Java |如何在“永远”循环运行时关闭JFrame？

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

public class MainFrame extends JFrame {
    private boolean isRunning;

    public MainFrame() {
        isRunning = true;
        setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                isRunning = false;
                dispose();
            }
        });
        // 添加其他组件和设置
        // ...
    }

    public void run() {
        while (isRunning) {
            // 循环运行的代码
            // ...
        }
    }

    public static void main(String[] args) {
        MainFrame frame = new MainFrame();
        frame.setSize(800, 600);
        frame.setVisible(true);
        frame.run();
    }
}
