Hi Friend,

Try the following code:

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

public class CheckBoxInList{
   public static void main(String args[])   {
      JFrame frame = new JFrame();
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      JList list = new JList(new CheckListItem[] {
            new CheckListItem("1"),
            new CheckListItem("2"),
            new CheckListItem("3"),
            new CheckListItem("4"),
            new CheckListItem("5")});

      list.setCellRenderer(new CheckListRenderer());
      list.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
      list.addMouseListener(new MouseAdapter(){
         public void mouseClicked(MouseEvent event){
            JList list = (JList) event.getSource();
            int index = list.locationToIndex(event.getPoint());
            CheckListItem item = (CheckListItem)
               list.getModel().getElementAt(index);
            item.setSelected(! item.isSelected());
            list.repaint(list.getCellBounds(index, index));
         }
      });   

      frame.getContentPane().add(new JScrollPane(list));
      frame.pack();
       frame.setVisible(true);
   }
}
class CheckListItem{
   private String  label;
   private boolean isSelected = false;

   public CheckListItem(String label){
      this.label = label;
   }
   public boolean isSelected(){
      return isSelected;
   }
   public void setSelected(boolean isSelected){
      this.isSelected = isSelected;
   }
   public String toString(){
      return label;
   }
}
class CheckListRenderer extends JCheckBox  implements ListCellRenderer{
   public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean hasFocus)
   {
      setEnabled(list.isEnabled());
      setSelected(((CheckListItem)value).isSelected());
      setFont(list.getFont());
      setBackground(list.getBackground());
      setForeground(list.getForeground());
      setText(value.toString());
      return this;
   }
}

Thanks
