Java swing框架实现的贪吃蛇游戏完整示例

Java swing框架实现的贪吃蛇游戏完整示例

本文实例讲述了java swing框架实现的贪吃蛇游戏。分享给大家供大家参考，具体如下：

java是门高级语言，做游戏时适合做后台，但是用它也可以做游戏。闲来无事做的时候可以用来写点小游戏，练习练习预防早衰哈哈！

闲话不说了

下面是以前练习的作品，不怕大家笑话，那个时候用了一个礼拜才做出来的。

源码如下供大家学习。

使用的是java的 swing  Jframe Jpanel JButton   当然你也可以使用awt

先来看看运行效果：

具体代码：

package Tcs;
