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

Java developers often use object-oriented programming (OOP) to handle complexity. However, functional programming (FP) provides an alternative approach. This book demonstrates how to incorporate FP concepts into Java code, such as immutability and pure functions, to write more concise, reasonable, and future-proof code. It covers a functional approach and real-world problems, patterns, and recipes.

Java developers often employ object-oriented programming (OOP) to address the complexity of software development. However, it is important to recognize that not every problem is ideally suited for OOP. Functional programming (FP) presents an alternative approach to problem-solving, and Java offers convenient FP tools like lambdas and streams. If you are interested in incorporating FP concepts into your Java code, this book is designed for you. Author Ben Weidig delves into various aspects of functional programming and demonstrates how to seamlessly integrate them into your code without fully adopting a functional programming style. You will learn when, why, and how to employ FP concepts such as immutability and pure functions to create more concise, reasonable, and future-proof code. Many developers aim to broaden their skill sets by combining OOP and FP. It is no longer a case of choosing between the two; rather, they can be effectively combined to achieve optimal results.

This book is divided into two parts:

A Functional Approach: In this section, you will gain a high-level understanding of functional programming, including the types already available to Java developers. You will then explore different FP concepts and learn how to apply them effectively.

Real-World Problems, Patterns, and Recipes: In this part, you will apply the knowledge gained in the first section to real-world problems you might encounter in your daily work. You will learn how to apply FP techniques to solve these problems efficiently and effectively.

By combining the power of OOP and FP, you can develop software that is more modular, flexible, and scalable. This book will provide you with the tools and knowledge you need to embrace FP in your Java development journey and create innovative and efficient solutions to complex problems.
