A Functional Approach to Java: Augmenting Object-Oriented Java Code with Functional Principles 1st Edition

Java developers usually tackle the complexity of software development through object-oriented programming (OOP). But not every problem is a good match for OOP. The functional programming (FP) paradigm offers you another approach to solving problems, and Java provides easy-to-grasp FP tools such as lambda expressions and Streams. If you're interested in applying FP concepts to your Java code, this book is for you.Author Ben Weidig highlights different aspects of functional programming and shows you how to incorporate them into your code without going "fully functional." You'll learn how, when, and why to use FP concepts such as immutability and pure functions to write more concise, reasonable, and future-proof code. Many developers seek to expand their horizons by using OOP and FP together. It's no longer either-or; it's both.In this book, you will:Get a high-level overview of functional programming, including the types already available to Java developersExplore different FP concepts and learn how to use themLearn how to augment your code and use Java's new functional features in your daily work without going fully functionalDevelop a functional mindset and improve your programming skills regardless of language or paradigmAbout the AuthorBen Weidig is a self-taught software developer with almost two decades of experience in professional web, mobile, and systems programming in various languages. After learning the ropes of professional software development and project management at a clinical research organization, he became a self-employed software developer and is now co-director of a Java-based SaaS company.Besides sharing his expertise and experiences by writing articles about Java, functional programming, best practices, etc., he actively participates in Open-Source, either as a committer to established projects or releasing his own code.
