使用JPopupMenu从JMenuItem获取JMenu

import javax.swing.*;

public class PopupMenuExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Popup Menu Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(300, 200);

        JPopupMenu popupMenu = new JPopupMenu();
        JMenuItem menuItem = new JMenuItem("Menu Item");
        popupMenu.add(menuItem);

        JMenu menu = (JMenu) menuItem.getParent().getInvoker();
        System.out.println("JMenu: " + menu.getText());

        frame.addMouseListener(new MouseAdapter() {
            @Override
            public void mousePressed(MouseEvent e) {
                if (e.isPopupTrigger()) {
                    popupMenu.show(e.getComponent(), e.getX(), e.getY());
                }
            }

            @Override
            public void mouseReleased(MouseEvent e) {
                if (e.isPopupTrigger()) {
                    popupMenu.show(e.getComponent(), e.getX(), e.getY());
                }
            }
        });

        frame.setVisible(true);
    }
}
