4. Introduction to Object-Oriented Programming using Java
Object-Oriented Programming (OOP) is explored as a programming paradigm centered around classes and objects, emphasizing modular software design. Key OOP principles including encapsulation, inheritance, polymorphism, and abstraction are detailed within the context of Java. The chapter underlines Java's practicality and robustness as an object-oriented language ideal for various software applications.

What we have learnt
- Object-Oriented Programming (OOP) focuses on classes and objects for modular and maintainable software design.
- Java implements OOP principles effectively, offering features like platform independence and security.
- Understanding OOP concepts is essential for developing robust, scalable applications in Java.
Key Concepts
- -- ObjectOriented Programming (OOP)
- A programming paradigm that organizes software design around objects and classes to improve modularity and maintainability.
- -- Encapsulation
- The bundling of data (variables) and methods that operate on that data within a class, restricting direct access to some components.
- -- Inheritance
- A mechanism where one class can inherit properties and methods from another class, enabling code reuse.
- -- Polymorphism
- The ability of different classes to be treated as instances of the same class through method overriding and overloading.
- -- Abstraction
- The concept of hiding complex implementation details and exposing only the necessary features of an object or class.
