Graphic User Interface (GUI) adalah pemrograman dengan bahasa java yang
dibuat menggunakan aplikasi yang berbasiskan GUI. Tujuannya adalah menambahkan
beberapa komponen yang tidak bisa dibuat dalam basis text.
Komponen-komponen tersebut bisa berupa tombol, gambar, dll. Tujuannya adalah
untuk memudahkan user menggunakan program yang dibuat tersebut.
Kalau dilihat pengertian tentang GUI secara umum adalah Interaksi yang
dapat dilaksanakan oleh user melalui menu dan icon yang diperlihatkan dalam
modus grafik. Contoh implementasi GUI-Based Shell ini adalah pada system operasi
Microsoft Windows.
sebelum menambahkan source code, terlebih dahulu kita harus membuat desain kotak dialog nya menggunakan JFrame. lalu setelah itu memasukkan source code nya di kotak source code. contohnya seperti program konversi suhu berikut ini :
package konversi;
/**
*
* @author User
*/
public class NewJFrame extends javax.swing.JFrame {
/**
* Creates new form NewJFrame
*/
public NewJFrame() {
initComponents();
}
/**
* This method is called from within the constructor to initialize the form.
* WARNING: Do NOT modify this code. The content of this method is always
* regenerated by the Form Editor.
