Blog Kelompok 13 TI 2013: Tutorial Pembuatan Program ATM

Assalamualaikum. wr.wb

Kali ini kami akan membahas bagaimana cara pembuatan program ATM dengan menggunakan program Java Eclipse.

Seperti yang kita ketahui eclipse adalah sebuah IDE (Integrated Development Environment) untuk mengembangkan perangkat lunak dan dapat dijalankan di semua platform (platform-independent). Dengan Eclipse, kita dapat membuat berbagai macam aplikasi dengan menggunakan bahasa pemrograman Java. Namun sebelum membuat program, kita harus terlebih dahulu membuat algoritma berupa flowchart dan pseudocode terlebih dahulu. Hal ini dilakukan untuk memaparkan rangkaian cara-cara yang bertahap, sistematis dan logis untuk memecahkan suatu masalah dalam pemrograman.

1.) Flowchart Program ATM

2.) Pseudocode Program ATM

Deskripsi

Nama, tarik, bahasa : String

Pin, saldo,sisa, tes=0 : Integer

Deklarasi

Begin

Read(bahasa)

If bahasa=1 then

bahasa = indonesia

End if

If bahasa = 2 then

bahasa = English

End if

Begin

Read(pin)

tes = tes+1

If tes = 3 then

Write (“ANDA DIBLOKIR”)

End

While (pin>< 1111 or pin><2222 or pin><3333)

If pin = 1111 then

nama = “Cahyo”

saldo = 5000000

End if

If pin = 2222 then

nama = “Tatang”

saldo = 3500000

End if

If pin = 3333 then

nama = “Wati”

saldo = 1750000

End if

Write(nama)

Write(saldo)

Read(tarik)

If tarik = 1 then

sisa = saldo-100000

End if

If tarik = 2 then

sisa = saldo-300000

End if

If tarik = 3 then

sisa = saldo-500000

End if

If tarik = 4 then

sisa = saldo-1000000

End if

If tarik = 5 then

sisa = saldo-1500000

End if

Write(sisa)

End

3.) Tampilan input dan output Program ATM

Setelah memasukkan kartu, pertama kita harus memilih bahasa terlebih dahulu. Misal kita memilih mengguakan bahasa inggris, maka tekan 2 dan enter.

Apabila nasabah memasukkan pin yang salah sebanyak 3 kali, maka kartu ATM akan diblokir

Namun apabila nasabah memasukkan pin yang benar, maka akan muncul pilihan jumlah uang yang akan ditarik. Misal ingin menarik uang sebesar 500.000 maka tekan 3 dan enter.
