建立工资计算系统（2）

问题描述

某企业为了提升自身管理效率，特别委托你为企业设计一个自动计算和发放员工工资的软件，具体设计内容包括：
1、随着该企业规模的扩展，企业的员工类型逐渐多样化，工资系统的管理方式要随之发生改变。企业目前的员工主要分为三类，第一类为生产线员工，每工作一天企业记工资500元；第二类为销售员工，每工作一天企业记工资400元，但是每销售一件产品提成50元；第三类为顾问类员工，工资按咨询次数记，每次300元。
2、请在工资系统（1）的基础上分别为这三类员工设计与之对应的员工类，他们共同继承超类Employee，超类表示一个企业员工的基本信息，并定义所有员工类都必须具有的接口，比如个人信息显示、属性设置和读取、工资计算和发放等。
3、在每个派生员工类中设计与员工类型对应的工资计算方法，同时根据每种员工工资计算需要的属性的不同，对每个子类进行扩展，为每个子类设计个人信息和工资信息的输出方法；
4、上面类所有成员变量使用private修饰，为这些属性编写设置和读取方法，同时在设置方法中还需要对每个属性值的设置范围进行检查，如果超出取值范围，请为该值设置初始值并提示用户。
5、编写一个测试方法，每种员工类型实例化两个对象，并采用适当的属性值进行初始化，对每个员工的工资进行计算并输出该员工相关信息。计算需要支付给这两个员工的工资。
