第15次Java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。

package zuoye;

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

package zuoye;

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

  private double hours;
    private int mon;
    public HourlyEmployee(String name, int months, int birthday,double hours,int mon) {
        super(name, months, birthday);
        this.hours=hours;
        this.mon=mon;
        if(super.getBirthday()!=super.getMonths()&&super.getMonths()>=160) {
            System.out.println("员工"+name+months+"月的工资为"+(mon*160+(hours-160)*mon*1.5));
        }else  if(super.getBirthday()==super.getMonths()&&super.getMonths()>=160){
            System.out.println("员工"+name+months+"月的工资为"+(mon*160+(hours-160)*mon*1.5+100));
        }else if(super.getBirthday()==super.getMonths()&&super.getMonths()<160) {
            System.out.println("员工"+name+months+"月的工资为"+(mon*hours+100));
        }else if(super.getBirthday()!=super.getMonths()&&super.getMonths()<160) {
            System.out.println("员工"+name+months+"月的工资为"+mon*hours);
        }

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

package zuoye;

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;
    }
    public double getSalary(int month) {
        if (super.month == month)
        {
            return monthSales * royaltyRate + 100;
        } else {
            return monthSales * royaltyRate;
        }
    }
 
}

(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。

package zuoye;

public class TestCompany {
    public static void main(String[] args) {
       
        ColaEmployee[] all = {
                new SalariedEmployee("asd", 5, 30000),
                new HourlyEmployee("qwe", 4, 100, 300),
                new SalesEmployee("zxc", 3, 7000000, 0.3)
                };
       
        for (int i = 0; i < all.length; i++) {
            new Company().getSalary(all[i],5);
        }
    }
}
