?当前只有添加、查询,没有删除和修改部分:

import java.util.LinkedList;

class Goods
{
    String id;
    String name;
    int price;

    public Goods(String id, String name, int price) {
        this.id = id;
        this.name = name;
        this.price = price;
    }

    @Override
    public String toString() {
        return "Goods{" +
                "id='" + id + '\'' +
                ", name='" + name + '\'' +
                ", price=" + price +
                '}';
    }
}

class Shelf
{
    String id;

    LinkedList<Goods> goodsLinkedList;

    Shelf(String id)
    {
        goodsLinkedList = new LinkedList<>();
        this.id = id;
    }

    public boolean GoodsAdd(Goods goods)
    {
        return goodsLinkedList.add(goods);
    }

    public void GoodsDelete(Goods goods)
    {

    }

    public void GoodsQuery(Goods goods)
    {
        for (Goods temp: goodsLinkedList) {
            System.out.println(temp.toString());
        }
    }

    @Override
    public String toString() {
        return "Shelf{" +
                "id='" + id + '\'' +
                ", goodsLinkedList=" + goodsLinkedList +
                '}';
    }
}
public class Warehouse {
    LinkedList<Shelf> shelfLinkedList;

    Warehouse()
    {
        shelfLinkedList = new LinkedList<>();
    }

    public boolean ShelfAdd(Shelf shelf)
    {
        return shelfLinkedList.add(shelf);
    }

    public boolean ShelfDelete(Shelf shelf)
    {
        return shelfLinkedList.remove(shelf);
    }

    public void ShelfQuery()
    {
        for (Shelf temp: shelfLinkedList) {
            System.out.println(temp.toString());
            temp.GoodsQuery(null);
            System.out.println();
        }
    }

    public static void main(String[] args) {
        Warehouse warehouse = new Warehouse();
        Shelf shelf = new Shelf("001");
        shelf.GoodsAdd(new Goods("1001", "aaa", 11));
        shelf.GoodsAdd(new Goods("1002", "bbb", 22));

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

        warehouse.ShelfAdd(shelf);
        warehouse.ShelfAdd(shelf2);

        warehouse.ShelfAdd(new Shelf("003"));

        warehouse.ShelfQuery();
    }
}
