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

About this book

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 youre 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." Youll 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. Its no longer either-or; its both. In this book you will: Get a high-level overview of functional programming including the types already available to Java developers Explore different FP concepts and learn how to use them Learn how to augment your code and use Javas new functional features in your daily work without going fully functional Develop a functional mindset and improve your programming skills regardless of language or paradigm
