RxJava on Github
a library for composing asynchronous and event-based programs by using observable sequences.
A library running on the Java VM that uses observable sequences to compose asynchronous, event-based programs. (Excuse my limited English)

Why did we choose RXJava compared to other technologies??
Observable and Subscriber can do anything:
1.Observable can be a network request or Subscriber to display the request result;
2.Observable can be a database query, Subscriber to display query results;
Observable can be button click event or Subscriber to respond to click event.
4.Observable can be a load and parse of large picture files, Subscriber can display the parsed picture.
This article, the first in a series of articles, shows you the API for creating an Observable without further ado.
Create:
just:
from:
Just vs. FROM: Just shoots the array once as an entire object, whereas FROM shoots each object in the array once, meaning multiple shoots.
Defer:
Defer allows you to create an Observable until an observer subscribes, and to create a new Observable for each observer
Interval:
Interval creates an Observable that emits integer sequences at fixed intervals
timer:
The Timer creates an Observable that emits a special value after a given delay
range:
Range creates an Observable that emits a particular sequence of integers, an ordered sequence of integers in a range, where you can specify the start and length of the range
repeat:
Repeat creates an Observable that emits a particular data multiple times
Conclusion:
The above methods provide basic examples of RxJava API for creating Observable objects.
Note: I will add the GitHub source address at the end of this series, so stay tuned…
