In this lecture, we finally understand one of the most important concepts in modern Java, Lambdas and Functional Interfaces. If you’ve ever been confused about: What are lambdas in Java? What does “functions as first-class citizens” even mean? Why do we need functional interfaces? How does Comparator relate to lambdas? This video breaks everything down from first thought principles so you don’t just learn you deeply understand. What You’ll Learn: Why Java introduced Lambdas (problem with old approach) What it means to treat functions as first-class citizens Functional Interface concept (very important) Rules of functional interfaces Comparator Interface explained step-by-step Different ways to write lambda expressions Syntax variations (single-line vs multi-line) Creating your own functional interface Real-world understanding of behavior passing 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.
