Ebook: Scala for Java Developers

Build reactive, scalable applications and integrate Java code with the power of Scala

Overview

• Learn the syntax interactively to smoothly transition to Scala by reusing your Java code
• Leverage the full power of modern web programming by building scalable and reactive applications
• Easy to follow instructions and real world examples to help you integrate java code and tackle big data challenges

In Detail

Scala for Java Developers is a step-by-step guide full of easy-to-follow code taken from real-world examples explaining the migration and integration of Scala in a Java project.

With this book, you will first get comfortable with the Scala syntax and its Java-like ecosystem, and then dive into new ways of building reactive web apps using the Typesafe stack including the actor-based Akka framework, the Play web framework, and the emerging Slick framework for persistence. The book will then teach you how to review useful tools for unit, integration, and functional testing; demonstrate how integrating with external systems applies to the Scala world and what its benefits are.

From learning the Scala syntax interactively to writing modern, scalable, reactive applications, this book will help you to take your skills to the next level by solving complex problems in a concise and maintainable way.
