Program Java Membuat Luas, Keliling dan Volume

1. Buka Aplikasi Netbeans (Saya gunakan Netbeans 6.9.1)
2. Klik New Project
   Pada Categories pilih Java, pada Projects pilih java desktop application
3. Klik Next
4. Pada Project Name ketikkan AplikasiLuasKelilingBangunKotak
5. Kemudian Finish
6. Lakukan Pendesainan seperti gambar berikut:
   
7. Setelah desain sudah jd,,,,pada semua jTextField dan jButton klik kanan dan pada events pilih action<action performed[.....]
   
8. Pada Source ketik codingnya sebagai berikut:
    private void jTextField4ActionPerformed(java.awt.event.ActionEvent evt) {

9. Setelah selesai,,,,Run program tersebut maka akan tampil hasil sebagai berikut :
   
   
10. Klik tombol keluar jika ingin keluar dari hasil run tersebut
11. Hapus angka2 tersebut dan ganti angka2 yg lain serta klik button2 luas,keliling dan volume jika ingin mencoba dengan angka2 lain....
    
    Sekian program yang saya buat....semoga dapat bermanfaat bagi pembaca....kritik dan sarannya saya tampung demi perbaikan program2 saya....
    SELAMAT MENCOBA!!!!
