Hi Friend,

Try the following code:

import java.awt.*;
import java.sql.*;
import javax.swing.*;
public class MultipleJCombo{

public MultipleJCombo(){
JFrame f = new JFrame("Frame in Java Swing");
JLabel label1=new JLabel("Qualification");
JLabel label2=new JLabel("Specialization");
JComboBox jc1=new JComboBox();
JComboBox jc2=new JComboBox();
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con =DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root";);
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from user_details");
jc1.addItem("Select");
jc2.addItem("Select");
while(rs.next()){
jc1.addItem(rs.getString("qualification"));
jc2.addItem(rs.getString("specialization"));
}
}
catch(Exception e){
}
JPanel p=new JPanel(new GridLayout(2,2));
p.add(label1);
p.add(jc1);
p.add(label2);
p.add(jc2);
f.add(p);
f.setVisible(true);
f.pack();

}
public static void main(String[] args) throws Exception{
MultipleJCombo sf=new MultipleJCombo();
}
}

Thanks
