Classes and Objects

Classes and Objects

Defining and Creating Classes In Object-Oriented Programming, classes serve as templates for creating objects. They define the structure and behavior that objects will have through properties and methods. Defining a Class A class is defined using a specific syntax in programming languages like Python, Java,

Introduction to OOP

Introduction to OOP

What is Object-Oriented Programming? What is Object-Oriented Programming? Object-Oriented Programming (OOP) is a programming paradigm based on the concept of “objects,” which contain data and behavior. It helps structure code into reusable and organized components that mirror real-world entities. Core Concepts of OOP Class: A

Encapsulation

Encapsulation

Access modifiers (public, private, protected) Access modifiers in Object-Oriented Programming control the visibility and accessibility of class members (fields and methods), helping to enforce encapsulation and protect data integrity. Public Members declared as public are accessible from anywhere in the program They can be accessed

Inheritance

Inheritance

Concept of inheritance Inheritance is a core concept in Object-Oriented Programming that allows one class (called the child or subclass) to acquire the properties and behaviors (fields and methods) of another class (called the parent or superclass). It promotes code reuse, hierarchy, and a clear

Polymorphism

Polymorphism

Static (compile-time) vs dynamic (run-time) polymorphism Polymorphism is an essential concept in object-oriented programming that allows objects to be treated as instances of their parent class rather than their actual class. It enables a single interface to represent different types of behaviors. Polymorphism is categorized

Abstraction

Abstraction

Abstract classes and Methods Abstract classes and methods are core components of object-oriented programming used to enforce abstraction and design consistency. They define a base structure for other classes while deferring specific implementations to derived classes. What is an Abstract Class An abstract class cannot

Object Relationships and Design

Object Relationships and Design

“Has-a” vs “Is-a” Relationships In object-oriented programming, understanding the difference between “Has-a” and “Is-a” relationships is essential for designing effective class hierarchies and object models. These relationships define how classes and objects relate to each other and help clarify ownership, inheritance, and composition. Is-a Relationship

Advanced OOP Concepts

Advanced OOP Concepts

Static members and methods Static members and methods are class-level properties and functions that belong to the class itself rather than to any individual instance of the class. They are widely used in object-oriented programming to represent data or behavior that is common to all

Design Principles and Patterns

Design Principles and Patterns

SOLID principles SOLID is an acronym representing five core design principles in object-oriented programming that help developers create software that is easy to maintain, extend, and understand. These principles guide the design of classes and modules to improve code quality and promote best practices for

Practical Applications and Project

Practical Applications and Project

Applying OOP in real-world applications Object-Oriented Programming (OOP) provides a powerful way to structure software based on real-world entities. It uses concepts like classes, objects, encapsulation, inheritance, and polymorphism to build modular, scalable, and reusable applications. OOP is widely used across various domains such as
