Reactive and Asynchronous applications are growing in popularity, but what is the best way to build them? This course teaches you how to apply the latest concurrency techniques to develop state of the art Java applications. With the rise of Microservices and Service Oriented Architectures, asynchronous concurrency is now critical to day-to-day Java development.

We start off by reviewing the differences between asynchronous and synchronous programming. You then build upon this theory by refactoring a project using different modern concurrency techniques including promises using Java 8’s CompletableFuture, actors using Akka and reactive streams using RxJava. You’ll learn the good, the bad and the ugly between these approaches in terms of compositionality, testability and simplicity.
