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
。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- -个方法,调用该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。
