5-20作业

4、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。

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

  • 属性:月薪

(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) 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

(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,写一个测试类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 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;
    }

}
public class SalariedEmployee extends ColaEmployee{
    double monSalary;//月薪

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

    }

}
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;
            }
        }

    }

}
public class SalesEmployee extends ColaEmployee{
    private int monthSales;
    private double royaltyRate;

    public SalesEmployee(String name, int month,int monthSales,double royaltyRate) {
        super(name, month);
        this.monthSales = monthSales;
        this.royaltyRate = royaltyRate;
    }
    //    工资=月销售额*提成率
    public double getSalary(int month) {
        if(super.month == month) {
            return monthSales * royaltyRate + 100;
        }else {
            return monthSales * royaltyRate;
        }
    }

}
public class Company {
    public void getSalary(ColaEmployee c,int month) {
        System.out.println(c.name + "在" + month + "月的月薪为" + c.getSalary(month)+"元");
    }
}
public class Textcompany {
    public static void main(String[] args) {
        ColaEmployee[] cel = {
                new SalariedEmployee("salariedEmployee", 6, 30000),
                new HourlyEmployee("hourlyEmployee", 5, 100, 300),
                new SalesEmployee("salesEmployee", 3, 7000000, 0.3)
        };
        for (int i = 0; i < cel.length; i++) {
            new Company().getSalary(cel[i],7);
        }
    }
}
