Create an application via NetBeans with named Pizza that storesinformation about a single pizza. It should contain the following:• Private instance variables to store the size of the pizza (eithersmall, medium, or large), the number of cheese toppings, the number ofbeef toppings, and the number of chicken 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 thecost of the pizza.Pizza cost is determined by:
Small: OR10 + OR 2 per topping
Medium: OR 12 + OR 2 per topping

- The project downloaded contains a package (folder) named Q3 within the src folder. The purpose of Question 3 is to examine your understanding of classes and inheritance. Inside Q3 is a completed Java class named Location. Location contains three fields: • locationName: name of location (String) • latitude: latitude of location (Double)• longitude: longitude of location (Double) Conceptually, the Location class represents a geographic location (e.g. a city). You do not need to modify the Location class. In this question you will complete an additional class named EuclideanRoute. The fields of the EuclideanRoute class consist of two Location objects named origin and destination. Therefore, a EuclideanRoute object represents the start/end points of a route a vehicle takes. The EuclideanRoute class is derived from the RouteInformation class and the routeDestination method calculates the distance from the origin to the destination using the formula for Euclidean distance. Finally, in the…arrow_forwardWrite a class called Fraction; this class will be designed to handle fractions. The Fraction class has only two instance variables: An integer numerator An integer denominator The two instance variables can be publicly accessible (at this stage). The Fraction class should never store a value of 0 for the denominator. Supply an output method for the Fraction class; this method will be used by the client to print out a fraction (as two separate integers) to the screen. An output fraction would be in the form: numerator / denominator An example: the fraction for a half would be input as 1 for the numerator and 2 for the denominator. The output should be printed out as 1 / 2. Once this is done, write a client class program called TestFraction; this class is to be used to test your Fraction class. Note that the client program should use the Fraction class methods or instance variables (via the dot notation) to get the inputs and display the fractions.
