkan aplikasi Java berjalan di perangkat Mobile seperti Telepon genggam, Palm, Pocket PC, dan sebagainya. Di dalam Java 2 Micro Edition (J2ME) terdapat suatu aplikasi yang disebut J2ME Wireless Toolkit yang digunakan untuk pengembangan aplikasi wireless dikarenakan memiliki beberapa emulator untuk menjalankan aplikasi wireless java yang telah dibuat. Pada kesempatan kali ini penulis membuat aplikasi J2ME yaitu kamus jerman- indonesia, yang bertujuan untuk mempermudah pembelajaran bahasa jerman pada aplikasi ini pengguna dapat mencari dari bahasa jerman ke indonesia ataupun sebaliknya.
