以下是一份简单的 Java 代码实现贪吃蛇游戏的示例：

\`\`\` import java.awt.Color; import java.awt.Dimension; import java.awt.Graphics; import java.awt.Point; import java.awt.Toolkit; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyEvent; import java.awt.event.KeyListener; import java.util.ArrayList; import java.util.Random;

import javax.swing.JFrame; import javax.swing.Timer;

public class SnakeGame implements ActionListener, KeyListener \{

public static SnakeGame snake;

public JFrame jframe;

public RenderPanel renderPanel;

public Timer timer = new Timer(20, this);

public ArrayList snakeParts = new ArrayList ();

public static final int UP = 0, DOWN = 1, LEFT = 2, RIGHT = 3, SCALE = 10;

public int ticks = 0, direction = DOWN, score, tailLength = 10, time;

public Point head, cherry;

public Random random;

public boolean over = false, paused;

public Dimension dim;

public SnakeGame() \{ dim = Toolkit.getDefaultToolkit().getScreenSize(); jframe = new JFrame("Snake Game"); jframe.setVisible(true); jframe.setSize(805, 700); jframe.setResizable(false); jframe.setLocation(dim.width / 2 - jframe.getWidth() / 2, dim.height / 2 - jframe.getHeight() / 2); jframe.add(renderPanel = new RenderPanel()); jframe.setDefaultCloseOperation(JFrame.EXIT\_ON\_CLOSE); jframe.addKeyListener(this); startGame(); \}

public void startGame() \{ over = false; paused = false; time = 0; score = 0; tailLength = 14; direction = DOWN; head = new Point(0, -1); random = new Random(); snakeParts.clear(); cherry = new Point(random.nextInt(79), random.nextInt(66)); timer.start(); \}

@Override public void actionPerformed(ActionEvent e) \{ renderPanel.repaint(); ticks++; if (ticks % 2 == 0 && head != null && !over && !paused) \{ time++; snakeParts.add(new Point(head.x, head.y)); if (snakeParts.size() > tailLength) \{ snakeParts.remove(0); \} if (direction == UP) \{ if (head.y - 1 >= 0 && noTailAt(head.x, head.y - 1)) \{ head = new
