Software development today is embracing functional programming
(FP), whether it's for writing concurrent programs or for managing Big Data. Where does that leave Java
developers? This concise book offers a pragmatic, approachable introduction to FP for Java
developers or anyone who uses an object-oriented language.
Dean Wampler, Java
expert and author of Programming Scala
(O'Reilly), shows you how to apply FP principles such as immutability, avoidance of side-effects, and higher-order functions to your Java
code. Each chapter provides exercises to help you practice what you've learned. Once you grasp the benefits of functional programming, you'll discover that it improves all of the code you write.
