帮我用Java写一个贪吃蛇‘

好的，我可以为您提供一个简单的贪吃蛇游戏的Java代码，如下所示：

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class SnakeGame extends JFrame implements ActionListener {
    private static final long serialVersionUID = 1L;
    private JPanel gamePanel;
    private JLabel statusLabel;
    private Timer timer;
    private int delay = 100;
    private int score = 0;
    private int snakeX[] = new int[1000];
    private int snakeY[] = new int[1000];
    private int snakeLength = 3;
    private int foodX, foodY;
    private int direction = 0;
    private boolean gameOver = false;

    public SnakeGame() {
        setTitle("贪吃蛇");
        setSize(400, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);

        gamePanel = new JPanel();
        gamePanel.setBackground(Color.WHITE);
        gamePanel.setLayout(null);
        add(gamePanel);

        statusLabel = new JLabel("得分: 0");
        statusLabel.setBounds(10, 10, 100, 20);
        gamePanel.add(statusLabel);

        timer = new Timer(delay, this);
        timer.start();

        addKeyListener(new KeyAdapter() {
            public void keyPressed(KeyEvent e) {
                int key = e.getKeyCode();
                if (key == KeyEvent.VK_LEFT && direction != 1) {
                    direction = 0;
                } else if (key == KeyEvent.VK_RIGHT && direction != 0) {
                    direction = 1;
                } else if (key == KeyEvent.VK_UP && direction != 3) {
                    direction = 2;
                } else if (key == KeyEvent.VK_DOWN && direction != 2) {
                    direction = 3;
                }
            }
        });

        initGame();
    }

    private void initGame() {
        snakeLength = 3;
        snakeX[0] = 50;
        snakeY[0] = 50;
        snakeX[1] = 40;
        snakeY[1] = 50;
        snakeX[2] = 30;
        snakeY[2] = 50;
        direction = 1;
        score = 0;
        statusLabel.setText("得分: " + score);
        generateFood();
        gameOver = false;
    }

    private void generateFood() {
        foodX = (int) (Math.random() * 38) * 10;
        foodY = (int) (Math.random() * 38) * 10;
    }

    private void move() {
        for (int i = snakeLength - 1; i > 0; i--) {
            snakeX[i] = snakeX[i - 1];
            snakeY[i] = snakeY[i - 1];
        }
        if (direction == 0) {
            snakeX[0] -= 10;
        } else if (direction == 1) {
            snakeX[0] += 10;
        } else if (direction == 2) {
            snakeY[0] -= 10;
        } else if (direction == 3) {
            snakeY[0] += 10;
        }
        if (snakeX[0] < 0 || snakeX[0] > 380 || snakeY[0] < 0 || snakeY[0] > 380) {
            gameOver = true;
        }
        for (int i = 1; i < snakeLength; i++) {
            if (snakeX[0] == snakeX[i] && snakeY[0] == snakeY[i]) {
                gameOver = true;
            }
        }
        if (snakeX[0] == foodX && snakeY[0] == foodY) {
            snakeLength++;
            score += 10;
            statusLabel.setText("得分: " + score);
            generateFood();
        }
    }

    public void paint(Graphics g) {
        super.paint(g);
        if (!gameOver) {
            g.setColor(Color.RED);
            g.fillRect(foodX, foodY, 10, 10);
            g.setColor(Color.BLACK);
            for (int i = 0; i < snakeLength; i++) {
                g.fillRect(snakeX[i], snakeY[i], 10, 10);
            }
        } else {
            g.setColor(Color.BLACK);
            g.drawString("游戏结束", 180, 180);
        }
    }

    public void actionPerformed(ActionEvent e) {
        if (!gameOver) {
            move();
            repaint();
        } else {
            timer.stop();
        }
    }

    public static void main(String[] args) {
        new SnakeGame().setVisible(true);
    }
}

希望这个代码对您有所帮助！
