Question

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: $10 + $2 per topping Medium: $12 + $2 per topping Large: $14 + $2 per topping

A public method named getDescription( ) that returns a String contain- ing the pizza size, quantity of each topping, and the pizza cost as calculated bycalcCost( ).

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.

public void getDescription( )
{
System.out.println(" Main size is " + size + " number of cheese toppings " + get_no_of_cheese_toppings() +

System.out.println(" cost of this pizza is " + calcCost());
}

public static void main(String[] args)
{
Main a = new Main();
a.set_size("large");
a.set_no_of_cheese_toppings(1);
