Java Functional Programming :Play with Stream and Lambda with industry best practices

This Book will surely change your approach to Java Functional programming .This is one of the simplest Book for Java Functional Programming on the planet.

Before scripting any feature , I used to ask 4 questions to myself-What is this feature all about ? Why am I going for it ? Where can I use it in realtime ? And finally How can I implement it ? I have tried to simplify the concept of Streams and Lambda with help of sketch/images in-order to make it self explanatory.

In This Book I have covered industry trending concepts like Streams,Lambda,Method Reference, Functional Interfaces and other most commonly used Java features from Java 8 to Java 20.

This book is an insightful and practical guide that takes readers on a journey into the world of functional programming, exploring key concepts such as functional programming paradigms, streams, lambda expressions, and method references. This book is an essential resource for both beginners and experienced programmers looking to unlock the full potential of functional programming in their software development projects.

The book begins by demystifying functional programming, providing a clear understanding of its principles and benefits. It emphasizes the use of pure functions, immutability, and higher-order functions to write clean, maintainable, and efficient code.

A significant portion of the book is dedicated to streams, a powerful abstraction in functional programming. Readers will learn how to manipulate data using streams, applying operations like map, filter, and reduce to transform and process collections seamlessly. The book also explores the benefits of lazy evaluation and how it can improve performance in various scenarios.
Lambda expressions and another cornerstone of functional programming, are thoroughly explained with practical examples. Readers will discover how to create and use lambda functions to pass behavior as data, enabling more flexible and concise code.

Method references, an advanced feature in modern programming languages, are introduced as a tool to simplify code even further. Readers will learn how to leverage method references to express code more clearly and concisely, enhancing readability and maintainability.

Concepts of Streams and Lambda have been simplified in such a way that even a beginner can understand it. My main intention behind scripting this book is to architecting Java functional programming from o to very expert level to enable developers to write highly complex logic in simplest way possible.This Book is full of realtime best coding practices that we used to have in industry.

I have scripted the outcome of my 10 yrs of core software development experience in this Book and I hope this Book is going to help our developer community.
