Java撸出来的贪吃蛇作业
之前看见有人发了个C语言的贪吃蛇，想起我在大一下Java老师给我们留的大作业就是贪吃蛇，{:1_918:}所以发出来给大家分享交流一下。老师要求是有障碍物，能换皮肤，能够暂停，这可把我们一群非计算机的学生难倒了{:1_924:}。
本人是在校电子专业的本科生，这个贪吃蛇也算是被逼着写出来的，{:1_936:}有什么缺陷还望指正。

游戏运行如下，很丑:(eew，望见谅。
还有一种皮肤是走一步变一下的。。。
总的来说，老师还是让我们过关了，也算是没白费了。。。
感谢大家！！！ goupiluobo 发表于 2018-4-3 19:37
花了多少时间？
当时因为同时在学高数，电路与概率论。而且算是一边学一边做，用了蛮长的时间的。 谢谢，也在学习java 谢谢分享 感谢分享 花了多少时间？ 不错啊，还是可以的，那天我也写个牛逼一点的超过你，哈哈 哈哈可以，
虽然效果一般,但是代码写的好6啊,{:1_921:}
