OOP in java

Object-Oriented Programming (OOP) in Java teaches you how to design software by organizing code into classes and objects that model real-world entities You’ll explore the four key principles of OOP: encapsulation, inheritance, polymorphism, and abstraction . Java’s strict class-based structure supports access control, method overriding, and interfaces for flexible and reusable code. The course covers constructors, method overloading, and the use of packages for modular design. Mastering OOP in Java is essential for creating scalable, maintainable, and efficient applications used across industries.
