本文实例为大家分享了Java实现简单版贪吃蛇游戏的具体代码，供大家参考，具体内容如下
这是一个比较简洁的小游戏，主要有三个类，一个主类，一个食物类，一个贪吃蛇类。
1、首先定义主类，主类中主要用来创建窗口

public class Main { public static final int WIDTH=600; public static final int HEIGHT=600; public static void main(String[] args) { JFrame win =new JFrame(); win.setVisible(true); win.setSize(WIDTH, HEIGHT); win.setDefaultCloseOperation(3); win.setLocationRelativeTo(null); SnakePanel panle =new SnakePanel(); win.add(panle); SnakePanel.Key l = panle.new Key(); win.addKeyListener(l); panle.addKeyListener(l); panle.run(); }} |
2、其次是定义食物类，食物有长和宽，还有在窗口中的位置

import java.util.Random;public class Cell { protected int x; protected int y; protected int width; protected int height; Random ran=new Random(); public Cell(){ Random ran=new Random(); this.x=ran.nextInt(25)*15+60; this.y=ran.nextInt(25)*15+50; this.width=15; this.height=15; } public Cell(int x,int y){ this(); this.x=x; this.y=y; } public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } public int getWidth() { return width; } public void setWidth(int width) { this.width = width; } public int getHeight() { return height; } public void setHeight(int height) { this.height = height; }} |
3、最后是蛇类

至此，一个简单的贪吃蛇小游戏就完成了。
