    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);
            }
        }
    }
