Hi Friend,

Try the following code:

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

class AddComboBoxItem{

AddComboBoxItem(){
JComboBox combo=new JComboBox();
JFrame f=new JFrame();
JPanel p=new JPanel();
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("jdbc:odbc:access");
Statement st=conn.createStatement();
ResultSet rs=st.executeQuery("Select coursename from course");
while(rs.next()){
combo.addItem(rs.getString("coursename"));
}
}
catch(Exception e){}
p.add(combo);
f.add(p);
f.setVisible(true);
f.setSize(300,100);
}
public static void main(String[] args)
{
AddComboBoxItem add=new AddComboBoxItem();
}
}

Thanks
