Object-Oriented Programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data in the form of fields (often known as attributes or properties) and code in the form of procedures (often known as methods). This tutorial will provide a basic understanding of OOP principles and demonstrate how to implement them in a programming language.

Key Concepts of OOP

  1. Class: A blueprint for creating objects. It defines the properties and behaviors that the objects will have.
  2. Object: An instance of a class. It is a real-time entity that has state and behavior.
  3. Inheritance: A mechanism that allows a class to inherit properties and methods from another class.
  4. Polymorphism: The ability of objects of different classes to be treated as objects of a common superclass.
  5. Encapsulation: Hiding the internal state of an object and requiring all interaction to be performed through an object's methods.

Example: Creating a Car Class

Below is a simple example of a Car class in Python:

class Car:
    def __init__(self, make, model, year):
        self.make = make
        self.model = model
        self.year = year

    def display_info(self):
        print(f"Make: {self.make}")
        print(f"Model: {self.model}")
        print(f"Year: {self.year}")

# Creating an object of the Car class
my_car = Car("Toyota", "Corolla", 2020)

# Calling a method on the object
my_car.display_info()
