Cara membuat radio butten masukan 3 radio button ke layout desain kemudian klik kanan edit text,sesua yang di inginkan dan kemudian masukan 1 button group klik di radio button dan cari button group ada di bagian kanan netbeans klik combonya rubah "none"menjadi button group yang di ingin kan & lakukan pada setiap radio butten

  • Cara Membuat Combo box  masukan combo box ke layout dan klik kanan propertis cari model edit kata atau bilangan yang mau di masukan closs layer 
  • Cara Membuat Fungsi Event KeyPressed,klik kanan Event Key klik KeyPressed 
  • Cara Membuat windoesClosing klik kanan propertis Event cari windowsClosing tutup Layout copy text ini di bawah public voiid widowsClosing
  •     int exitApp= JOptionPane.showConfirmDialog(null,
                "Apakah Ingin Menutup Aplikasi?", "Konfirmasi", JOptionPane.YES_NO_OPTION);
                if (exitApp==JOptionPane.YES_OPTION){
                System.exit(0);
                }
  • Cara agar layout tak tertutup saat di Closs,klik kanan propertis cari tulisan defaultCloseOperation    EXIT_ON_CLOSE
