How to create a swing application with multiple pages

Question

Earlier I have created a small application using servlets where the first page shows a user registration page that captures basic information like user's first name and last name etc. with a Submit button.

Let's say the user first name entered in first page is "Scott" then once the user submits the form then in second page I have created a welcome message as "Welcome Scott". Then I provided an option to see list of users who have registered to the application earlier by connecting to database.

Now I wanted to implement the same in Swing application. I am new to Swings so I tried to learn it from various sources but I was not able to find an example where I can navigate between multiple frames/panels.

For the first page I have created below program that displays the text fields and a submit button:

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;

public class UserRegistration extends JFrame {

    JButton button;

    public UserRegistration() {

        setSize(300,300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new FlowLayout());

        final JLabel label = new JLabel("Please enter details: ");
        JLabel firstName = new JLabel("First Name");
        JLabel lastName = new JLabel("Last Name");
        final JTextField firstNameTxt = new JTextField(20);
        final JTextField lastNameTxt = new JTextField(20);

        button = new JButton("Submit");
        JButton button1 = new JButton("Cancel");

        button.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e) {
                dispose();
                UserDetails user = new UserDetails();
                user.showDetails();
                user.setVisible(true);
            }
        });

        add(label);
        add(firstName);
        add(firstNameTxt);
        add(lastName);
        add(lastNameTxt);
        add(button);
        add(button1);

        setVisible(true);

    }
    public static void main(String args[]) {
        new UserRegistration();
    }

}

To go from 1st frame to 2nd frame I am using these lines:

                dispose();
                UserDetails user = new UserDetails();
                user.showDetails();
                user.setVisible(true);

Now for second page I am not able to find out how to get the parameters the user has entered, this is the code that I am stuck at:

import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class UserDetails extends JFrame {

    //private JFrame mainFrame;
    private JLabel headerLabel;
    private JLabel statusLabel;
    private JPanel controlPanel;

    public UserDetails() {
        prepareGUI();
    }


    private void prepareGUI() {
        //mainFrame = new JFrame("Java Swing Examples");
        setSize(800, 800);
        setLayout(new GridLayout(3, 5));
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent windowEvent) {
                System.exit(0);
            }
        });
        headerLabel = new JLabel("This is Header", JLabel.CENTER);
        statusLabel = new JLabel("This is Status", JLabel.CENTER);

        statusLabel.setSize(350, 100);

        controlPanel = new JPanel();
        controlPanel.setLayout(new FlowLayout());

        System.out.println(controlPanel);
        add(headerLabel);
        add(controlPanel);
        add(statusLabel);
        //setVisible(true);
    }

    public void showDetails() {

        // Here I want display the welcome message and also to add all the registered user details.
    }
}

Please help me how to create an application that contains multiple pages?
