RxJava is a Java VM implementation of ReactiveX (Reactive Extensions): a library for composing asynchronous and event-based programs by using observable sequences. It is a relatively new way of expressing and composing streams of data as well as asynchronous computations. In this two-day course, we will explore RxJava principles. This course provides fundamental concepts such as backpressure and hot vs. cold observables. We will also include training on creating observables and functional operators and understanding their behavior.

Course Summary

The course will enable the student to use advanced constructs such as subjects, handling and retrying on errors, and publishing events to the UI.
Developers and developer teams looking to learn to leverage RxJava.

Learning Style: 

Hands-on training is customized, instructor-led training with an in-depth presentation of a technology and its concepts, featuring such topics as Java, OOAD, and Open Source.

Hands On help

Seminars are highly-focused, lecture-heavy, half-day to multi-day learning events. Seminars are a great way to create an awareness level of knowledge for a large number of concepts, in a short period of time. Think wide (breadth) and thin (depth).

Seminar help

Workshops are instructor-led lab-intensives focused on the practical application of technologies through the facilitation of a project-related lab. Workshops are just the opposite of Seminars. They deliver the highest level of knowledge transfer of any format. Think wide (breadth) and deep (depth).
