package com.example;

/**
1.利用学号和姓名处理基本信息：
（1）输出：姓名，校名，专业，年级（学号中第10位为专业位，1表示语文，2表示数学，3表示英语）。
格式为：姓名：小明，A大学数学专业 2016级学生
（2）输出Email地址
格式为：姓名：小明 Email地址是：111111111311@mail.com
2.以1为父类定义子类实现成绩管理
利用语文、数学、英语成绩计算并输出
计算并输出语文、数学、英语三门课的成绩总分，最高分，最低分
输出格式为：学号：姓名：总分：最高分：最低分：
3.在main方法中使用实际的数据调用以上的功能
（生成一个对象是自己的姓名和学号）
