Hi Friend,

Try the following code:

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

class Data{
    JLabel l,lab1,lab2;
    JTextField text,text1,text2;
    JButton button;
    Data(){
         l=new JLabel("Enter ID: ");
         text=new JTextField(20);
        JFrame frame=new JFrame();
        frame.setLayout(null);
         button=new JButton("Submit");
         lab1=new JLabel("Name: ");
         text1=new JTextField(20);
         lab2=new JLabel("Address: ");
         text2=new JTextField(20);
        l.setBounds(10,10,100,20);
        text.setBounds(120,10,100,20);
        button.setBounds(120,40,90,20);
        lab1.setBounds(10,70,100,20);
        text1.setBounds(120,70,100,20);
        lab2.setBounds(10,110,100,20);
        text2.setBounds(120,110,100,20);
        lab1.setVisible(false);
        text1.setVisible(false);
        lab2.setVisible(false);
        text2.setVisible(false);

        frame.add(l);
        frame.add(text);
        frame.add(button);
        frame.add(lab1);
        frame.add(text1);
        frame.add(lab2);
        frame.add(text2);
        frame.setVisible(true);
        frame.setSize(500,500);
        button.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e){
                String id=text.getText();
            try{
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
           Connection con = DriverManager.getConnection("jdbc:odbc:student");
           Statement st=con.createStatement();
           ResultSet rs=st.executeQuery("select * from data where id='"+id+"'");
           String name="",address="";
           while(rs.next()){
               name=rs.getString("name");
               address=rs.getString("address");
           }
           text1.setText(name);
           text2.setText(address);
           lab1.setVisible(true);
           text1.setVisible(true);
           lab2.setVisible(true);
           text2.setVisible(true);
           l.setVisible(false);
           text.setVisible(false);
           button.setVisible(false);
            }
            catch(Exception ex){}
            }
        });
    }
    public static void main(String[] args) 
    {
        new Data();
    }
}

Thanks
