Python Programming 2. Write a class named Pet, which should have the following data attributes: (a). __name (for the name of a pet) __animal_type (for the type of animal that a pet is. Example values are ‘Dog’, ‘Cat’, and ‘Bird’) __age (for the pet’s age) The Pet class should have an __init__ method that creates these attributes. It should also have the following methods: (b). set_name: This method assigns a value to the __name field. set_animal_type: This method assigns a value to the __animal_type field. set_age: This method assigns a value to the __age field. get_name: This method returns the value of the __name field. get_animal_type: This method returns the value of the __animal_type field. get_age: This method returns the value of the __age field.

B. Pet Class Using Python Program, Write a class named Pet, which should have the following data attributes: • _ _name (for the name of a pet) •__animal_type (for the type of animal that a pet is. Example values are 'Dog', 'Cat', and `Bird')' __age (for the pet's age) init The Pet class should have an method that creates these attributes. It should also have the following methods: set_name() This method assigns a value to the __name field. set_animal_type() This method assigns a value to the __animal_type field. • set_age() This method assigns a value to the • get_name() This method returns the value of the get_animal_type() This method returns the value of the __animal_type field. • get_age() This method returns the value of the _age field. Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored as the object's attributes. Use the object's accessor methods…

Computer programming

Exercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the account

Using C# language: Programming PLO-2 Measured: Design, implement, and evaluate computer solutions utilizing structured and object-oriented programming methodologies.   Design a class named Contractor. The class should keep the following information:   Contractor name Contractor number Contractor start date   Write one or more constructors and the appropriate accessor and mutator functions for the class.

JAVA Programming Problem 3 - Book A Book has such properties as title, author, and numberOfPages. A Volume will have properties such as volumeName, numberOfBooks, and an array of book objects (Book [ ]). You are required to develop the Book and Volume classes, then write an application (DemoVolume) to test your classes. The directions below will give assistance. Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. The Book [ ] contains an array of book objects. Directions Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, The only methods necessary in the Book class, for this exercise, are the constructor and a toString(). Create a second class called Volume with the following properties using appropriate data types:…

INVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…

6. Patient Charges Write a class named Patient that has attributes for the following data: • First name, middle name, and last name • Address, city, state, and ZIP code • Phone number ● The Patient class's init__ method should accept an argument for each attribute. The Name and phone number of emergency contact Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: • Name of the procedure • Date of the procedure • Name of the practitioner who performed the procedure • Charges for the procedure 107 The Procedure class's __init__ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute Next, write a program that creates an instance of the Patient class, initialized with sample data. Then, create three…
