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:

Step by step
Solved in 2 steps
- When designing a class that implements Comparable, what design patterns or principles should be considered to promote code reusability and maintainability?The entire list of parent classes from which a child class is derived constitutes the ____ of the subclass. a. children b. derivatives c. subordinates d. ancestors* When class B is inherited from class A, what is the order in which the constructers of those classes are called class a's only as it is the parent class O class b's only as it is the child class O class b first class a next O class a first class b next O
- If a class is derived privately from the parent class then . Select one: a.the compiler gives an error b.all the members are inherited by the child class but are inaccessible c.no members of the base class is inherited d.all members are accessible by the child classThe pillar that allows you to build a specialized version of a general class, but violates encapsulation principles isT F Classes are good for creating scalable and maintainable code
- The ability to create classes that share the attributes and methods of existing classes but with more specific features is known as : Abstraction Polymorphism Typecasting InheritanceIn-class Assignment Day 8 You should draw the hierarchy for your classes to understand how the coding should be structured. Be sure to notate any classes that are abstract. Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example: Triangle, Area: 7.5, Perimeter: 12.0 Write the class Rectangle. A Rectangle is a Shape and should have a width and a height. When a Rectangle is outputted, it should read: Rectangle, Length: #, Width: #, Area: #, Perimeter: # Write the class for Circle. Every circle is a Shape that has a radius. Be sure to provide an accessor method (getter) for the radius. When a circle is outputted, it should read: Circle, Radius: #, Area: #, Circumference: # Write a TestShape class that has the main method, which creates…HAS-A relationship between the classes is shown through. A - Inheritance B - Container classes C - Polymorphism D - None of the above.
- Programming Assignment #5 Educational Objectives: After completing this assignment the student should have the following knowledge, ability, and skills: Define a class hierarchy using inheritance Define virtual member functions in a class hierarchy Implement a class hierarchy using inheritance Implement virtual member functions in a class hierarchy Use initialization lists to call parent class constructors for derived class constructors Operational Objectives: Create (define and implement) a base class Shape classes that will inherit this class called Box, Rectangle, Circle, and Triangle Description: Programming Specifications: You will have a base class of Shape which will have an area and perimeter of type double. You must also create acceptable Gets and Sets for the private data items. All of the other classes will inherit this class. You will have a class Square which will have just one length of type double. You should create acceptable Gets and Sets for the one…Library Management System Develop a Library Management system for borrowing and returning activities The basic classes could be the main Library, Subscribers, borrowing records, Contents, articles, e.t.c. NB: Contents may include books, journal articles or digital media. Also a subscriber may borrow books for one month, after which a fee accrue until the borrowed item is returned. On the other hand, golden subscribers may borrow for 2 months without fee before fees begin. Provides an interface for the user to: A. Adding/editing/deleting instances belonging to each class, B. Subscriber browsing library contents and select items to borrow. C. Subscriber returning borrowed item and check his balance and pay any late fee if any. D. Admin can print reports of overdue borrowed items.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.
