Create robust and maintainable Java applications using the functional
style of programming About This Book • Explore how you can blend
object-oriented and functional programming styles in Java • Use
lambda expressions to write flexible and succinct code • A tutorial
that strengthens your fundamentals in functional programming
techniques to enhance your applications 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, you will see numerous examples
of how these techniques can be applied starting with an introduction
to lambda expressions. Next, you will see how they can replace older
approaches and be combined to achieve surprisingly elegant solutions
to problems. This is followed by the investigation of related concepts
such as the Optional class and monads, which offer an additional
approach to handle problems. Design patterns have been instrumental in
solving common problems. You will learn how these are enhanced with
functional techniques. To transition from an object-oriented approach
to a functional one, it is useful to have IDE support. IDE tools to
refactor, debug, and test functional programs are demonstrated through
the chapters. The end of the book brings together many of these
functional programming techniques to create a more comprehensive
application. You will find this book a very useful resource to learn
and apply functional programming techniques in Java. Style and
approach In this tutorial, each chapter starts with an introduction to
the terms and concepts covered in that chapter. It quickly progresses
to contrast an object-oriented approach with a functional approach
using numerous code examples.
