emmm......就当练习了系列19
选课系统项目中涉及到诸多数据与功能，要求引入面向对象的思想对其进行高度整合
1、学校数据与功能整合
2、课程数据与功能进行整合
3、学生数据与功能进行整合
4、讲师数据与功能进行整合
5、班级数据与功能进行整合
ps：不会写的同学，可以先用普通的方式，先把数据与功能都给写好，再考虑基于面向对象的思想进行整合
数据部分：
校区的名字：如"老男孩上海校区"
校区的地址：如"上海虹桥"
班级名字
班级所在校区
学生的学校
学生的姓名
学生的年龄
学号
学生的性别
课程名字
课程周期
课程价格
老师的名字
老师的年龄
老师的薪资
老师的等级
功能部分：
校区创建完毕后，可以为每个校区创建班级
班级创建完毕后，可以为每个班级创建课程
学生创建完毕后，学生可以选择班级
老师创建完毕后，可以为学生打分
