Program Sederhan Transaksi Penjualan Toko Komputer dengan Java NetBeans

Assalamu'alaikum wr. wb.

Hai sahabat bloger sekalian, kali ini saya akan membahas tentang "Contoh Program atau Aplikasi Sederhana Transaksi Penjualan Komputer menggunakan Java NetBeans".  kegunaan program ini untuk memudahkan konsumen/kasir memilih Item barang serta mengetahui jumlah total yang harus di bayar. Cek it dot...

Komponen pada Program ini ;

• Konsumen / Kasir
• Item Barang dan Uang / Jumlah Pembayaran

Formula / Penghitungan ;

• Total Paket = Harga Paket*Qty
• Total Custom = Total Proci+Total RAM+Total VGA+Total HDD
• Total Aksesoris = Total Mouse+Total KeyBoard+Total Headset
• Tagihan = Total Paket+Total Custom+Total Aksesoris
• Kembalian = Uang Cash-Tagihan

Step-step pada program ini yaitu;

• Menawarkan Apakan ingin Paket Gaming ?

1. Jika "ya" maka Daftar Paket yang tersedia akan muncul.
2. masukan nomor paket yang di inginkan serta banyaknya.
3. lalu akan muncul paket yang dipilih dan harga satuannya.
4. Total pembelian Paket.
5. jika "tidak" maka ke-step selanjutnya.

• Menawarkan Apakah konsumen ingin Custom?

1. Jika "ya" maka Daftar Item Custom yang tersedia akan muncul, yaitu Proceccor, RAM, VGA, dan HDD. 
2. masukan nomor yang di inginkan serta banyaknya item.
3. kemudian akan muncul item yang dipilih dan harga satuannya
4. Total dari masing-masing item dan Total Pembelian Custom.
5. Jika "tidak" maka ke proses selanjutnya.

• Menawarkan Apakah ingin Membeli Aksesoris Gaming ?

1. Jika "ya" maka akan muncul Daftar Item. Item yang tersedia Mouse, KeyBoard dan HeadSet.
2. Masukan pilihan nomer barang dan banyaknya item
3. Maka akan muncul Item yang di pilih dan harga satuannya.
4. Lalu Total harga Item-item akan muncul serta Total pembelian Aksesoris Gaming.
5. Jika "tidak", maka langsung ke-proses penghitungan Taggihan

• Penghitungan Tagihan

1. Total Paket yang dibeli, Total Custom yang dipilih, dan Total Item Aksesoris.
2. Lalu Total Keseluruhan akan muncul
3. Masukan Uang Tunai konsumen
4. setelah dikalkulasikan maka akan muncul sisa Uang konsumen, Jika kurang akan muncul Uang anda kurang sejumlah sisa Tagihan. jika cukup atau lebih maka akan muncul Uang kembalian dan Ucapan "TERIMA KASIH"
