第十一周作业

Cola公司的雇员分为以下若干类：(知识点：多态)

(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。

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;
        }else{
            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 static void main(String[] args) {
        // TODO Auto-generated method stub
        ColaEmployee[] ae1={
                new SalariedEmployee("SalariedEmployee",5,20000),
                new HourlyEmployee("hourlyEmplotee",5,60,300),
                new SalesEmployee("salesEmployee",4,600000,0.4)
        };
        for(int i=0;i<ae1.length;i++){
            new Company().getSalary(ae1[i],8);
        }
    }

}
