继承与多态-2

1、(继承与多态)设计Person(人)、Student(学生)、Employee(雇员)、Faculty(教员)、Staff(职员)类，Student、Employee是Person的子类，Faculty、Staff是Employee的子类。所有人都有姓名、地址、电话号码、电子邮件地址。学生有班级状态：大一、大二、大三、大四，将这些状态定义为常量。一个雇员涉及办公室、工资、受聘日期(使用Date类对象)。教员有办公时间、级别。职员有职务称号。覆盖每个类的toString()方法，显示类别名称和姓名。画出这些类的UML图，实现上述要求，用主程序测试这些类并调用他们的toString()。注意：作业提交请将程序和UML放在一个word文档提交
