（一）写一个类，用来存储和操作学生信息。

1. 学生信息包括：学号、姓名、性别、出生日期、院系

2. 需要两种构造器：默认构造器和有参数的构造器

3. 需要各个属性的get和set方法

（二）写一个应用程序，测试这些构造器和方法

参考：仿照附录的Person类和课本P51应用程序例题的写法。-(a) write a class, students used to store and manipulate information.

1. The student information including: student id, name, sex, date of birth, and departments

2. Need two constructors: default constructor and parameter of the constructor

3. Need to get and set methods for each attribute

(2) write an application to test these constructors and methods

Reference: modelled on the appendix of the Person class and textbooks written P51 application examples.
