In this video, we begin the most important concept in Java — Object Oriented Programming (OOP). Before writing advanced Java code, you must clearly understand how OOP works, why traditional programming had limitations, and how Java models the real world using classes and objects. In this complete foundational lecture, we cover: Traditional Programming vs Object-Oriented Programming Problems with the procedural approach Representing the real world in code What are Classes? User-defined data types Creating Objects Compile-time vs Runtime concepts Characteristics of Objects Naming conventions in Java Representing behaviors Non-physical objects in programming Writing your first Class & Object Understanding the role of the Main class This lecture builds the base for everything ahead : Abstraction, Inheritance, Polymorphism, Encapsulation, Design Patterns, and System Design. Why Learn Java? Java is one of the most powerful and widely used programming languages in the world. It is used in: Backend development Enterprise applications Android development Banking systems Large-scale distributed systems If you want to master Data Structures, Spring Boot, Microservices, or System Design, Java fundamentals are essential.
