            sheepList.remove(i);

//      sheepList.remove(2);

        for(int i = 0;i < sheepList.size();i ++){       
            System.out.println(((Sheep)(sheepList.get(i))).name);
        }

//方法二
 for(int i=0;i<sheeps.size();i++){ System.out.println(sheeps.get(i));

          } System.out.println("删除后三个");

         for(int i=0;i<sheeps.size()-3;i++){
          System.out.println(sheeps.get(i));

          } System.out.println("删除前两个"); 
             for(int  i=sheeps.size()-1;i>sheeps.size()-4;i--){
          System.out.println(sheeps.get(i));

          }


    }
