本文实例为大家分享了java实现2048游戏源代码，供大家参考，具体内容如下
一.主要功能：
1、游戏初始化：新建游戏4×4的16宫格画布，随机格子上生成2或者4两个数字
2、格子的移动：先判断能否移动，移动后判断能否合并，合并后改变格子颜色和数字
3、新格子的生成：移动一次，就在剩余的空格子中随机生成一个2或者4
4、判赢：16宫格中合并出了“2048”则为游戏胜利
5、判输：16宫格中没有剩余空格子且不能再向任何方向移动则为游戏失败
二.项目的主要结构：
在项目2018游戏中，有4个源文件，此外，还有3个.png和两个.wav格式的音乐文件。一个音乐是按键移动的声音，另外一个是碰撞后的消除的声音。然后游戏的最高分保存是在Recording源文件中，之后附上所需的图片文件和音乐文件：
来了来了.
