某公司的员工分为5类，每类员工都有相应的封装类，这5个类的信息如下
（1)Employee：这是所有员工的父类。
①属性：员工的姓名、员工的生日月份。
)方法：getSalary(int month）根据参数月份确定工资。如果该月员工过生日，则公司会额外发放100元。
（2)SalariedEmployee：Employee 的子类，拿固定工资的员工。
属性：月薪。
（3）HourlyEmployee：Employee的子类，按小时拿工资的员工，每月工作超出160h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：Employee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)BasePlusSalesEmployee：SalesEmployee的子类，有固定底薪的销售人员，工资为
底薪加上销售提成。
属性：底薪。
本题要求根据上述员工分类，编写一个程序，实现以下功能：
（1）创建一个Employee数组，分别创建若干不同的Employee对象，并打印某个月的
（2）每个类都完全封装，不允许有非私有化属性。
