Hi Friend,

Try the following code:

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

public class SplitPaneExample {
public static void main(String[] args){
JFrame frame = new SplitPaneFrame();
frame.show();
}
}
class SplitPaneFrame extends JFrame implements ListSelectionListener{
public SplitPaneFrame(){
setSize(400, 300);
list = new JList(texts);
list.addListSelectionListener(this);
description = new JTextArea();
JSplitPane innerPane= new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, list, description);
getContentPane().add(innerPane, "Center");
}
public void valueChanged(ListSelectionEvent event) { JList source = (JList)event.getSource();
Display value = (Display)source.getSelectedValue();
description.setText(value.getDescription());
}
private JList list;
private JTextArea description;
private Display[] texts =
{ new Display("Text1", "This is text1."),
new Display("Text2", "This is text2."),
new Display("Text3", "This is text3."),
new Display("Text4", "This is text4.")
};
}
class Display{
public Display(String n, String t){
name = n;
des = t;
}
public String toString(){
return name;
}
public String getDescription(){
return des;
}
private String name;
private String des;
}

Thanks
