Top 15 Java Stream and Functional Programming Interview Questions and Answers | by javinpaul | Javarevisited | Feb, 2025 | Medium
The java.util.stream.Stream class is one of the most useful class of Java 8 API. If I have to say that this is the class you would be using mostly while coding in Java 8 then it won't be an exaggeration. Since Stream class is integrated with Collection framework, you will end up using Streams for most of your day to day programming task in Java 8. It has several useful methods e.g. map() to convert one type of collection to other, flatMap to flatten a collection of collection, forEach to…

Understand the new Function<T, R> functional interface in Java 8. Tutorial explains how to use its four in-built methods - apply(), andThen(), compose() & identity() with detailed coded examples.
1️⃣ Basic Interface → Defines a contract 2️⃣ Default Method → Adds behavior without breaking old code 3️⃣ Functional Interface ⚡ → Enables lambda expressions 4️⃣ Multiple Interfaces → A class can implement multiple interfaces 5️⃣ Constants ⚠️ → Fields are public static final by default #Java #Programming #Code #Developer #OOP #Tech
A functional interface in Java is an interface that contains exactly one abstract method. They can be used as the assignment target for a lambda expression or method reference, enabling a more functional programming style.
