- WRITE JAVA CODE FOR THE FOLLOWING Create a class named Pizza with the following data fields: description - of type String price - of type double The description stores the type of pizza (such as sausage and onion). Include a constructor that requires arguments for both fields and a method named display() to display the data. For example, if the description is 'sausage and onion' and the price is '14.99', the display() method should output: sausage and onion pizza Price: $14.99 Create a subclass named DeliveryPizza that inherits from Pizza but adds the following data fields: deliveryFee - of type double address - of type String The description, price, and address are required as arguments to the constructor. The delivery fee is $3 if the pizza ordered costs more than $15; otherwise it is $5. Add a display() method to the DeliveryPizza class. The display() method should print the information from the display() method in the super class (Pizza) in addition to the address and…arrow_forwardIn python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year.

The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…arrow_forwardplease quickly thanks ! use javaarrow_forward
