A class called Author is designed to model a book's author. It contains:• Three private instance variables: name (String), email (String), and gender (char of either'm' or 'f');• An __init__() to initialize the name, email and gender with the given values• Getters/Setters: getName(), getEmail(), setEmail(), and getGender()(There are no setters for name and gender, as these attributes cannot be changed.)• A __str__() method that returns printable string of that object with the following format:"Author[name=?,email=?,gender=?]"e.g., "Author[name=Tan Ah Teck,email=ahTeck@somewhere.com,gender=m]".Write the Author class. Also write a test driver code to test all the public functions, e.g.,ahTeck = Author("Tan Ah Teck", "ahteck@nowhere.com", 'm') # Test the constructorprint(ahTeck) # Test __str__()ahTeck.setEmail("paulTan@nowhere.com") # Test setterprint("Name is: ", ahTeck.getName()) # Test getterprint("Email is: ", ahTeck.getEmail()) # Test getterprint("Gender is: ", ahTeck.getGender()) #…

Design an Essay class that is derived from the GradedActivity class presented in thischapter. The Essay class should determine the grade a student receives on an essay.The student’s essay score can be up to 100, and is determined in the following manner:• Grammar: 30 points• Spelling: 20 points• Correct length: 20 points• Content: 30 pointsDemonstrate the class in a simple program.
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…

Write the code below for the Computer class. The Computer class must be an abstract class, and have the following methods and attributes: • a public string called HostName • a private int called MemorySize • a public abstract method called shutdown that takes no arguments and returns nothing • a public abstract method called runProgram that takes a String for the name of the program and returns a boolean. • Also include getter/setter methods for the attributes
Consider an example of declaring the examination result. Design three classes:Student, Exam and Result. The Student class has data members such as thoserepresenting roll number, name etc. create a class Exam by inheriting the student class.The exam class adds data members representing the marks scored in six subjects.Derive class Result from the exam class and it has own data members such as total_marks. Write an interactive program to model this relationship. What type ofinheritance this model belongs to?
A small airline company is developing software to control its operations. You should design and develop a class that will be used to create objects that hold information about flights. The information kept about each flight includes: ● Flight number • Departure time • Seat capacity Seats sold Flight destination Flight departure point (i.e. Dublin, Cork, etc.) When creating a flight object the flight number, departure time, seat capacity, flight destination and departure point are given. Behaviour Functions of this class: • Default Constructor - initialises all data members. Constructor that takes the flight no as input parameter and request user input, departure time, seat capacity, flight destination, flight departure point, flight time. ● • A check_available_seats function that returns the number of unsold (still available) seats on a flight; • A sellseats function that takes as a parameter the number of seats a customer requires on a flight. If there are sufficient seats available…
Create an Employee Class that will have Two instance variable: name and workingPeriod A class method named employeeByJoiningYear(): • To create an Employee object by joining year for calculating the working period o it will have two Parameter name and year • A static method experienceCheck() to check if an Employee is experienced or not o It will take working period and gender as parameter o If an employee's working period is less than 3, he or she is not experienced [You are not allowed to change the code below] # Write your code here employee1 = Employee('Dororo', 3) employee2 = Employee.employeeByJoiningYear('Harry', 2016) 6 print(employee1.workingPeriod) print(employee2.workingPeriod) print(employee1.name) print(employee2.name) print(Employee.experienceCheck(2, "male")) print(Employee.experienceCheck(3, "female")) Оutput 3 Dororo Harry He is not experienced She is experienced
A class called Book is designed to model a book written by one author. It contains:• Four private instance variables: name (String), author (of the class Author you have justcreated, assume that a book has one and only one author), price (double), and qty (int);• An __init__() to initialize the name, author, price, and qty with the given values;• Getters/Setters: getName(), getAuthor(), getPrice(), setPrice(), getQty(), setQty().• __str__() method that returns printable string of that object with the following format:"Book[name=?,Author[name=?,email=?,gender=?],price=?,qty=?".You should reuse Author’s __str__().Write the Book class (which uses the Author class written earlier). Also write a test drivercodeto test all the methods in the class Book. Take Note that you have to construct an instanceof Author before you can construct an instance of Book. E.g.,ahTeck = Author("Tan Ah Teck", "ahteck@nowhere.com", 'm') # Test the constructorprint(ahTeck) # Test __str__()dummyBook = Book("Java…
Create a project to play a bunch of games. Add a class that has main() in it. Create an abstract class called Game. Define one instance variable for the name of the game. Define a constructor that takes the name of the game as a parameter and sets it. Define an abstract method called playGame. It takes no arguments and returns void. Create a child class of Game called BoardGame. Rather than implementing playGame, declare BoardGame abstract. Create a child class of BoardGame called Chess or Battleship or Monopoly or whatever board game you want. Implement the playGame with only a message that says the name of the game and that it is being played. Create a child class of Game called CardGame. Rather than implementing playGame, declare CardGame abstract. Create a child class of CardGame for War. Implement the playGame method by with a message that says the game of war is being played. Create a child class of Game called VideoGame. Rather than implementing playGame,…
