Urma Raoul-Gabriel, Fusco Mario, Mycroft Alan. Modern Java in Action: Lambdas, Streams, and functional-style programming

Nd edition. — Manning Publications Co, 2019. — 590 p. — ISBN: 978-1617293566.Modern applications take advantage of innovative designs, including microservices, reactive architectures, and streaming data. Modern Java features like lambdas, streams, and the long-awaited Java Module System makes implementing these designs significantly easier. It’s time to upgrade your skills and meet these challenges head-on!Modern Java in Action connects new features of the Java language with their practical applications. Using crystal-clear examples and careful attention to detail, this book respects your time. It will help you expand your existing knowledge of core Java as you master modern additions like the Streams API and the Java Module System, explore new approaches to concurrency, and learn how functional concepts can help you write code that’s easier to read and maintain.Fundamentals
