    Default Error with code

    public class ReOrderList 
    	public static void reOrder(Food qtyInStock, Food reOrderPoint)
    		if(qtyInStock < reOrderPoint)

    I get an error message saying

    "The operator < is undefined for the argument type(s) ca1.Food, ca1.Food"

    Any ideas on what this mean?

    Default Re: Error with code

    The compiler is telling you that Java has no idea how to determine if one Food is "less than" another Food. Unfortunately (or fortunately depending on who you ask) Java doesn't allow you to override/overload the operators set so you must use a method call (perhaps something like compareTo())
