第十一周课后作业

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。
