c) Suppose we have a class User which has a constructor with the header User (String name, Account account) where name gives the name of a person who is to be the User, and account gives the Account, which belongs to the User. Write a class UserFactory that creates User objects, but if a User object with the same name and same account already exists, it returns that User object rather than a new User object. The class User has a method getName() that returns the name of the User and getAccount() which returns the Account of the User. This is an example of the Factory Object design pattern.

1) Define a Person class containing two private attributes: last name, first name. Provide this class with a constructor allowing the initialization of its attributes and a method that displays the last name and first name of a person: void display (). 2) Define a Customer class inheriting from the Person class and having a private attribute: numidentity. Provide this class with a constructor allowing you to create a customer from their last name, first name and identity card number and a method: • void display() which displays the last name, first name and ID number of a customer. 3) Define an Owner class inheriting from the Person class and having two private attributes: name of the video club (nomclub), address of the club (adrclub).

Design and implement an object-oriented program for displaying a deck of cards. Each card will have a value ranging in order from 1 for an ace, 2 for a two, and so on up to and including 11 for a jack, 12 for a queen, and 13 for the king. The focus of the exercise is to create three classes that represent a card, deck, and hand using composition.
1. Inheritance Create a class named Person and its two subclasses named Student and Employee. Then create Faculty and Staff as subclasses of Employee. A Person has a name, address, phone number, and email address. Each of these will be String objects. A Student has a class status which will be an int ( 1 for a freshman, 2 for a sophomore, 3 for a junior, or 4 for a senior). An Employee has an office (String), salary(int), and a date hired(String). A Faculty Member has office hours (String) and a rank which will be an int(1 for a Lecturer, 2 for an Assistant Professor, 3 for an Associate Professor, or 4 for a Professor). A Staff member has a title. Each class will have a toString() method to display the name of the class and the person’s name. For a Student, the toString() method will also return the class status (freshman, sophomore, junior, senior), for an Employee, the salary, for a faculty member, the rank (Lecturer, Assistant Professor, Associate Professor,…

Design and implement a class dayType that implements the day of the week in a program. The classdayType should store the day, such as Sun for Sunday. The program should be able to perform thefollowing operations on an object of type dayType:a) Set the day.b) Print the day.c) Return the day.d) Return the next day.e) Return the previous day.f) Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday.g) Add the appropriate constructors.The class dateType was designed to implement the date in a program, but the member function setDateand the constructor do not check whether the date is valid before storing the date in the member variables.Rewrite the definitions of the function setDate and the constructor so that the values for the month, day,and year are checked before storing the date into the…
Step-1 Imagine a Car Parts and Accessories shop, which requires a software system to keep track of stock items and prices. The shop will sell different kinds of stock items. However, to start with, you have been tasked with designing and implementing a class called StockItem with the following properties. An instance (object) of the StockItem class represents a particular item which the shop sells, with a string representing fixed stock code, an integer representing variable quantity in stock and a double representing variable price of the stocked item. All these variables should be declared as private variables. The StockItemclass also contains a class variable (shared by all instances) of type string representing stock category which you can initialise as 'Car accessories'. A constructor that creates a Stock Item with the specified quantity, price and the stock code. All the appropriate ‘setters’ and ‘getters’ methods, including a getStockName() method which returns the string…

1. Design a new Triangle class that extends the abstract GeometricObject class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.
