Selection of JList item

Question

hi friends
i am using JList component.i have added many item in Jlist.by keyboard up and down arrow key i can make them highlighted and then select. but i want few item of JList never highlighted and select when i press up and down arrow key . For example, If i do not want to select 2nd item in the list then by pressing down arrow key selection should be jumped from first to third item skipping second item.
How to do that?

I might be wrong but I think you need to code for it.
I have created a code using key binding. To use if you need to skip an item you need to hold down the control key and use the up and down arrow to navigate and once you have selected an item release control key and press enter, vice-versa.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class ListFocusDemo extends JFrame {
    public void createAndShowUI() {
        final JList myList = new JList(new String[] {"My data 1","My data 2",
        "My data 3","My data 4"});
        JScrollPane scrollPane = new JScrollPane(myList);
        InputMap map = myList.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
        map.put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "myAction");
        myList.getActionMap().put("myAction", new AbstractAction() {
            public void actionPerformed(ActionEvent evt) {
                int lead = myList.getLeadSelectionIndex();
                if(lead > -1 && !myList.isSelectedIndex(lead)) {
                    myList.getSelectionModel().addSelectionInterval(lead, lead);
                } else if(lead > -1 && myList.isSelectedIndex(lead)) {
                    myList.getSelectionModel().removeSelectionInterval(lead, lead);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        getContentPane().setLayout(new BorderLayout());
        getContentPane().add(scrollPane, BorderLayout.CENTER);
        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    public static void main(String[] args) {
        Runnable run = new Runnable() {
            public void run() {
                new ListFocusDemo().createAndShowUI();
        SwingUtilities.invokeLater(run);
}
