RANDOM.ORG is a true random number service that generates randomness via atmospheric noise. If you don't want to use a web browser to access the service, you can write your own client or download one of the clients listed below. All of the clients on this page access RANDOM.ORG through theHTTP Interface.
If you have written a client that you don't mind other people using,email us (preferably with instructions on how to use it), and we will put it on this page. You will of course get full credit.
Java Library
Author: Mars Gokturk
Date: 2014-06-13
Download:https://github.com/marsG/random.org-simpleclient
This simple java library is very easy to use. Just export it to your java project, and you can get random integers in base 2, 8, 10 and 16. It also enforces the valid input intervals for the minimum, maximum, and the amount of integers before executing the request on the server. This way, making unsupported requests are eliminated and the unproductive load on the server is decreased.
