需要有关如何将实例数组传递给另一个数组的建议

Question

首先，我仍在学习过程中，感谢我在这里获得的所有帮助。我正在创建一个客户可以排队多个三明治订单的程序。现在该程序非常基本，但适用于下一个订单。一旦一切都启动并运行，我将用更多的项目填写它。我想将我的子数组传递给一个订单数组来保存多个三明治，然后一旦整个订单完成，我就会打印出一个总计。我也不确定我将如何循环程序以放置多个订单，但我觉得这应该在订单类中完成，除非有一种更简单的方法可以在主程序中完成所有操作。任何建议或指针表示赞赏。我会在继续努力的过程中更新。

这里只是两个数组类

class Order
{
    private static List<Items> order = new List<Order>(15);

    public Order() {}
}

class Sandwich
{
    private static ArrayList<Ingredients> ingredients = new ArrayList<Ingredients>(20);

    public Sandwich() {}

    public static void addIngredients(Ingredients x) { ingredients.add(x); }


    public String toString()
    {
        String yourOrder = "\n Your order is as follows: \n ";
        for (int i = 0; i < ingredients.size(); i++)
        {
            if (ingredients.get(i) instanceof Bread)
                 { yourOrder += "\nBread type: " + ingredients.get(i); }
            if (ingredients.get(i) instanceof Meat)
                { yourOrder += "\nMeat type: " + ingredients.get(i); }
            if (ingredients.get(i) instanceof Cheese)
                { yourOrder += "\nCheese type: " + ingredients.get(i); }
            if (ingredients.get(i) instanceof Veggies)
                { yourOrder += "\nVeggie type: " + ingredients.get(i); }

    }

    return yourOrder;
   }
}

我什至不确定这是否是为订单类声明数组的最佳方式。但我想将三明治数组存储在订单类中，以便以后打印出来并加起来价格等等。

Answer 1

您应该创建一个名为 Orders 或 OrdersList 的新类。 OrdersList 类将包含多个 Order 类。
