Konverter Mata Uang
Pada project kali ini kami berdua membuat sebuah aplikasi yang dapat membantu banyak orang yang mungkin pada saat orang tersebut lagi tidak ada di negeri tersebut, maka aplikasi yang kami akan membantu mereka. Anggota yang membuat project ini adalah :
- Muhammad Naufaldillah - 05111940000202
- Aji Rindra Fakhrezi Putra Faisal - 05111940000205
Asal mula kami memikirkan untuk membuat project ini adalah, banyak orang yang berpergian untuk keluar negeri dan yang pastinya di luar negeri akan mengeluarkan beberapa uang yang dibawanya. Oleh karena itu, orang-orang yang berpergian akan melakukan perhitungan pada saat diluar negeri untuk mengeluarkan berapa banyak uang yang akan dikeluarkan. Maka dari itu kami membuat aplikasi Konverter Mata Uang, dengan aplikasi ini para pengguna bisa mengetahui berapa banyak nominal yang mereka akan keluar dalam bentuk mata uang negara lain. Aplikasi ini dapat membantu para pengguna untuk merencanakan berapa banyak uang yang akan dikeluarkan. Aplikasi ini hanya memiliki satu class :
- CurrencyConverterClass.java : merupakan class utama yang berisikan JFrame untuk windowsnya dan algoritma untuk menghitung berapa nominal yang akan di hitung menjadi mata uang yang diinginkan
