RxJava

RxJava is the Reactive Extensions library for the JVM. RxJava makes it easy to composing asynchronous and event-based programs using observable sequences of data in Java applications. This course takes a detailed look at the RxJava API and explores various patterns and techniques to ensure you make the most of concurrency, parallelism, and data throttling.
