Join Peggy Fisher for an in-depth discussion in this video Challenge: Pizza ordering app, part of Java Essential Training for Students.
- Are you ready for the next challenge?…In this challenge, I've tried to include…several of the concepts we reviewed in this section.…We've been contacted by a friend who owns a pizza shop.…She wants an application that supports online ordering.…After talking to the owner,…we decide to create the following.…A pizza class that implements the comparable interface.…Again, this is for a pizza shop,…and this particular pizza shop offers two types of pizza…Regular and Sicilian.…The Regular is circular,…but the Sicilian is formed in the shape of a rectangle.…
We will have a super class for pizza…with two sub-classes, Regular and Sicilian.…The comparison will be used to sort the pizzas…based on size, small, medium, large, and extra large.…The pizza class needs to include…the size of the pizza,…the type of pizza, toppings,…we'll include an ArrayList of strings…to allow for multiple toppings,…and the cost of the pizza.…The main program will ask the user for the…customer name,…the type and size of the pizza they would like to order,…

Q: How can I make my debugger function like the author’s?
<div>A: When you are debugging your program in NetBeans, if you do not see the new contextual items on the menu bar for stepping into your code, check to see if the source file is accidentally deselected.</div><div> </div><div>Highlight the program you want to debug in your projects folder. In the menu bar, choose Windows > Debugging > Sources. A new window will appear with the file path name. If the checkbox is not selected, click the box to select this file.</div><div> </div><div>Now you can go back to your program and rerun the debug operation on your code.</div>
