Question

1. Define a class called PizzaOrder that represents a pizza order for a customer. This class has 4 private data members: size -- an integer representing the size of the pizza in inches. Valid values are 10, 15, 22. toppings -- a string representing a list of the toppings: "pepperoni,olives". Each item is separated by commas and there are no spaces. crust -- A string representing the type of crust. Valid values are "thin", "pan", and "handtossed". name -- A String representing the customer's name. Write a set/get method for each private variable -- for example, setSize(int s) sets the variable size to the value s. Likewise, getToppings( ) returns the value of toppings. 2. Write an application that uses your PizzaOrder class. First, your application will prompt the user for name, size of pizza, toppings, crust. Then create a PizzaOrder object and call the set methods on that object for each part of the order. After you have called the set methods, call the get methods of the object to retrieve and display the values of the object. Example: What size pizza do you want: 10 What toppings: pepperoni,onions,olives What kind of crust: pan What is your name: Allen Here is your order: Pan pizza 10 inch pepperoni,onions,olives For Allen
