Hi Friend,

Try the following code:

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

public class SwingFrame{
public static void main(String[] args) throws Exception{
SwingFrame sf=new SwingFrame();
public SwingFrame(){
JFrame f = new JFrame("Frame in Java Swing");
JLabel lbl1 = new JLabel("Select Course");
final JComboBox jc=new JComboBox();
JLabel lbl2 = new JLabel("Duration");
final JTextField jt1=new JTextField(15);
JLabel lbl3 = new JLabel("Fees");
final JTextField jt2=new JTextField(15);

jc.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
ItemSelectable is = (ItemSelectable)e.getSource();
String st= selectedString(is);
Connection con =DriverManager.getConnection("jdbc:odbc:access","","");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from course where name='"+st+"'");
int duration=0;
int fees=0;
catch(Exception ex){}
static private String selectedString(ItemSelectable is) {
Object selected[] = is.getSelectedObjects();
return ((selected.length == 0) ? "null" : (String)selected[0]);
