Hi try this code it will work
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.plaf.basic.*;
public class ToolTipComboBoxExample extends JFrame {
String[] items = {"Swing", "Applet", "RMI", "JDBC"};
String[] tooltips = {"Swing ", "Applet", "RMI", "JDBC"};
public ToolTipComboBoxExample() {
super("ToolTip ComboBox Example");
JComboBox combo = new JComboBox(items);
combo.setRenderer(new MyComboBoxRenderer());
getContentPane().setLayout(new FlowLayout());
getContentPane().add(combo);
class MyComboBoxRenderer extends BasicComboBoxRenderer {
public Component getListCellRendererComponent( JList list,
Object value, int index, boolean isSelected, boolean cellHasFocus) {
if (isSelected) {
setBackground(list.getSelectionBackground());
setForeground(list.getSelectionForeground());
if (-1 < index) {
list.setToolTipText(tooltips[index]);
} else {
setBackground(list.getBackground());
setForeground(list.getForeground());
setFont(list.getFont());
setText((value == null) ? "" : value.toString());
return this;
public static void main (String args[]) {
ToolTipComboBoxExample frame = new ToolTipComboBoxExample();
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
     System.exit(0);
frame.setSize(300, 200);
frame.setVisible(true);
Thanks
