Hi Friend,

Try this:

import java.awt.*;
import java.sql.*;
import javax.swing.*;
import java.awt.event.*;
class  FormData{

    public static void main(String[] args){
    JFrame f=new JFrame();
    JLabel label1=new JLabel("Name: ");
    JLabel label2=new JLabel("Date Of Birth: ");
    JLabel label3=new JLabel("Address: ");
    JLabel label4=new JLabel("Contact No: ");
    final JTextField text1=new JTextField(20);
    final JTextField text2=new JTextField(20);
    final JTextField text3=new JTextField(20);
    final JTextField text4=new JTextField(20);
    JButton b=new JButton("Save");
    b.addActionListener(new ActionListener(){
        public void actionPerformed(ActionEvent e){
        String v1=text1.getText();
        String v2=text2.getText();
        String v3=text3.getText();
        int v4=Integer.parseInt(text4.getText());

        try{
           Class.forName("com.mysql.jdbc.Driver");
           Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
           Statement st=con.createStatement();
           int i=st.executeUpdate("insert into data(name,dateOfBirth,address,contactNo) values('"+v1+"','"+v2+"','"+v3+"',"+v4+")");
           JOptionPane.showMessageDialog(null,"Data is inserted successfully");
        }
        catch(Exception ex){
            System.out.println(ex);
        }
        }
    });
        JPanel p=new JPanel(new GridLayout(5,2));
        p.add(label1);
        p.add(text1);
        p.add(label2);
        p.add(text2);
        p.add(label3);
        p.add(text3);
        p.add(label4);
        p.add(text4);
        p.add(b);
        f.add(p);
        f.setVisible(true);
        f.pack();
    }
}

Thanks
