Reactive programming is a programming paradigm that is different from what most developers are used to. It is really powerful and flexible. Understanding it properly and using it wisely can bring a lot of benefits to your applications.

There is immense interest in Reactive programming right now. While most people can start with it quickly, it’s not always obvious what the differences are between some reactive concepts. RxJava 2.0 is the library we’ll use to put all these concepts into practice, and it will help us develop a robust and well-structured application.

Akka is quite popular as well, however, it’s not always obvious how its artefacts match the Reactive Stream’s API specification. Aside from the theoretical foundation that Reactive programming needs, we will develop a real-life reactive RESTful web application step by step using Spring, Jersey, RxJava 2.0, and Java 9. Throughthis, you’ll get hands-on with all the concepts so you’llbe ready to use Reactive programming in your applications.
