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。

package huada;

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 huada;

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("名字"+name+months+"工资为"+(mon*160+(hours-160)*mon*1.5));
        }else  if(super.getBirthday()==super.getMonths()&&super.getMonths()>=160){
            System.out.println("名字"+name+months+"工资为"+(mon*160+(hours-160)*mon*1.5+100));
        }else if(super.getBirthday()==super.getMonths()&&super.getMonths()<160) {
            System.out.println("名字"+name+months+"的资为"+(mon*hours+100));
        }else if(super.getBirthday()!=super.getMonths()&&super.getMonths()<160) {
            System.out.println("名字"+name+months+"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 huada;
   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 huada;
  
  public class Company {
      public void getsalary(ColaEmployee c, int month) {
          System.out.println(c.name  + c.month + "的工资为" + c.getSalary(month));
      }
  
      public static void main(String[] args) {
          ColaEmployee[] c = { new SalariedEmployee("月薪员工", 6, 3500), new HourlyEmployee("时薪员工", 8, 16, 360),
                 new SalesEmployee("销售员工", 9, 188, 30), };
         for (int i = 0; i < c.length; i++) {
             new Company().getsalary(c[i], 5);
         }
  }
 }
