Thank you for the msg. Below is the code.  It can move the names from
the left to the right if you click the name.  How can I move the name
from the right to left?  The listener is the class, so I am not sure
how to get 2 listeners.

import java.awt.*;
import javax.swing.event.*;
import javax.swing.*;

public class List2 implements ListSelectionListener
{
JList l1,l2;
DefaultListModel model1 = new DefaultListModel();
DefaultListModel model2 = new DefaultListModel();
 public static void main(String[] args) {
   JFrame f = new JFrame("Lister v1.0");
   List2 l=new List2();
   f.setSize(200, 200);
   f.setLocation(200, 200);
    Container c = f.getContentPane();
    GridLayout grd = new GridLayout(1,2,10,10);
    c.setLayout(grd);
   l.create();
   c.add(l.l1);
    c.add(l.l2);
   f.setVisible(true);
     }

public void valueChanged(ListSelectionEvent e){
       Object selection = l1.getSelectedValue();
       if (l1.getSelectedIndex()>=0){
           model2.addElement(selection);
           model1.removeElementAt(l1.getSelectedIndex());
   }}

private void create(){
    l1 = new JList(model1);
    l2 = new JList(model2);
    model1.addElement("Mark");
    model1.addElement("Mary");
    model1.addElement("Mike");
    l1.addListSelectionListener(this);
 }}
