RxJava

Since its inception in 2012, RxJava has slowly gained in popularity for enabling reactive programming on Android. It is now deemed as the go-to and leading reactive library. Many companies have adopted the reactive way of programming, including Google, with its release of Android Architecture Components, which has many reactive elements in its design.

In this course, you will learn the fundamental principles of RxJava which will serve as a foundation for experienced Android developers who are new to the library and want to start integrating it into their apps.

Reactive Programming with RxJava

## Combining

Oftentimes we may find the need to combine several `Observable` streams into a single stream. Perhaps we have independent streams coming from multiple different sources and we would like to combine the results of these streams. Traditionally, in Java, this task is especially difficult, since synchronizing and blocking to wait for data coming from different threads of execution is error-prone and hard to debug. With RxJava, there are a few handy operators that allow us to combine several streams into a single unified stream.

### Merge

There are several overloaded flavors of the `.merge()` operator, all of which allow the merging of multiple `Observable` streams into a single stream.
