Lambdas & Functional Interface Deep Dive | Method References & Composition | Java Full Course #38

In this lecture, we go deeper into Java Functional Programming by understanding Functional Interfaces in detail — right after learning Lambdas. This video covers: Different types of Functional Interfaces in Java Inbuilt interfaces like Predicate, Function, Consumer, Supplier How Method References simplify lambda expressions Deep understanding of Function Composition (andThen vs compose) Writing cleaner and more readable Java code using functional style If you’ve already learned Lambdas, this lecture will help you connect the dots and write production-level code. What you’ll learn in this video: What are Functional Interfaces (quick recap) Types of Functional Interfaces in Java Predicate, Function, Consumer, Supplier (with examples) Method References (Static, Instance, Constructor) Function Composition (andThen vs compose) Real-world use cases 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.
