in the date classOverload the constructor method as the class diagram showsIn the main program, create three objects of class date, one from each of the constructors.In the main program, overload the showdate method to display the date in the following formatsThe date in dd/mm/yy formatThe date in dd/mm formatThe date in “d of month” formatIn the main program, make use of each of the showdate methods, one with each of the created objects.Send your two files, the date file and the main program where you use the date constructor overload and the showdate method overload.
Please code in python Create a program with two classes – the person class and the student The person class has the following properties: first name (first_name), last name (last_name) street address (address) city (city) zip code (zip) The class has the following methods: get_full_name, which returns the full name of a person get_full_address, which return greeting, returns a greeting message. The class should provide accessor and mutator for each property The class should override the __str__ method to return the state of the object. Create a child class called student which has a property named graduation year (graduation_year) and major. Provide accessor and mutator for each property of its own It inherits all the properties and methods of the person parent class as well. Create a test program that Create an object of the person class and print the full name of a person. Create an object of the person class and print…
Classes: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit. Deliverable: Submit your source code and classes on Github (you will be supplied an account) You will also submit a Word document and your code on Canvas. In the document you iwll write a summary of your design…
C- Create the sub class UsedBook that is derived from the super class Book and has the following instance variables, constructor, and functions: title ( String) isbn ( String) authors (String) publisher (String) edition ( int) published_year (int) price_new (double) // the price of the book if it is new age (int) // how old the book is in years Constructor that takes all of the above variables as input parameters. set/get functions calculate_price method // the price is calculated as price_new * (1- 0.10*age) print function that prints all information related to the old book. D- Create the Testing class that has the main method and does the following: aa- Use the constructor to create instance of NewBook class and name it as new. Call compute_price function. bb- Use the constructor to create instance of usedBook class and name it used. Call compute_price function. cc- Print the related information of new and used objects using print functions. Use this following code: class…
A cash processing company has a class called Account used to process transactions: Method/Constructor Description public Account (Client c) public boolean process (Transaction t) constaucts an account using client information processes the next transaction, returning true if transaction was approved, false otherwise Account objects interact with Transaction objects, which have many methods including: Method/Constructor Description returns the value of this transaction in pennies (could be negative, positive or zero) public int value() The company wishes to create a slight modification to the Account class that filters out zero-valued transactions. Design a new class called FilteredAccount whose instances can be used in place of an Account object but which include the extra behavior of not processing transactions with a value of 0. More specifically, the new class should indicate that a zero-valued transaction was approved but shouldn't call the process method in the Account class to…
Object-oriented programmingProgram the employee class as indicated in the diagramTo calculate the salary, just multiply the number of hours by the payment per hour.The capture method asks the user for the data for the three attributes, asks for the hours worked and the payment per hour and with these data calculates the salary.The show method displays all of the employee's data.Do not forget the getter and setter methods only for attributes of type privateYour company has 7 employees and you would like1. Capture the data of each employee2. Show the data of each employee3. Show the data of a particular employee4. Calculate and display the average salary5. Calculate and display the name of the employee with the highest salary6. Calculate and display the name of the employee with the lowest salary7. Calculate and show the total payment you will make for all your employees
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

Python Code please Point of Sale Write a program that will manage the point of sale in a store. Build the ItemToPurchase class with the following: Attributes item_name (string) item_price (int) item_quantity (int) Default constructor Initializes item's name = "none", item's price = 0, item's quantity = 0 Method print_item_cost() Example of print_item_cost() output:Bottled Water 10 @ $1 = $10 Extend the ItemToPurchase class to contain a new attribute. item_description (string) - Set to "none" in default constructor Implement the following method for the ItemToPurchase class. print_item_description() - Prints item_description attribute for an ItemToPurchase object. Has an ItemToPurchase parameter. Example of print_item_description() output:Bottled Water: Deer Park, 12 oz. Build the ShoppingCart class with the following data attributes and related methods.

1. A method stub is a) a short method b)a method with an abrupt end c)a method whose header has not yet been written d) a method whose statements have not yet been written 2 An abstract class can always be instantiated as an object can sometimes be instantiated as an object can often be instantiated as an object can never be instantiated as an object 3)When a derived class defines a member method that has the same name, parameters, and return type as a base class's method, the member method is said to overload the base class's method overreach the base class's method override the base class's method overshadow the base class's method 4. What would be the best code to print out all the elements of an array for (int i = 0 ; i <= arry.length ; i++ ) System.out.println(arry[i]); for (int i = 0 ; i < arry.length ; i++ ) System.out.println(arry[i]); for (int i…
