Object-Oriented Programming (OOP) is a paradigm central to modern software development, emphasizing data encapsulation, inheritance, polymorphism, and abstraction. These principles foster modular, maintainable, and reusable code, exemplified in languages like Python and Java. OOP's approach allows for the creation of complex, scalable software systems, highlighting its significance in crafting robust applications.

OOP organizes software design around data and objects rather than functions and logic
Data field
An object is a data field with unique attributes and behavior
Encapsulation
Encapsulation protects the state of an object and requires all interaction to be performed through its methods
Encapsulation
Encapsulation allows for the hiding of internal state and interaction through methods
Inheritance
Inheritance creates new classes that share properties of existing classes, leading to a hierarchical classification
Polymorphism
Polymorphism allows for objects to be treated as instances of their parent class, enabling a single interface to represent different forms
Abstraction
Abstraction simplifies design by treating objects as black boxes and focusing on high-level operations
OOP principles contribute to the creation of robust, scalable, and maintainable software
Python
Python's clear and readable syntax and use of classes and objects make it well-suited for OOP
Java
Java's class-based approach, strong encapsulation, and robust interface system make it a popular choice for implementing complex software systems
OOP principles allow for the creation of modular and reusable code, making it easier to test and maintain over time
OOP principles such as inheritance and polymorphism enable systems to be more flexible and adaptable to changing requirements over time
00
OOP Principle: Encapsulation
Encapsulation shields object's internal state, allowing data access through methods, ensuring data integrity.
01
OOP Principle: Inheritance
Inheritance enables new objects to take on properties of existing ones, reducing repetitive code and fostering reuse.
02
OOP Principle: Polymorphism
Polymorphism permits objects to be treated as instances of their parent class, enabling multiple forms and dynamic method binding.
