Disini saya ingin mengenalkan program "Restoran Lama Saji" yang saya buat untuk memenuhi tugas di semester saya yang kedua di STMIK Eresha. Saya membuat program ini dengan software Netbeans 8.2.
Di program saya ini ,saya membuat 3 menu. yang pertama menu makanan ,yang kedua payment (pembayaran) dan ketiga itu exit atau dalam hal ini running program nya terhenti.
Pertama, kita perlu memilih menu makanan. Karena jika memilih payment ,maka akan kembali ke menu awal.
Kedua, pilih menu yang tersedia ,ada 5 pilihan yaitu :
-Nasi+Ayam Bakar+Teh Manis
-Nasi+Lele Goreng+Teh Manis
-Nasi Goreng
-Gado-Gado+Aqua
-Ice Cream
Ketiga,setelah memilih menu yang di inginkan lalu input jumlah menu yang di inginkan min. 1 dan maks. 10
Keempat,sesudah memesan ,maka tampilan akan kembali ke menu awal. karena menu payment(pembayaran) ada di menu awal
Kelima, setelah memilih menu payment(pembayaran) maka akan tampil menu makanan yang sudah di pilih dan jumlah yang telah di pesan
Keenam, masukkan jumlah uang yang harus di bayarkan dan usahakan lebih dari total pembayaran ,karena jika kurang maka akan mengulang terus menerus hingga uang pembayaran nya pas atau lebih
Ketujuh, jika sudah selesai. anda akan kembali ke menu awal ,jika ingin memesan kembali maka ikuti petunjuk Kedua sampai Ketujuh jika tidak maka pilih menu exit.
Dibawah ini adalah tampilan flowchart Restoran Lama Saji :
