Interface in Java | Part-1 | What Is Interface? | Blueprint & Standardization | Hindi

Welcome back to CodeHunt’s Core Java Tutorial in Hindi!
In today’s session, we begin one of the MOST important topics for interviews and real-time development — Interface in Java (Part-1).

Interfaces are the backbone of Abstraction, Loose Coupling, and Standardization in Java, and this video lays a strong foundation for everything that comes later.

🎯 What You’ll Learn in This Video (Part-1)
✅ 1. What Is an Interface?

– Simple definition
– Why interfaces were introduced in Java
– Role of interfaces in achieving abstraction
– How interfaces define a blueprint for classes

✅ 2. How to Create an Interface

– Syntax of interface creation
– Declaring methods inside an interface
– Difference between class and interface structure

✅ 3. Interface = Blueprint + Standardization

– Why interface is called a blueprint
– How interface enforces a standard across multiple classes
– Real-life examples of standardization (remote, USB, driver API, etc.)

✅ 4. You Cannot Create Objects of an Interface

– Explanation with simple example
– Reason: incomplete methods
– How objects are created using implementation classes

✅ 5. Interface Methods Are Always Public

– Why methods are public
– Default behavior of method modifiers
– How Java ensures accessibility through interfaces

🧠 By the End of This Session

You will clearly understand:

✔ What an interface is
✔ Why it is considered a blueprint
✔ What standardization means in OOP
✔ Why interface objects cannot be created
✔ Why all interface methods are public by default

This is the FIRST step toward mastering advanced OOP concepts and frameworks like Spring, Hibernate, and Microservices, where interfaces are used everywhere.
