Membuat Aplikasi Tiket Bus Dengan Java NetBeans

A. Deskripsi

    Aplikasi Tiket Bus
Aplikasi ini dibuat untuk memudahkan user ketika ingin mengetahui harga Tiket Bus sebelum memesan sehingga bisa mempersiapkan uang pas. Program ini cukup sederhana, Pengguna Tinggal pilih Rute Bus yang di tuju  lalu akan muncul harga tiket satuan jikalau pengguna ingin membeli tiket lebih dari satu, pengguna tinggal menggunakan item Combobox yang berisi 1-4 lalu akan muncul harga total setelah itu centang kotak checkbox untuk mendapatkan diskon8% kemudian pengguna tekan tombol button utuk mengetahui harga yang harus dibayar,  didalam aplikasi ini juga terdapat item - item sebagai berikut :

7 label
4 RadioButton
1 ButtonGrup
4 TextField
1 checkBox
1 Button

C. Screen Shoot

   Berikut Proses Pembuatan Aplikasi Info Tiket Bus :

Langkah awal anda harus membuat terlebih dahulu Project Baru

- Langkah pertama jalankan java NetBeans pada komputer

- Pilih File > New Project > Finish

- Setelah itu beri nama Projectnya lalu klik finish

- Lalu Klik kanan pada project Tiket bus >New>JFrameFrome

Kemudian Desainlah Frame Seperti berikut :

- Lalu ubahlah Variabel Name dari item item yang ada di disain sebagai berikut :

 JRadioButton1 = RB1             JComboBox = CmbJum
 JRadioButton2 = RB2             JCheckBox = ChkDiskon
 JRadioButton3 = RB3             Button = BtBayar
 JRadioButton4 = RB4
 Button Grup = BgTujuan

JTextfield1 = TxtHarga
JTextfield2 = TxtTotal

JTextfield1 = TxtDiskon

JTextfield1 = TxtBayar

- Setelah Itu berikan Source Code, Yang nanti akan saya Sampaikan dibagian Akhir.

- Setelah Selesai proses Coding. Klik Run > Run File.

- Kemudian Akan Muncul Seperti Ini

- Jika Coding Yang Anda lakukan benar, Maka hasilnya akan seperti ini
