I am trying to create a program that makes a list of food items in an array list that can be used to create food orders. I have started on the arraylist of food items but I don't understand how to calculate the price and how to store the orders. This is the code I have so far which I know is pretty pathetic at the minute:-
One problem here is that the add() method, as you've used it, expects an object and cannot take a primative.
This section works because String is a class and description is an object
This part fails to compile because int's are primatives not objects:
There may be other problems, but it seems like this is the first step. You can use the Integer class instead of an int to place a numerical object in an ArrayList - it seems like situations like this are what the wrapper classes are made for. [ November 28, 2004: Message edited by: Randall Julian ]
