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:

- Class A is a subclass of B. The statement A myA = new A(); B myB = myA compiles successfully. This statement shows the concept of inheritance. True or FalseClass definitionDefine a class bankAccount to implement the basic properties of a bank account. Anobject of this class should store the following data: Account holder’s name (string) Account number (int) Account type (string, check/savings/business) Balance (double) Interest rate (double) – store interest rate as a decimal number. Add appropriate member functions to manipulate an object. Use a static member in theclass to automatically assign account numbers.KOTLIN: Classes and Inheritance Given the Pet as the parent class of the Cat, Dog, and Fish. Complete the code so that each instance of Cat, Dog and Fish can shows their informations and action as given. //Expected output A pet named Garfield with color Orange do meow A pet named Pluto with color Black do barks A pet named Jenny with color Gold do Swim
- Complete the thick.h, thick.cpp, thin.h, and thin.cpp classes in the attached pizza solution. Modify your main.cpp class so that it creates a thin and thick crust pizza if selected by the user. Your solution should allow the user to order a regular, stuffed, thin or thick crust pizza. All child classes (stuffed, thin, thick) should inherit attributes and functions from the Pizza class. The stuffed class has already been implemented. The thick and thin class set_cost() funtions should differ in the following ways: thick crust has an additional charge of $2 thin crust has a cost discount of $1(Java) Make the 2 following classes: Employee.java EmployeeTest.java Copy and paste the below starter code into Employee.java: /** * Employee.java extends Person.java * @author * CIS 36B, Activity 11.1 */public class Employee extends Person { private static int numEmployees = 0; private double salary; private String title; /** * Default constructor for the * Employee class. Calls the * default constructor of the * superclass and also initializes * salary and title to default * values */ public Employee() { } /** * Multi-argument constructor for the * Employee class. Calls the * multi-argument constructor of the * superclass and also initializes * salary and title to the * specified values */ public Employee(String name, int age, String gender, Address a, double salary, String title) { } /** * Returns the annual salary * @return the salary */ public double…True or False A subclass can override methods from its superclass.
- When the inheritance is private, the private methods in base class are __________ in the derived class (in C++).a. Inaccessibleb.. Accessiblec.. Protectedd. PublicClass Inheritance with abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as: name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the employee works…Create a class Reverse with one data member called num of type int and a static method find to return reverse of num. Create a subclass ReverseR from Reverse which overrides member of its super class. Write a main() method that tests in same class ReverseR. method find()) and this override method uses recursion to find and returns reverse of data
- In Python doINHERITANCECreate the inheritance relationship by doing base class People, derived class StudentDetermine if this statement is true or false Take the following method, which is defined in some class: class SomeClass: SomeBaseClass{ private int override MyMethod() { //do something.... } } This is an example of run time polymorphism, as MyMethod is being redefined in the child class by the override keyword.Public members of a base class can be accessed by anything from outside the base class. Private members can be accessed only by the base class and derived classes. Protected members can be accessed by the base class and any of its descendants (child class or child of a child class). answer choices True False
