OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
With _________________, new classes of objects are derived by absorbing characteristics of existing
classes, then adding unique characteristics of their own.

- A new class of objects can be created conveniently by —----------the new class (called the subclass) starts with the characteristics of an existing class (called the superclass), possibly customizing them and adding unique characteristics of its own.Consider a base class Employeewhich contain basic information of an employee such as: Name(string) Address(string) Id(int) Gender(string) Now create two constructors A default constructor to initialize the data member with default values, A four-argument constructor to initialize data field with user-define values ( must use this key word). Getter and setter function to set and get values of data fields. Derives two classes to show Hierarchical inheritance. A departmentclass which extends the base class employee also have some its own information such as: Department Name(string) Department Id(int). Now create two constructors a default constructor to initialize the data member with default values, a parameterized constructorto initialize data field with user-define values. Appropriate getter and setter function to set and get values of data fields. A display method to show all the records of employee along with department information. Create another child class Loanwhich extends the…How do I solve this practise exercise below with Swift code? (Creating a Subclass) Note: The exercises below are based on a game where a spaceship avoids obstacles in space. The ship is positioned at the bottom of a coordinate system and can only move left and right while obstacles "fall" from top to bottom. Throughout the exercises, you'll create classes to represent different types of spaceships that can be used in the game. The base class Spaceship has been provided for you below. Define a new class Fighter that inherits from Spaceship. Add a variable property weapon that defaults to an empty string and a variable property remainingFirePower that defaults to 5. Create a new instance of Fighter called destroyer. A Fighter will be able to shoot incoming objects to avoid colliding with them. After initialization, set weapon to "Laser" and remainingFirePower to 10. Note that since Fighter inherits from Spaceship, it also has properties for name, health, and position, and has methods for…
- a package ParentPackage, define a class Code Tantra with the instance variables-student name, registration number, a float array of length 7 (to store the marks scored in 7 questions in TermEnd exam), total marks and percentage. Define a constructor that receives the name, registration number and an array of 7 marks and adds the top 5 marks and stores the sum in total marks in the same package, define a class Percentageclass with a method to calculate the percentage Define a subpackage ChildPackage" with a class GradeClass that inherits the PercentageClass and includes a method to print the count of S. A. B, C D E and 'F' grades, based on the percentage obtained(Java Code)1. a class Rodent has two subclasses Rat and Mouse. Rodent has the public method "squeak" and Rat has the public method "hiss." Which of the following statements will cause a compiler error? A. Rat rat = new Mouse(); B. new Rodent().hiss(); C. new Mouse().squeak(); D. A and B but not c will compiler errors E. A, B and C will cause compiler errors 2.

- Implement a JAVA application that keeps track of package deliveries to consumers. Theapplication consists of the following classes:• Item: Create a class called Item. The class has two member variables oftype String named name and description and provides getter and settermethods for both.• Mail (abstract class): Implement an abstract class called Mail . The class hasa member variable of type String named address and a getter method for it.• Letter: Implement a class called Letter that inherits from Mail . The classhas one member variable of type String named contents.• Package: Implement a class called Package that inherits from Mail . Theclass has one member variable of type Item[] named items and a gettermethod for it.• DeliveryTruck: Implement a class called DeliveryTruck with a singlemember variable of type Mail[] of length 10. Add the following method:o void load(Mail mail): This method stores the given mail argumentat the next available spot in the member variable.Q1: Write a class named as Bus that contains the attributes which are mentioned below: The name of Bus. The direction of Bus (North (N), South(S), East(E), West (W)) The position of Bus (from imaginary zero point)The class has the following member functions: A constructor to initialize the attributes Turn function to change the direction of bus to one step right side (e.g if the direction isto East, it should be changed to South and so on) Overload the Turn function to change the direction to any side directly. It should take thedirection as an argument. Move function to change the position of the Bus away from imaginary zero point. Itshould accept the distance as an argument.Consider a base class Employee which contain basic information of an employee such as:Name(string)Address(string)Id(int)Gender(string)Now create two constructors A default constructor to initialize the data member with default values, A four-argument constructor to initialize data field with user-define values ( must use this key word).

- C++ Create a Human class with the following features: Each Human needs a name, an age, and some phrase that they say. Each Human needs appropriate getters and setters for all attributes. For every interaction with this human, increment the age by 1 year. Default constructor with no arguments. Constructor that takes the name, age, and phrase arguments\ Create a driver to demonstrate all of the features of your Human class. The driver is the only class with main().The driver must create a dynamic array of Human Objects of some user-defined size. This requires prompting the user for a number of Humans to create.Be sure to iterate through your array of Humans. Interact with every Human object. Demonstrate ALL features of the Human class.(JAVA) Create a class hierarchy to represent the different types of employees in an office who have the following job titles: manager, assistant, salesperson. Write an abstract base class called Employee that declares an abstract method: signature double calculateSalary() This class must also define the following attributes: name (String type), enrollment (String type) and base_salary (double type). Use encapsulation and provide a constructor that receives the corresponding values to be stored in the respective attributes. This abstract class must be extended by the other classes representing the types of employees, so the classes Manager, Assistant and Salesperson must be written. In each class you must override the method calculateSalario so that the salary calculation is done like this: The manager receives twice the base_salary, the assistant receives the base_salary and the salesperson receives the base_salary plus a commission defined in the constructor of his class. Create a…Discuss the concept of multiple interfaces in a single class. What are the advantages and potential challenges of implementing multiple interfaces in a class?
