JDBC 员工工资管理系统 请各位解答

重构工资计算方法

问题遇到的现象和发生背景

员工工资管理系统
Employee：这是所有员工总的父类，属性：员工编号、姓名、出生日期。方法：getSalary(int month)根据参数月份来计算某月工资，如果该月员工过生日，则公司会额外奖励200元。
SalesEmployee：Employee的子类，销售人员，工资由底薪和月销售额和提成率决定。属性：底薪，月销售额，提成率。
ManagerEmployee：Employee的子类，管理人员，工资由基础工资、岗位工资和绩效工资决定。属性：基础工资，岗位工资，绩效系数。绩效基数是所有销售人员销售提成平均值的60%。
OfficeEmployee：Employee的子类，内勤员工，工资由基础工资、岗位工资决定。属性：基础工资，岗位工资。

我的解答思路和尝试过的方法

//绩效工资=绩效基数绩效系数
//绩效基数=所以销售人员的销售提成的平均值60%
//销售提成=月销售额*提成率

我想要达到的结果

为 ManagerEmployee重构方法 计算出工资

因为不知道怎么把总销售提成传入进去，所以我在ManagerEmployee类增加了一个字段salarys用于存储总销售提成，然后把此月生日判断稍微修改了一下，增加了OfficeEmployee内勤员工类的实现，给每个类增加toString()方法用于打印对象的信息，修改如下：

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
 
/**

 * 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。
