    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);
            }
    	}
    
    }
