Question

求java小程序源代码 在线等 急急急！！！

那个高手给个Java小程序的源代码

大约2000行左右就行

要有开发文档
最好是小游戏 之类的程序

Answer 1

下面是俄罗斯方块游戏源代码
还没完，这代码太长了，我用我另一个号再粘上

Answer 3

/*
*12.24日,完成了蛇撞到自己的检测.修改方法是在蛇的初始化的时候,用双循环来置FALSE;
* 在重写代码的时候,我借鉴了别人的思路:将整个游戏的界面定义为一个布尔型的二维数组.
* 用一个LinkedList来储存蛇.当蛇移动的时候,在蛇的头部增加一个节点,然后删除最后一个节点.
* 因为只是做练习,所以没做游戏界面,比如菜单栏,计分栏什么的.另外还有一个问题，就是当两次点击回车时，蛇的移动速度会变快
