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。

 (1)

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)

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)

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)

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)

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 TestCompany {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ColaEmployee[] cel = {
                new SalariedEmployee("salariedEmployee", 6, 30000),//name,month,月薪
                new HourlyEmployee("hourlyEmployee", 5, 100, 300),//name,month,时薪,小时数
                new SalesEmployee("salesEmployee", 3, 7000000, 0.3)//name,month,月销售额,提成率
                };
        for (int i = 0; i < cel.length; i++) {
            new ompany().getSalary(cel[i],7);
        }
	}

}
