将上述问题转化为Java代码

好的，以下是一个基于上述框架的 Java 代码示例：

import java.awt.BorderLayout;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.Timer;

public class MyGame extends JFrame implements ActionListener {
    private static final long serialVersionUID = 1L;
    private JLabel label;
    private JTextField textField;
    private JButton startButton;
    private int score = 0;
    private Timer timer;
    private Random random;
    private String[] characters = {"汉", "字", "打", "游", "戏"};
    
    public MyGame() {
        super("学号姓名-实验8");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        // 创建 GUI 界面
        label = new JLabel();
        label.setFont(new Font("宋体", Font.PLAIN, 40));
        textField = new JTextField(10);
        startButton = new JButton("开始游戏");
        startButton.addActionListener(this);
        JPanel panel = new JPanel();
        panel.add(label);
        panel.add(textField);
        panel.add(startButton);
        getContentPane().add(panel, BorderLayout.CENTER);
        
        // 初始化定时器和随机数生成器
        timer = new Timer(5000, this);
        random = new Random();
        
        // 显示窗口
        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    }
    
    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == startButton) {
            // 开始游戏
            score = 0;
            startButton.setEnabled(false);
            textField.setEnabled(true);
            textField.setText("");
            label.setText("");
            timer.start();
        } else if (e.getSource() == timer) {
            // 定时器触发
            int index = random.nextInt(characters.length);
            label.setText(characters[index]);
        } else if (e.getSource() == textField) {
            // 玩家输入事件
            String input = textField.getText().trim();
            String current = label.getText();
            if (input.equals(current)) {
                score++;
                int index = random.nextInt(characters.length);
                label.setText(characters[index]);
                textField.setText("");
            }
        }
    }
    
    public static void main(String[] args) {
        new MyGame();
    }
}

注意，您需要根据自己的实际需求对代码进行修改和完善，例如添加计时器、存储分数等功能。
