Contoh Program Sederhana JComboBox :

import javax.swing.*;

public class ComboBoxTest extends JFrame {

                    private JComboBox cmbImage;

                    private JLabel label;

                    private String arrGambar[] = {"Blushing.png", "Cool.png", "Happy.png","Smile.png","Winking.png"};

                    private Icon arrIcon[] = { new ImageIcon(arrGambar[0]),

                                                                                    new ImageIcon(arrGambar[1]),

                                                                                    new ImageIcon(arrGambar[2]),

                                                                                    new ImageIcon(arrGambar[3]),

                                                                                    new ImageIcon(arrGambar[4])

                                                                                  };

                    public ComboBoxTest() {

                                         super ("Mencoba Combo Box");

                                         Container container = getContentPane();

                                         container.setLayout(new FlowLayout());

                                         cmbImage = new JComboBox (arrGambar);

                                         cmbImage.setMaximumRowCount(3);

                                         cmbImage.addItemListener(

                                                             new ItemListener() {

                                                                                 public void itemStateChanged (ItemEvent e) {

                                                                                                      if (e.getStateChange() == ItemEvent.SELECTED)

                                                                                                                          label.setIcon(arrIcon[cmbImage.getSelectedIndex()]);

                                                                                 }

                                                             } //end anonimous inner class

                                         );

                                         container.add(cmbImage);

                                         label = new JLabel (arrIcon[0]);

                                         container.add(label);

                                         setSize (350,400);

                                         setLocationRelativeTo(null);

                                         setVisible(true);

                    }

    public static void main (String args[]) {

                    ComboBoxTest test = new ComboBoxTest ();

                    test.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

} //end of clas

oh iya... nama gambar harus sesuai dan berada di dalam folder bersama program java ini... :D
