OOP Lecture 1Object-Oriented Programming (OOP): A Paradigm for Structured Software Design
In the realm of software development, Object-Oriented Programming (OOP) stands as a prominent
paradigm that guides the structuring and design of computer programs. At the heart of OOP lies the
concept of "objects," which serve as instances of classes. These classes act as blueprints or templates,
defining the shared properties and behaviors that characterize a particular type of object. An object, in
essence, represents a concrete manifestation of a class.
OOP embraces several fundamental concepts that shape its approach to software development:
Classes and Objects: Classes serve as blueprints for creating objects, encapsulating the attributes
(properties) and behaviors (methods) that define a particular type of object. Objects, as instances of
classes, embody these attributes and behaviors, allowing them to interact with each other and with the
wider program.
Encapsulation: Encapsulation promotes modularity by bundling data (attributes) and the methods that
operate on that data within a single unit or class. This approach shields the internal workings of an
object, exposing only the essential information to other parts of the program.
Abstraction: Abstraction emphasizes the core aspects of an object while concealing unnecessary details.
Programmers can create models that capture the essence of an object without delving into irrelevant
complexities, simplifying the development process.
Inheritance: Inheritance establishes a hierarchical relationship between classes, allowing subclasses to
inherit properties and methods from their parent classes. This mechanism promotes code reusability and
enables the creation of a structured class hierarchy.
Polymorphism: Polymorphism empowers objects of different classes to respond to the same method calls
in distinct ways. It facilitates the use of a single interface for entities of varying types, enhancing
flexibility and adaptability.
Object State and Behavior
Objects possess both state and behavior:
State: An object's state encompasses its attributes or properties, representing the data it holds.
Behavior: An object's behavior manifests through its methods or functions, defining the actions or
operations it can perform.
