public class ColaEmployee {
     String name;
        int month;
        public ColaEmployee(){
            
        }
        public ColaEmployee(String name,int month){
            this.name = name;
            this.month = month;
        }
        public double getSalary(int month){
            return 0;
        }
    } 

(2) SalariedEmployee ：     ColaEmployee 的子类，拿固定工资的员工。属性：月薪

public class SalariedEmployee extends ColaEmployee {
     double monSalary;
        public SalariedEmployee(String name,int month,double monSalary){
            super(name,month);
            this.monSalary = monSalary;
        }
        public double getSalary(int month){
            if(super.month==month){
                return monSalary+100;
            }else{
                return monSalary;
            }
        }
         
}

(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

public class HourlyEmployee extends ColaEmployee {
     private int hourSalary;
        private int hourNum;
        public HourlyEmployee(String name,int month,int hourSalary,int hourNum){
            super(name,month);
            this.hourSalary = hourSalary;
            this.hourNum = hourNum;
        }
        public double getSalary(int month){
        if(super.month==month){
            if(hourNum>160){
                return hourSalary*160+hourSalary*(hourNum-160)*1.5+100;
            }else{
                return hourSalary*hourNum+100;
            }
        }else{
            if(hourNum>160){
                return hourSalary*160+hourSalary*(hourNum-160)*1.5;
            }else{
                return hourSalary*hourNum;
            }
        }
        }

}

(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

public class SalesEmployee extends ColaEmployee {
     private int monthSales;
        private double royatyRate;
        public SalesEmployee(String name,int month,int monthSales,double royaltyRate){
            super(name,month);
            this.monthSales = monthSales;
            this.royatyRate = royaltyRate;
        }
        public double getSalary(int month){
            if(super.month==month){
                return monthSales*royatyRate+100;

                return monthSales*royatyRate;
            }
        }

}

(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。

public class Company {
     public void getSalary(ColaEmployee a,int month){
            System.out.println(a.name+"在"+month+"月的月薪为"+a.getSalary(month)+"元");
        }
}

public class TestCompany {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ColaEmployee[] ae1={
                new SalariedEmployee("SalariedEmployee",5,8000),
                new HourlyEmployee("hourlyEmplotee",5,60,250),
                new SalesEmployee("salesEmployee",4,60000,0.4)
        };
        for(int i=0;i<ae1.length;i++){
            new Company().getSalary(ae1[i],5);
        }
    }

}
