Assalamu’alaikum… :)
Disini saya akan berbagi
tentang penerapan Program JAVA menggunakan NetBeans dan sekaligus untuk
memenuhi tugas UTS “ALGORITMA DAN PEMROGRAMAN”.
Contohnya pembuatan form
“Penjualan Laptop” seperti gambar berikut.
Ini adalah gambar Source Codingnya..!
Source Codingnya yaitu:
public class Tryagain
extends javax.swing.JFrame {
/**
* Creates new form Tryagain
*/
public Tryagain() {
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.
*/
