Who This Book Is For

If you are a Java developer with object-oriented experience and want to use a functional programming approach in your applications, then this book is for you. All you need to get started is familiarity with basic Java object-oriented programming concepts.

What You Will Learn

• Use lambda expressions to simplyfy code
• Use function composition to achieve code fluency
• Apply streams to simply implementations and achieve parallelism
• Incorporate recursion to support an application's functionality
• Provide more robust implementations using Optionals
• Implement design patterns with less code
• Refactor object-oriented code to create a functional solution
• Use debugging and testing techniques specific to functional programs

In Detail

Functional programming is an increasingly popular technology that allows you to simplify many tasks that are often cumbersome and awkward using an object-oriented approach. It is important to understand this approach and know how and when to apply it. Functional programming requires a different mindset, but once mastered it can be very rewarding.

This book simplifies the learning process as a problem is described followed by its implementation using an object-oriented approach and then a solution is provided using appropriate functional programming techniques.

Writing succinct and maintainable code is facilitated by many functional programming techniques including lambda expressions and streams. In this book,l3+
