如何设置一个JFrame按钮来打开另一个JFrame，然后在第二个jframe关闭后接收信息？

import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class MainFrame extends JFrame {
    private JButton openButton;

    public MainFrame() {
        setTitle("Main Frame");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        openButton = new JButton("Open Second Frame");
        openButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                SecondFrame secondFrame = new SecondFrame();
                secondFrame.setVisible(true);
            }
        });

        getContentPane().add(openButton);
        pack();
        setLocationRelativeTo(null);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                MainFrame mainFrame = new MainFrame();
                mainFrame.setVisible(true);
            }
        });
    }
}

import javax.swing.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

public class SecondFrame extends JFrame {
    private JLabel messageLabel;

    public SecondFrame() {
        setTitle("Second Frame");
        setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

        messageLabel = new JLabel("This is the second frame.");
        getContentPane().add(messageLabel);
        pack();
        setLocationRelativeTo(null);

        // 监听窗口关闭事件
        addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosed(WindowEvent e) {
                // 向MainFrame发送信息
                MainFrame.receiveMessage("Message from Second Frame");
            }
        });
    }
}

public class MainFrame extends JFrame {
    // ...

    // 接收来自SecondFrame的信息
    public static void receiveMessage(String message) {
        System.out.println("Received message: " + message);
    }
    
    // ...
}
