Sure! Here's the commented version of your code:

package total.gui;

import javax.swing.*;
import javax.swing.filechooser.FileNameExtensionFilter;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import total.date.Animal;

import total.view.GamePanel;

public class AppWindow extends JFrame implements ActionListener { // 继承JFrame类，实现ActionListener接口
    GamePanel gamePanel; // 游戏面板对象
    JTextField text; // 文本框对象

    public AppWindow() {
        setTitle("动物换位游戏"); // 界面命名为“动物换位游戏”
        gamePanel = new GamePanel(); // 实例化游戏面板对象
        gamePanel.setAnimalCount(6); // 设置动物数量
        gamePanel.setLeftAnimalImage("C:\\Users\\杨凯栋\\Desktop\\Animal_game\\Animal_game\\image\\cat.jpg"); // 设置左边动物图像路径
        gamePanel.setRightAnimalImage("C:\\Users\\杨凯栋\\Desktop\\Animal_game\\Animal_game\\image\\dog.jpg"); // 设置右边动物图像路径
        add(gamePanel, BorderLayout.CENTER); // 将游戏面板添加到窗口中央位置
        gamePanel.setBackground(Color.pink); // 设置游戏面板背景颜色为粉色
        JPanel northP = new JPanel(); // 创建一个面板用于放置按钮和文本框
        northP.add(gamePanel.buttonReStart); // 将重新开始按钮添加到面板上
        northP.add(gamePanel.buttonRedo); // 将重做按钮添加到面板上
        add(northP, BorderLayout.NORTH); // 将面板添加到窗口北部位置
        setBounds(60, 60, 9 * gamePanel.width + 9 * gamePanel.gap, 300); // 设置窗口大小和位置
        text = new JTextField(10); // 创建一个文本框对象
        northP.add(text); // 将文本框添加到面板上
        validate(); // 验证容器及其子组件
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // 设置窗口关闭时退出程序
        setVisible(true); // 设置窗口可见
    }

    public void actionPerformed(ActionEvent e) {
        Component container = null; 
        JOptionPane.showMessageDialog(container, JOptionPane.INFORMATION_MESSAGE); // 弹出一个消息对话框显示信息
    }

    public static void main(String args[]) {
        AppWindow win = new AppWindow(); // 创建一个AppWindow对象
    }
}
