Answer 1

Pizza class:

The Pizza class represents a pizza order. It has fields to store the customer's name, pizza size, number of toppings, and cost of the pizza. Write the Pizza class with these requirements:

• Add the 4 fields used by this class. All fields should be set to private, and use descriptive variable names.
• Create a constructor that takes 3 parameters: a String to initialize the customer name, a String to initialize the pizza size (small, medium, or large), and an int to initialize the number of toppings. The cost will be initialized using the calculateCost method described below.
• Write an accessor method named getName that returns the name from the order.
• Write a mutator method named calculateCost to calculate the cost of the pizza order as follows:

  A small pizza is $8, and toppings are $1 each.

  A medium pizza is $10, and toppings are $2 each.

  A large pizza is $12, and toppings are $3 each.

  Additionally, if the customer orders 4 or more toppings, there is a $2 discount of the price of the pizza, regardless of the size.

  This method will set the cost of the pizza.

• Write an accessor named getCost that returns the cost of the pizza.
• Write a mutator method named applyDiscount that takes an int parameter and reduces the cost of the pizza by the parameter amount.
• Write a method named printDetails that will print out the Pizza object details as shown below:

  Bales, medium 3-topping pizza: $16

Orders class:

The Orders class represents a number of orders for a pizza shop. It has 4 fields: three Pizza objects, and one String field that stores a day of the week.

• Add the four (4) fields for this class.
• Add the constructor for this class. It takes one String parameter to set the day of the week. Within the constructor, initialize the Pizza objects as follows: ("Bales", "medium", 3), ("Marts", "small", 2), ("Donal", "large", 6).
• Add a method, applyCoupon, that takes one String parameter, a name. It will match the name to the customer name of one of the Pizza objects, and apply a discount of $1, $2, or $3. The amount should be chosen randomly. If there is no Pizza object with this name, an appropriate error message should be printed.
• Add a method called printOrders that will do the following 3 things:
  1. Apply a coupon to the order for Donal
  2. Calculate the total price for all three pizza orders.
  3. Print out the orders as shown below:

     Pizza orders for Wednesday

     Bales, medium 3-topping pizza: $16

     Marts, small 2-topping pizza: $10

     Donal, large 6-topping pizza: $25

     ---------------------------------------

     Total sales for Wednesday: $51

  Keep in mind that your total may be different since the coupon amount was random.
