HomeWork 08 - ATM

ATM (bahasa Indonesia: Anjungan Tunai Mandiri atau dalam bahasa Inggris: Automated Teller Machine) adalah sebuah alat elektronik yang melayani nasabah bank untuk mengambil uang dan mengecek rekening tabungan mereka tanpa perlu dilayani oleh seorang "teller" manusia.

Menggunakan ATM, pelanggan dapat mengakses akun bank mereka untuk membuat penarikan, uang tunai melalui kartu debit, dan memeriksa saldo rekening mereka serta membeli kredit ponsel prabayar . Jika mata uang yang ditarik dari ATM berbeda dengan rekening bank dalam mata uang (misalnya: Penarikan Yen Jepang dari rekening bank berisi Dolar AS), uang tersebut akan dikonversi pada nilai tukar resmi pasar. Dengan demikian, ATM sering memberikan salah satu kemungkinan harga tukar terbaik resmi untuk wisatawan asing, dan juga banyak digunakan untuk tujuan ini.

Sekarang saya akan menunujukkan cara membuat ATM sederhana dengan Java. dengan panduan dari buku “Java How To Program” karya Paul Deitel dan Harvey Deitel.
