Cara membuat Aplikasi sederhana menggunakan jFrame java Netbeans

Aplikasi pada desain jFrame kali ini menggunakan control TextField, CheckBox, Button, MenuBar dan jCheckBox (jika tidak di klik, kita tidak bisa mengisi textfield) dengan membuat aplikasi perhitungan jumlah total menu BAKSO MAKENULL.

Untuk lebih mudah dipahami, langsung saja kita akan membuat sebuah program yang sederhana seperti screenshot dibawah ini :

 

Langkah-langkah yang harus dilakukan yaitu :
Pertama buatlah rancangan form di netbeans seperti gambar dibawah ini :

 

Komponen yang terdapat di form tersebut adalah sebagai berikut, ubah nama variable yang diberi kotak hijau itu seperti gambar dibawah ini, atau terserah keinginan kalian yg penting saat kita coding harus sama dengan nama itu :

 Untuk lebih jelasnya pertama-tama pada project klick kanan --> new --> jFrame


Kemudian klik label drak ke layer jFrame -->  klick kanan pada label --> diisi sesuai dengan yang diinginkan. Jika ingin mengedit Font klik font dilayer sebelah kiri --> kemudian edit fontny.. lebih jelasnya lihat gambar.

Di program ini, aturannya adalah jika pilihan menu tidak di centang, maka jTextFieldnya tidak bisa diisi dengan jumlah menu yang dibeli seperti tulisan di awal tadi. Jadi untuk itu jTextFieldnya di hilangkan editablenya.

Caranya sebagai berikut:
Klik kanan pada jTextField --Properties maka akan muncul tampilan seperti dibawah ini :

Hilangkan tanda centang pada editable, selanjutnya di Close.
Selanjutnya pada semua jCheckBox dan jButton yang ada di aplikasi, di klik kanan, pilih Event --> Action --> actionPerformed. Masuk ke bagian Source.

Ketikkan kode program yang tertera pada gambar :

 

 Lanjutkan untuk menu yang lainnya seperti gambar di atas tadi.

Untuk jButtonHitung, ketikkan kode seperti yang tertera pada gambar :



 

 pada jButtonHapus Ketikkan juga kode seperti yang tertera pada gambar :



Kalau sudah selesai langkah-langkah diatas, sekarang tinggal mencoba menjalankan programnya dengan menekan klik kanan pada Project --> Run File atau tekan tombol shift+F6.

 

Beri tanda centrang kemudian diisi sesuai dengan jumlah pesanan menu -- > klik hitung --> jumlah harga secara otomatis terisi seperti gambar :


Klik hapus --> jumlah nilai yang terterara secara otomatis terhapus seperti gambar :


Full Coding program sebagai berikut :
