Here is an example that creates a form in java swing. When the user enters the fields and click the button, the values will get stored into the database.

import javax.swing.*;
import java.awt.*;
import java.io.*;
import java.awt.event.*;
import java.sql.*;
class Form extends JFrame
{
JButton ADD;
JPanel panel;
JLabel label1,label2,label3,label4,label5;
final JTextField text1,text2,text3,text4,text5;
Form(){
label1 = new JLabel();
label1.setText("UserID:");
text1 = new JTextField(20);

label2 = new JLabel();
label2.setText("First Name:");
text2 = new JTextField(20);

label3 = new JLabel();
label3.setText("Last Name:");
text3 = new JTextField(20);

label4 = new JLabel();
label4.setText("ADDRESS:");
text4 = new JTextField(20);

label5 = new JLabel();
label5.setText("Email:");
text5 = new JTextField(20);

ADD=new JButton("ADD");

panel=new JPanel(new GridLayout(6,2));
panel.add(label1);
panel.add(text1);
panel.add(label2);
panel.add(text2);
panel.add(label3);
panel.add(text3);
panel.add(label4);
panel.add(text4);
panel.add(label5);
panel.add(text5);
panel.add(ADD);
add(panel,BorderLayout.CENTER);
setTitle("FORM");
ADD.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae){
String value1=text1.getText();
String value2=text2.getText();
String value3=text3.getText();
String value4=text4.getText();
String value5=text5.getText();
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
        Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root" );
        Statement st=conn.createStatement();

             st.executeUpdate("insert into data(id,fname,lname,address,email) values('"+value1+"','"+value2+"','"+value3+"','"+value4+"','"+value5+"')");
            JOptionPane.showMessageDialog(null,"Inserted Successfully!");
        }
catch(Exception e){}
}
});
}
}
class FormDemo
{
public static void main(String arg[])
{
try
{
Form frame=new Form();
frame.setSize(300,300);
frame.setVisible(true);
}
catch(Exception e){
}
}
}
