这么长的代码 没有耐心看

[dyf20081124]

报什么样的错给贴一下。。

[浊丶ge]

大哥直接说问题啊。。。。这怎么看？？？？

[LinY_X]

贴报错代码

[ThisTimed]

又不贴错误，标题还大二学生，楼主是来秀优越感的吧

[ilovefzq]

贴的代码也不全，让人力不从心啊

[可乐罐]

没错误信息，一堆纯净的代码。。。。。

[上帝的无名指]

大二，你能写出来？ 不然早就把问题说清楚了， 敢说不是copy的

[猿猿猿媛]

[绝对在乎妮]

这是在窗口拖来拖去生的东西

[IT_NK]

哎嘛！学习哈大学生的代码！

[朗晴]

楼主是老师么

[机器学习之禅]

代码没注释，没日志输出，没有单元测试，不说错在哪 ，这帖子可以删了
