Thank you for help. l2 is L2 in lower case. I modified the code and
it runs. But it does not work for the second list. Could you try it
and tell me why?

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 ((e.getSource()==l1) && l1.getSelectedIndex()>=0){
            model2.addElement(selection);
            model1.removeElementAt(l1.getSelectedIndex());
     }
     if ((e.getSource()==l2) && l2.getSelectedIndex()>=0){
            model1.addElement(selection);
            model2.removeElementAt(l2.getSelectedIndex());
     }
    }

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