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. #Java #Java8 #FunctionalInterface #LambdaExpression #Predicate #Consumer #Supplier #FunctionInterface #JavaTutorial #Programming #Coding #SpringBoot #BackendDevelopment #JavaDeveloper #DataEngineering #elevatemycode #elevate #mycode java predefined functional interface predefined functional interfaces in java 8 functional interfaces java 8 java 8 tutorial java lambda expressions predicate interface in java function interface in java consumer interface in java supplier interface in java unaryoperator interface java binaryoperator interface java java functional programming java 8 features java interview questions java stream api java coding tutorial java backend development functional interface examples java programming for beginners spring boot java tutorial java developer tutorial predicate function consumer supplier java functional programming concepts java 8 interview preparation core java tutorial advanced java concepts java programming language java developer interview questions lambda expression examples java stream examples
