Tugas PBO Remote TV

Tugas PBO Remote TV

Pada kesempatan kali ini, saya mencoba membuat sebuah remote TV dengan menggunakan Java. Remote TV memiliki beberapa method, yakni,

1. Nyalakan Tivi

2. Tambah Channel

3. Kurangi Channel

4. Set Channel

5. Tambah Volume

6. Kurangi Volume

Apabila Tivi mati maka semua method tersebut tidak dapat digunakan, dan tidak ada channel negatif.

Contoh Output seperti berikut:

 Dari Output diatas, saya menggunakan metode clrscreen untuk tetap memberikan 1 layar tivi dan 1 remote tv, dengan code "System.out.print('\u000C');"
Berikut diagram classnya:

Melihat tivi melalui kelas lihat tv, sedangkan layar diperoleh dari kelas tv, dan interaksi didapat dari kelas remote, berikut source code nya
