第九周作业

4、Cola公司的雇员分为以下若干类:(知识点:多态)

(1) ColaEmployee :这是所有员工总的父类,属性:员工的姓名,员工的生日月份。

  • 方法:getSalary(int month) 根据参数月份来确定工资,如果该月员工过生日,则公司会额外奖励100 元。

(2) SalariedEmployee :     ColaEmployee 的子类,拿固定工资的员工。

  • 属性:月薪

(3) HourlyEmployee :ColaEmployee 的子类,按小时拿工资的员工,每月工作超出160 小时的部分按照1.5 倍工资发放。

  • 属性:每小时的工资、每月工作的小时数

(4) SalesEmployee :ColaEmployee 的子类,销售人员,工资由月销售额和提成率决定。

  • 属性:月销售额、提成率

(5) 定义一个类Company,在该类中写一个方法,调用该方法可以打印出某月某个员工的工资数额,写一个测试类TestCompany,在main方法,把若干各种类型的员工放在一个ColaEmployee 数组里,并单元出数组中每个员工当月的工资。
