A library wants to manage its collection of books and authors more efficiently. They would like to create a Python program to help with this task. The following requirements need to be implemented: Create an Author class with the attributes: name, dob (date of birth), and nationality. The class should have a __str__ method to represent the author in a user-friendly format. Create a Book class with the following attributes: title, author (an instance of the Author class), publication_date, and price. Also, include a class variable all_books that keeps a list of all book instances created.The Book class should have: A __str__ method to represent the book in a user-friendly format. A __eq__ method to compare two books. Two books are considered the same if they have the same title and author. A __lt__ method to compare two books based on their publication dates. A class method get_all_books that returns a list of all books in the library. A static method most_expensive_book that takes…
Please help with the following: C# .NET change the main class so that the user is the one that as to put the name in other words. Write a driver class that prompts for the person’s data input, instantiates an object of class HealtProfile and displays the patient’s information from that object by calling the DisplayHealthRecord, method. MAIN CLASS---------------------- static void Main(string[] args) { // Instance created holding 6 parameters which are field with value HealthProfile heartRate = new HealthProfile("James","Kill",1978, 79.5 ,175.5, 2021 ); heartRate.DisplayPatientRecord();// call the patient record method } CLASS HeartProfile------------------- public class HealthProfile { // attibutes which holds the following value private String _FirstName; private String _LastName; private int _BirthYear; private double _Height; private double _Weigth; private int _CurrentYear; public HealthProfile(string firstName, string lastName, int birthYear, double height, double wt, int…
In java ,A subclass constructor cannot catch exceptions thrown by its superclass constructor. Is this statement true or false? Write a code that demonstrates your claim.
A registration officer in an academic institution wants to display the Student transcript in a given semesterafter entering the required student details. A student is characterized by an ID, full name, the semester inwhich he/she is registered and other details. The student can take from 3 to 4 modules every semesterand has two assessments in each module.You are requested to write the program that will help the officer to display the indicated transcript usingClasses, methods, arrays and various control statements. Create the class Student, which must have a normalconstructor and at least 5 attributes. attributes: ID , full name, Semester Gender , Age (JAVA)
Must be written in Python. Please include docstring and show how output should look like. Remember that all data members should be private. An object can access it's own private data members directly. It can also access the private data members of other objects of the same class directly. But when accessing a private data member of an object of another class, it needs to call the appropriate get method. If that sounds complicated, just remember this: if a method is in the same class as a private data member, then it can access that data member directly, otherwise, it needs to use a get method. Write a class named Point that has two data members, x_coord and y_coord, representing the two coordinates of the point. It should have: an init method that takes two arguments, an x-coordinate and y-coordinate (in that order), and uses them to initialize the two data members. get methods for the two data members: get_x_coord and get_y_coord. a method named distance_to that takes a Point object…
Create a class MyTime which has the datamembers as follows: 1. hour: integer (1 to 12)2. minute: integer (0 to 59)3. second: integer (0 to 59)4. pm: bool variable. True means PM time and false means AM time. Implement a default constructor, a parameterized constructor and a copy constructor. Write set and get functions for all the four members of the class. Overload these operators: 1. Extraction operator >> : Prompt the user for hours, minutes, seconds and for am/pm and initialize the structure. Left operand istream object and right operand MyTime2. Assignment = : Assign the right object to the left object. Both operands are of type MyTime.3. Insertion << : Print the time in the format HH:MM SS PM. Left operand of type ostream and right operand of type MyTime. this in c++.
16. Create a class SubstitutionCipher that implements the interface MessageEncoder, as described in the previous exercise. The constructor should have one parameter called shift. Define the method encode so that each letter is shifted by the value in shift. For example, if shift is 3, a will be replaced by d, b will be replaced by e, c will be replaced by f, and so on. (Hint: You may wish to define a private method that shifts a single character.)
In Python, #Create a basket class, which has a class/static attribute pricelist (string/float dictionary - you can hardcode this) #The constructor should set the name to the name passed as a parameter and initialise the contents (empty) #You should provide an addItem method taking product,quantity which adds this to the contents #and a getQuantity method taking a product, which returns the relevant quantity
Please help with the following: Consider the following Python code:class MyClass: attr = 10a. "altr" is MyClass's instance attribute.b."attr" is MyClass's static attribute.c."attr" is a non-local variable.d."attr" is a local variable.
Overriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.
FOR JAVA Part I Create a Company class that has at least three properties. Part II Write proper constructor and other methods required for the class (get & set, toString etc.) Part III Write at least 5 different methods considering the applications of Company class. Your methods must handle exceptions. Part IV Write a Test class and use the methods written in Company class.
IN C# Write the Gloves class. The Gloves have a color, size (S, M, L, XL), and a price. a. Implement data fields using auto-implemented Properies b. Include 3 constructors: default, the one that receives the Gloves color, size and a price as input (utilize the Properties) and the Constructor that takes the Gloves material (a String) as input. Test your class in the main method c. Create 3 instances of the class using the Constructors you created. d. Create one more Gloves using an Object Initializer.
