All you need to get started is familiarity with basic Java object-oriented programming concepts.What You Will LearnUse lambda expressions to simplyfy codeUse function composition to achieve code fluencyApply streams to simply implementations and achieve parallelismIncorporate recursion to support an application’s functionalityProvide more robust implementations using OptionalsImplement design patterns with less codeRefactor object-oriented code to create a functional solutionUse 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.

Due to copyright restrictions, this eBook may not contain all of the images available in the print edition. It was the summer Coltrane died, the summer of love and riots, and the summer when a chance encounter in Brooklyn led two young people on a path of art, devotion, and initiation. Patti Smith would evolve as a poet and performer, and Robert Mapplethorpe would direct his highly provocative style toward photography. Bound in innocence and enthusiasm, they traversed the city from Coney Island to Forty-second Street, and eventually to the celebrated round table of Max's Kansas City, where the Andy Warhol contingent held court. In 1969, the pair set up camp at the Hotel Chelsea and soon entered a community of the famous and infamous the influential artists of the day and the colorful fringe. It was a time of heightened awareness, when the worlds of poetry, rock and roll, art, and sexual politics were colliding and exploding. In this milieu, two kids made a pact to take care of each other. Scrappy, romantic, committed to create, and fueled by their mutual dreams and drives, they would prod and provide for one another during the hungry years. Just Kids begins as a love story and ends as an elegy. It serves as a salute to New York City during the late sixties and seventies and to its rich and poor, its hustlers and hellions. A true fable, it is a portrait of two young artists' ascent, a prelude to fame.
