Java打汉字游戏的具体实例

以下是一个简单的Java打汉字游戏的代码示例：

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.util.Random;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class HanziGame extends JPanel implements KeyListener {
    private static final long serialVersionUID = 1L;

    private static final int WIDTH = 600;
    private static final int HEIGHT = 400;
    private static final int FONT_SIZE = 30;
    private static final int MAX_SPEED = 10;
    private static final int MAX_SCORE = 10;

    private char hanzi;
    private int x, y;
    private int speed;
    private int score;
    private boolean gameOver;

    public HanziGame() {
        setPreferredSize(new java.awt.Dimension(WIDTH, HEIGHT));
        setFocusable(true);
        requestFocusInWindow();
        addKeyListener(this);
        init();
    }

    private void init() {
        Random rand = new Random();
        hanzi = (char) (rand.nextInt(20902) + 19968);
        x = rand.nextInt(WIDTH - FONT_SIZE);
        y = -FONT_SIZE;
        speed = rand.nextInt(MAX_SPEED) + 1;
        score = 0;
        gameOver = false;
    }

    @Override
    public void keyPressed(KeyEvent e) {
        if (!gameOver) {
            char ch = e.getKeyChar();
            if (ch == hanzi) {
                score++;
                if (score >= MAX_SCORE) {
                    gameOver = true;
                } else {
                    init();
                }
            }
        }
    }

    @Override
    public void paint(Graphics g) {
        super.paint(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setPaint(Color.black);
        g2d.fillRect(0, 0, WIDTH, HEIGHT);
        g2d.setPaint(Color.white);
        g2d.setFont(new Font("宋体", Font.BOLD, FONT_SIZE));
        g2d.drawString(String.valueOf(hanzi), x, y);
        g2d.drawString("得分：" + score, 20, 30);
        if (gameOver) {
            g2d.drawString("游戏结束！", 250, 200);
        }
    }

    @Override
    public void keyReleased(KeyEvent e) {}

    @Override
    public void keyTyped(KeyEvent e) {}

    public void move() {
        y += speed;
        if (y >= HEIGHT) {
            gameOver = true;
        }
    }

    public static void main(String[] args) throws InterruptedException {
        JFrame frame = new JFrame("Java打汉字游戏");
        HanziGame game = new HanziGame();
        frame.add(game);
        frame.pack();
        frame.setResizable(false);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);

        while (true) {
            game.move();
            game.repaint();
            Thread.sleep(30);
        }
    }
}

这个游戏的主要逻辑是：

1. 随机生成一个汉字和它的位置和速度；

2. 在屏幕上绘制汉字和得分；

3. 当用户输入正确的汉字时，加分并随机生成下一个汉字；

4. 当用户得分达到一定分数或者汉字超出屏幕时，游戏结束。

上面的代码实现了一个简单的打汉字游戏，可以根据需要进行修改和优化。
