【Java案例】公司员工工资发放

约定不等于承诺〃 2024-03-29 15:48 61阅读 0赞

**案例介绍：**

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。

②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。

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，并打印某个月的工资。

（2）每个类都完全封装，不允许有非私有化属性。

**运行结果：**
