4、 Cola公司的雇员分为以下若干类：(知识点：多态) [必做 题] 

4.1 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。

4.2 SalariedEmployee ： ColaEmployee 的子类，拿固定工 资的员工。属性：月薪 课后作业 

4.3 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

4.4 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 

4.5 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。
