Learn Java 8 Predefined Functional Interfaces | Predicate, Function, Consumer, Supplier in Java
In this Java 8 tutorial, you will learn about Predefined Functional Interfaces with practical coding examples. 🚀
Java 8 introduced several built-in functional interfaces in the java.util.function package that make coding easier and more expressive.
🔹 What you will learn in this video:
✔️ What are Functional Interfaces in Java 8
✔️ Overview of the java.util.function package
✔️ Predicate – test a condition and return boolean
✔️ Function – take input and return output
✔️ Consumer – accept input and perform an action
✔️ Supplier – provide results without input
✔️ Use cases of functional interfaces in Streams API and Lambda Expressions
This tutorial is beginner-friendly and helpful for Java developers, backend engineers, and students preparing for interviews.
👉 By the end of this video, you will have a clear understanding of how to use Predefined Functional Interfaces in real-world Java projects.
