Kembali Ke Menu Awal
2. Halaman Menu Materi Pembelajaran
Dalam Pelatihan Java ini ada 3 jenis Operating Sistem (OS) yang akan dijadikan contoh untuk realisasi pemrograman dengan Java
1. Windows
2. Linux
3. On Line
Proses pelatihan juga bisa dilakukan secara on line tanpa harus melakukan instalasi awal terlebih dahulu. Lihat platform on line yang memberikan layanan coding on line ini sebagai berikut
Dengan menggunakan platform on line ini tidak perlu ada instalasi awal yang rumit dan membuang waktu. Prinsip coding bisa dilakukan dengan lebih mudah. Coding hanya dikonsentrasikan pada proses pemahaman struktur bahasa pemrograman saja, tidak perlu hal-hal lain yang hanya menjadi penunjang sekunder aktivitas programming
4. Android
Pada OS berbasis Android yang biasa digunakan di Handphone android terdapat program yang harus diinstalasi di awal program. Untuk latihan pertama ini digunakanlah aplikasi Dcoder yang bisa didownload di Google Play untuk diinstalasi di android. Ada beberapa program lain yang serupa dengan Dcoder yang secara prinsip bisa digunakan juga.
Lihat juga alamat Dcoder yang ada di web On Line
Masing-masing OS memberikan beberapa program awal yang harus diinstalasi di awal program, agar proses programming dapat dilakukan dengan baik. Jika tidak ada program awal yang diinstalasi di masing-masing OS, maka proses programming tidak akan bisa dilakukan.
