Object Oriented Programming

Short Answer
Object-Oriented Programming (OOP) is a programming paradigm where programs are organized around objects and data rather than actions.

Object Oriented Programming

Definition

Object-Oriented Programming (OOP) is a programming paradigm that uses "objects" – data structures consisting of data fields (attributes) and methods (functions) – to design and create software systems. Key principles include encapsulation (data hiding within objects), inheritance (sharing attributes and behaviors among classes of objects), and polymorphism (ability to process objects differently based on their data type or class). OOP aims to improve software development by modularizing code for reusability, scalability, and easier maintenance. Languages such as Java, Python, C++, and Ruby are popular for OOP due to their support for classes, objects, and inheritance.

Object Oriented Programming

Examples

Class and Object in Java:

  • In Java, a "Car" class can define attributes (e.g., model, color) and methods (e.g., drive(), stop()). An "object" of this class represents a specific car instance.
  • Inheritance in Python:
    • A "Vehicle" class can have subclasses like "Car" and "Truck," inheriting common attributes and methods from the parent class while adding their own unique features.
  • Encapsulation in C++:
    • Encapsulation hides sensitive data within a class, allowing controlled access through public methods (getters/setters) in C++ classes like "BankAccount."
