考虑到该文件中需要导包等其他操作，请把整个源文件发给我，方便我直接复制

好的，下面是修改后的源文件：

import javax.swing.*;

public class WindowMenu extends JFrame {
    JMenuBar menubar;
    JMenu menuFruit;
    JMenuItem bananaItem, pearItem;
    JMenu menuYoghourt;
    JMenuItem heavyItem, thinnerItem;
    JMenu appleMenu;
    JMenuItem redAppleItem,yellowAppleItem,greenAppleItem;

    public WindowMenu(){}
    public WindowMenu(String s, int x, int y, int w, int h) {
        init(s);
        setLocation(x, y);
        setSize(w, h);
        setVisible(true);
        setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    }

    void init(String s) {
        setTitle(s);
        menubar = new JMenuBar();
        menuFruit = new JMenu("水果菜单");
        bananaItem = new JMenuItem("香蕉");
        setMenuItemIcon(bananaItem, "pic/banana.jpg");
        pearItem = new JMenuItem("甜梨");
        setMenuItemIcon(pearItem, "pic/pear.jpg");
        appleMenu = new JMenu("苹果");
        redAppleItem = new JMenuItem("红苹果");
        setMenuItemIcon(redAppleItem, "pic/redApple.jpg");
        yellowAppleItem = new JMenuItem("黄苹果");
        setMenuItemIcon(yellowAppleItem, "pic/yellowApple.jpg");
        greenAppleItem = new JMenuItem("绿苹果");
        setMenuItemIcon(greenAppleItem, "pic/greenApple.jpg");
        menuYoghourt = new JMenu("酸奶菜单");
        heavyItem = new JMenuItem("厚酸奶");
        setMenuItemIcon(heavyItem, "pic/heavyYoghourt.jpg");
        thinnerItem = new JMenuItem("轻酸奶");
        setMenuItemIcon(thinnerItem, "pic/thinnerYoghourt.jpg");
        menuFruit.add(bananaItem);
        menuFruit.add(pearItem);
        menuFruit.addSeparator();
        menuFruit.add(appleMenu);
        appleMenu.add(redAppleItem);
        appleMenu.add(yellowAppleItem);
        appleMenu.add(greenAppleItem);
        menuYoghourt.add(heavyItem);
        menuYoghourt.add(thinnerItem);
        menubar.add(menuFruit);
        menubar.add(menuYoghourt);
        setJMenuBar(menubar);
    }

    void setMenuItemIcon(JMenuItem item, String iconFileName) {
        item.setIcon(new ImageIcon(iconFileName));
    }
}

注意：在运行该程序时，需要确保`pic`文件夹下的图片文件存在，并且程序能够读取到这些文件。
