Hi Friend,

Try the following code:

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

class StudentAdmissionForm{
public static void main(String[] args) throws Exception{
StudentAdmissionForm sf=new StudentAdmissionForm();
}
public StudentAdmissionForm(){
JFrame f = new JFrame("Frame in Java Swing");
f.getContentPane().setLayout(null);
JLabel lbl1 = new JLabel("Name");
JTextField jt1=new JTextField(15);
JLabel lbl2 = new JLabel("Address");
JTextField jt2=new JTextField(15);
JLabel lbl3 = new JLabel("Gender");

JRadioButton Male,Female;
ButtonGroup radioGroup=new ButtonGroup();
Male=new JRadioButton("Male");
radioGroup.add(Male);
Female=new JRadioButton("Female");
radioGroup.add(Female);
JLabel lbl4=new JLabel("Date Of Birth");
JComboBox combo1=new JComboBox();
JComboBox combo2=new JComboBox();
JComboBox combo3=new JComboBox();
for(int i=1;i<=31;i++){
combo1.addItem(i);
}
for(int i=1;i<=12;i++){
combo2.addItem(i);
}
for(int i=1980;i<=2010;i++){
combo3.addItem(i);
}
JLabel lbl5=new JLabel("Contact No");
JTextField jt3=new JTextField(15);
JLabel lbl6=new JLabel("Select Course");
JComboBox combo=new JComboBox();
combo.addItem("B Tech");
combo.addItem("M Tech");
combo.addItem("MBA");
combo.addItem("MCA");

final JTextArea area=new JTextArea(10,20);
final JScrollPane pane=new JScrollPane(area);

lbl1.setBounds(50,50,70,30);
lbl2.setBounds(50,80,70,30);
lbl3.setBounds(50,110,70,30);

jt2.setBounds(170,80,200,25);
Male.setBounds(170,110,100,30);
Female.setBounds(270,110,100,30);
combo1.setBounds(170,140,50,25);
combo2.setBounds(270,140,50,25);
combo3.setBounds(370,140,80,25);
jt3.setBounds(170,170,200,25);
combo.setBounds(170, 200,100,30);
pane.setBounds(170,240,200,100);

f.add(lbl1);
f.add(lbl2);
f.add(lbl3);
f.add(lbl4);
f.add(lbl5);
f.add(jt1);
f.add(jt2);
f.add(jt3);
f.add(combo1);
f.add(combo2);
f.add(combo3);
f.add(Male);
f.add(Female);
f.add(combo);
f.add(pane);

combo.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
pane.setVisible(true);
ItemSelectable is = (ItemSelectable)e.getSource();
String st= selectedString(is);
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con =DriverManager.getConnection("jdbc:odbc:access","","");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from course where name='"+st+"'");
String strVal="";
while(rs.next()){

ArrayList al = new ArrayList();
al.add("ID= "+rs.getString(1));
al.add("Course= "+rs.getString(2));
al.add("Duration= "+rs.getString(3));
al.add("Fees= "+rs.getString(4));
Iterator itr = al.iterator();
while(itr.hasNext())
{
strVal+= itr.next().toString()+"\n";
}
}
area.setText(strVal);
}
catch(Exception ex){}
}
});

pane.setVisible(false);
f.setSize(1000,1000);
f.setVisible(true);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
static private String selectedString(ItemSelectable is) {
Object selected[] = is.getSelectedObjects();
return ((selected.length == 0) ? "null" : (String)selected[0]);
}
}

For the above code, create table course(id,name,duration,fees).

Thanks
