Scoping and Multiple Constructors

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 meat toppings, the number of veggie toppings and whether or not the pizza should be vegan$-$friendly $($in which case you must make sure that the number of meat toppings is $0).$ Discuss with your partner what the difference between a private and public instance variable is$.$

Constructors$$that set all of the instance variables.$$ One constructor should be a no$-$arg constructor, with defaults of medium, no toppings, non$-$vegan.$$ At least one other constructor should enable you to give all the private instance variables a value when you create the object.$$ You should also include error checking to make sure the values you are setting are legitimate $($e$.$g$.,$ there is no such a size pizza as "grande"$).$ Discuss with your partner why there is more than one kind of constructor and when will each constructor be used.

Public methods to get and set the instance variables.$$ Discuss with your partner what would happen if these methods were set to private and why these accessor and getter methods are needed.

A public method named calcCost that returns a double that is the cost of the pizza. Pizza cost is determined by:

Small: $$10$Medium: $$12$Large: $$14$Each meat topping cost $$2$ and each veggie topping cost $$1$If the pizza is vegan, it costs an additional $$2$

A public method named getDescription that returns a String containing the pizza size, whether it is vegan or not, quantity of each topping, and the pizza cost as calculated by calcCost.

Use the provided class named Pizzaria, $($download from above$)$ to test your Pizza class.$$ The Pizzaria class provides test code to create several pizzas and outputs their descriptions.
