Question about adding multiple components....

Question

.....HI, i really hope someone can help out......
When I try to add mutilple components to the panel, it won't show the components that I have added before again.....
For example, I have a Icon Label and I want it to show two of the same Label again in the panel.... but it won't... it will just show one of them....
for example:
Label[] dice = new Label[6]
Icon bug[] = new Icon[6];
String dicePics[] = {"1.jpg", "2.jpg","3.jpg",
"4.jpg","5.jpg","6.jpg",};
for(int i=0; i<6; i++){
bug[i] = new ImageIcon(dicePics);
dice[i] = new JLabel();
dice[i].setIcon( bug[i] );
userPanel.add(dice[0]);
userPanel.add(dice[0]);
This will only show dice[0] once in panel........ how can I show the same things over again in a panel more then once.........?? I also try it on other things... when adding a component with same name, it will just show one of them.......... wondering if someone can help me out.......

You can't add the same GUI object to a Container multiple times. The problem is with your design. Consider something like this:
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class DieLabelTest {
    private Random rand = new Random();
    private final JLabel[] dies = new JLabel[6];
    DieLabelTest() {
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel diePanel = new JPanel(new GridLayout(3,0,5,5));
        for (int i = 0; i < 6; i++) {
            dies[i] = new JLabel();
            dies.setIcon(DieIconProvider.getIcon(rand.nextInt(6) + 1));
diePanel.add(dies[i]);
f.add(diePanel, BorderLayout.CENTER);
JButton rollButton = new JButton("Roll");
rollButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
for (int i = 0; i < 6; i++) {
dies[i].setIcon(DieIconProvider.getIcon(rand.nextInt(6) + 1));
f.add(rollButton, BorderLayout.SOUTH);
f.pack();
f.setVisible(true);
public static void main(String[] args) {
new DieLabelTest();
class DieIconProvider {
private static Icon[] icons = new Icon[6];
public static synchronized Icon getIcon(int num) {
if (icons[num - 1] == null) {
icons[num - 1] = new ImageIcon(num + ".jpg");
return icons[num -1];
