3 Create a class named Pizza that stores information about a single pizza. It should contain the following: - Private instance variables to store the size of the pizza (either small, medium, or large), the number of cheese toppings, the number of pepperoni toppings, and the number of ham toppings. - Constructor(s) that set all of the instance variables. - Public methods to get and set the instance variables. - A public method named calccost() that returns a double that is the cost of the pizza. Pizza cost is determined by: Small: $1tt+$2 per topping Medium: $12+$2 per topping Large: \$14 + \$2 per topping - public method named getDescription( ) that returns a String containing the pizza size, quantity of each topping. Write test code to create several pizzas and output their descriptions. For example, a large pizza with one cheese, one pepperoni and two ham toppings should cost a total of \$22. Now Create a PizzaOrder class that allows up to three pizzas to be saved in an order. Each pizza saved should be a Pizza object. Create a method calcTotal() that returns the cost of order. In the runner order two pizzas and return the total cost. 2 Write a class Time with three data members to store hr, min and seconds. Create two constructors and apply checks to set valid time. Also create display function which displays all data members
