UTS Pemprograman 2 Aplikasi Sederhana Penyewaan Barang Elektronik Menggunakan Java di SASMITO STORE

Hello World!, perkenalkan saya Al Moslem ingin memposting UTS Pemprograman 2 dimana harus diupload di blogspot untuk mendapatkan nilainya dan yuk kita simak aja!

Nama  : Al Moslem Bintang Sasmito
Nim    : 171021400158

Ini contoh aplikasi yang saya buat, penyewaan barang elektronik di toko bernama SASMITO STORE

Penjelasan Program

Program yang saya buat ini adalah untuk memudahkan pelanggan yang ingin melakukan transaksi penyewaan di toko SASMITO STORE, dimana harapan saya pelanggan dan penjual akan dimudahkan prosesnya jika menggunakan program yang dibuat ini .

FlowChart

Screenshot Program

Inilah Screenshot saat program dijalankan

Setelah program dijalankan, pilih menu barang dengan klik panah dan akan muncul harga sewa per 1 hari nya, selanjutnya isikan lama hari sewa dengan angka 1 sampai berapa hari kamu ingin sewa dicontoh kita misalnya ingin sewa 3 hari maka ketikan "3" tanpa tanda petik

Setelah di isikan data nya, pilih TOTAL untuk menghitung berapa total harga barang yang ingin anda isi dan BATAL untuk menghapus pilihan sebelumnya kalau belum yakin barangnya sesuai, karena saya sudah yakin ingin menyewa Kamera selama 3 hari maka saya klik TOTAL dan TOTAL HARGA akan muncul seperti ss di bawah "450.000"

Selanjutnya setelah mengetahui harga sewanya, kita bayarkan uang dengan cara ketikan uang anda di UANG BAYAR dan klik BAYAR untuk melakukan pembayaran misalnya saya mempunyai uang "500.000 Rupiah" maka ketikan "500000"

Dan klik button BAYAR maka akan muncul uang kembalian anda

selanjutnya klik button BATAL untuk melakukan transaksi ulang, atau button SELESAI untuk keluar program

ini contoh setelah di klik button BATAL

dan button SELESAI untuk keluar dari program, dan program akan tertutup.
