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
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在一个 ColaEmployee 数组里，并单元出数组中每个员工当月的工资。
资的员工。属性：月薪
