I am new to Java programming. I developed a Pizza class that takes for parameters and outputs the description and cost. I developed a PizzaOrderArray class that stores the pizza orders in an array. I have a class containing the main method also.
When I tried to print the values of the orders, nothing prints yet debugging shows that the proper methods and loops were entered.
What am I doing incorrect? I have invested many hours and am still very confused. Any suggestions, please? Thank you! I appreciate it.
