I am creating a program that makes a list of products that are used to create orders which are added to an orders queue. The thing is I don't know the first thing about arraylists and just can't understand what I need to do. This is my code so far:-
So far all I have is a list of methods that I don't know how to use. How do I store food items in an order if each arraylist can only hold one object. I am so confused and am considering throwing the towel in.
