JAVA第二次作业
啊 题目真的不难 但是
总是习惯性的字符比较久== 在JAVA里这可是比较的引用啊啊找了半天的bug就是这个 哭哭
代码有空再贴 先去踢球
Update 2018-8-16 00:11:08
更新代码
题目不难但是写起来是真的累，父类抽象类为person
继承的两个子类是Student和Teacher
类里面写方法设置对象的成员变量的值，剩下的就是输入输出格式了。统计部分很简单就是遍历一遍得到最大值，然后输出所有最大值是times的数据

代码很丑因为很多地方都是找bug时候随意写的，但是基本bug都是字符串比较的问题，另外今天OJ突然不能查分了搞的群里都喷起来了，目前是每道题只能提交5次，包括之前超过5次的题目现在剩余次数就是负数，感觉这届助教不太行，唉。
