OOps in java is to improve code readability and reusability by defining a Java program efficiently. With inheritance, an object can be extended and code from the parent object can be reused or overloaded in the child object. For example, we treat duck as an animal and not just as a duck. Polymorphism is a feature of OOP that serves the purpose of OBJECT-ORIENTED PROGRAMMING OBJECT-ORIENTED PROGRAMMING PROMOTES MODULARITY AND REUSE It is often claimed that object-oriented programming is a better way of writing more modular programs leverages code sharing and design reuse minimises maintenance costs Thanks to its abstraction mechanisms 10. Data transfer is not a feature of OOP. A properly defined class can be reused, giving way to code reusability. 4. With an object of a class, we can access the data members and member functions that can be accessed (as per the private, public, protected accessibility scope).

Here, data and action can be redesigned and reused when required. This mechanism actually inherits the fields and methods of the superclass. Object-oriented programming (OOPs) is a programming paradigm that is based on the concept of objects rather than just functions and procedures. Answer: The 4 basic features are inheritance, polymorphism, encapsulation and abstraction. a. Encapsulation. All the other options are incorrect and do not indicate code reusability except Inheritance. Encapsulation is used to hide the values or state of a structured data object inside a class, preventing unauthorized parties direct access to them.

It has the capability of storing your Contacts. The time effort of developers can also be reduced with inheritance, and it provides a better understanding of code to other developers as well, working in a team. The main idea behind Object Oriented Programming is simplicity, code reusability, extendibility, and security. Fundamentals of OOPS Concepts in C++ - EnjoyAlgorithms For a language to be classified as OOP, it must have these 4 OOP blocks. Code reusability is done using inheritance.

Its one of the most important OOP concepts. These objects can contain the data (attribute) and the methods (behavior), just like real-life entities that we model into our applications. Polymorphism is a feature of OOP that serves the purpose of indicating different tasks that are carried out a one entity. Create a function that will accept as arguments two integers and the name of the individual to some function void createContact that will be defined later (String name, int number1, int number2). Inheritance. Polymorphism refers to the ability of a programming language to provide the same interface for a variety of underlying data types. a) Overloading <<* b) Overloading && c) Overloading | | d) Overloading +=. A class is a generic template that you may use to create more specialized, concrete things.

Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or superclass or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class.This whole set of mechanism is known as Inheritance. And when it comes to reusing code in Python, it all starts and ends - Selection from Head First Python, 2nd Edition [Book] It is essentially taking code from one part of a program and attempting to employ it elsewhere without having to alter too much. The ability to inherit the properties of one class to another, or inherit the properties from a base class to an inherited class is known as the concept of Inheritance. Of basic terms, Objects are the fundamental data types in object-oriented programming languages and are used to build object-oriented programming.
