PBO: UTS "GTO"

Rancangan Class dan Penjelasan:

• TempelKartu

• Class ini berfungsi sebagai perantara antara user dan database.

• TotalAkun

• Class ini berfungsi sebagai pemroses data untuk single user.

• GTODatabase

• Class ini berfungsi sebagai pemanggil proses yang ada di TotalAkun.

• Keypad

• Class ini berfungsi sebagai pengatur segala inputan.

• Layar

• Class ini berfungsi sebagai penampil berbagai hasil yang di outputkan oleh system.

• GTO

• Class ini adalah pengatur utama dalam penerapan sistem GTO.

• RunProgram

• Class ini sebagai pemicu program utama.

Rancangan Output:

Output yang dihasilkan dari program ini adalah:

• Jika saldo>=Harga e-toll:

• nama perusahaan
• tanggal transaksi
• harga e-toll
• sisa saldo e-toll

• Jika saldo<Harga e-toll:
• Output string "Saldo tidak mencukupi"
