PROGRAM JAVA GUI MENCARI LUAS DAN KELILING LINGKARAN

        Dalam postingan kali ini saya akan membahas tentang cara untuk membuat Program JavaFrame menentukan luas dan keliling lingkaran pada java dengan menggunakan gui.
Anda dapat melihat di bawah ini merupakan kode untuk membuat program tersebut.

    private javax.swing.JTextField jTextField2;
    private javax.swing.JTextField jTextField3;
    private javax.swing.JTextField jTextField4;
    // End of variables declaration

}

dari hasil diatas maka tampilan gui adalah seperti berikut ini :

dari hasil diatas kita coba untuk melakukan running dari data yang telah kita buat,sebagai contoh kita coba memasukkan nama AKKA dengan nilai 89 seperti dibawah ini:

maka setelah kita running atau PROSES maka hasil yang kita dapatkan adalah :

begitu pun sama halnya dengan selanjutnya diman kita hanya memasukkan nama dan nilai saja maka hasilnya akan muncul sesuai dengan rumus yang telah kita buat diatas.
disini untuk menghapus semua tulisan/text dalam textfield kita tinggal klik HAPUS dalam pojok kanan bawah maka semua text akan terhapus,

untuk tombol exit itu akan memudahkan kita untuk keluar dari program secara langsung.

terima kasih....dan selamat mencoba..
kritik dan saran sangat saya nantikan...
