Add类 

Employee_Test类

 四、运行结果

---

一、实验目的

1、了解和掌握类的构造方法，继承方法的相关知识。

2、能够使用类的继承及其应用解决实际应用问题，如设计一个雇员类，并实现雇员对象基本信息的管理。

二、雇员类设计实验的内容及步骤

实现一个名为Person的类和它的子类Employee，Manager是Employee的子类，

（1）Person类中的属性有：姓名（name，String），地址（address，String），定义该类的构造方法。

（2）Employee类中的属性有：工号（ID，String），工资（wage，double），工龄（workingyears，int），级别（level，String），定义该类的构造方法；

（3）Manager类中的属性有：部门（department，String），定义该类的构造方法；

（4）要求使用方法的重写（人，员工，经理类信息的输出方法）；要求实现类的构造方法（super关键字）

（5）编写一个测试类，产生一个员工和一个经理对象，输出员工和经理的基本信息；

（6）设计一个Add类用于涨工资，普通员工一次能涨10%，经理能涨20%。

（7）员工工龄超过3年的涨一次工资，部门经理工龄超过1年的涨一次工资。
