Need help on Arrays and objects
Okay here's what i'm trying to do. I want to create an array and fill it with objects, so that when i create a method to alphabetize them, all of the pieces (the price, name, ect) don't get all out of order and correlate to each other.
Here is my code so far... any ideas?
Just need to create an array of classes. How do i get all these items i created into it?
(Just the section by Main)
