Assalamualaikum

Kali ini saya memposting tugas uas Algoritma dan Pemprograman 2 ,
disini saya membuat aplikasi sederhana menggunakan Netbeans yaitu program dari sebuah restoran.

2.1
Aplikasi ini dibuat dengan Netbeans dan terhubung dengan data base menggunakan MySQL , dimana user diminta memasukan id pesanan yang sudah tersedia pada kolom di sebelah kanan , setelah itu automatis akan menampilkan menu pesanan , setelah itu masukan jumlah pesanan maka akan tampil harga total . selanjut nya klik save untuk menyimpan pesanan.
2.2
Komponen yang ada dalam aplikasi saya terdiri dari :
- ID
- Jumlah Pesanan
- Menu
- Harga
- Harga Total
- Close
- New
- Save
- Refresh
- Pesan
- Delete

2.3
Berikut adalah screenshoot dari jframe dan aplikasi ketika di run :

Terima Kasih Sudah Berkunjung .
Ini adalah source code program saya
