Assalamu'alaikum WR.WB. Kali ini saya RONI AREMANIA tentunya hehehe, akan memberikan tutorial Membuat Aplikasi mengitung deret Fibonacci dengan Java.
pertama buat dulu desain kurang lebih seperti gambar ini
untuk tampilan dibikin sederhana dulu
kemudian buat source nya dengan meng-klik button-button yang kita buat tadi
kurang lebih begini
gambar sesuaikan dengan source di bawah ini:
package deretfibonacci;
import javax.swing.table.DefaultTableModel;
public class Fibonacci extends javax.swing.JFrame {
DefaultTableModel tabel=new DefaultTableModel(){
public boolean isCellEditable(int row, int column){
return false;
}
} ;
public Fibonacci() {
initComponents();
tabel.addColumn("Suku Terdahulu");
tabel.addColumn("Suku Kini");
tabel.addColumn("Suku Baru");
tbl.setModel(tabel);
}
private void initComponents() {
jLabel1 = new javax.swing.JLabel();
jLabel2 = new javax.swing.JLabel();
inputderet = new javax.swing.JTextField();
jButton1 = new javax.swing.JButton();
jButton2 = new javax.swing.JButton();
jScrollPane1 = new javax.swing.JScrollPane();
tbl = new javax.swing.JTable();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle("Fibonacci");
setBackground(new java.awt.Color(0, 0, 0));
setCursor(new java.awt.Cursor(java.awt.Cursor.DEFAULT_CURSOR));
getContentPane().setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());
jLabel1.setBackground(new java.awt.Color(204, 204, 0));
jLabel1.setFont(new java.awt.Font("Stencil", 1, 48));
jLabel1.setForeground(new java.awt.Color(0, 0, 204));
jLabel1.setText("DERET FIBONACCI");
getContentPane().add(jLabel1, new org.netbeans.lib.awtextra.AbsoluteConstraints(82, 11, 466, 45));
jLabel2.setFont(new java.awt.Font("Castellar", 0, 14));
jLabel2.setForeground(new java.awt.Color(153, 0, 0));
jLabel2.setText("Jumlah Deret");
getContentPane().add(jLabel2, new org.netbeans.lib.awtextra.AbsoluteConstraints(92, 63, 127, 26));
inputderet.addMouseListener(new java.awt.event.MouseAdapter() {
public void mouseClicked(java.awt.event.MouseEvent evt) {
inputderetMouseClicked(evt);
}
});
inputderet.addActionListener(new java.awt.event.ActionListener() {

}
});
getContentPane().add(inputderet, new org.netbeans.lib.awtextra.AbsoluteConstraints(237, 62, 133, 31));
