**当前只有添加、查询，没有删除和修改部分：**

import java.util.LinkedList;

        }
    
        @Override

            return "Goods{" +
                    "id='" + id + '\'' +

            Shelf shelf2 = new Shelf("001");
            shelf2.GoodsAdd(new Goods("2001", "ccc", 33));
            shelf2.GoodsAdd(new Goods("2002", "ddd", 44));
    
            warehouse.ShelfAdd(shelf);
