• 聚合与组合示例代码

1.  聚合示例代码

   public  class GooseGroup  
   {
       public Goose goose;
       
       public GooseGroup(Goose goose)
       {
           this.goose = goose;
       } 
   }

2.  组合示例代码

   public class Goose  
   {
       public Wing wing;
       
       public Goose()
       {
           wing =new Wing();
       }
   }
