    Jafaran

    Fast and more random implementations of java.util.Random.

    Jafaran (Java Fast Random) provides fast, and for some more random, implementations of java.util.Random, with additional nextXXX() methods, and methods to retrieve and restore state. The names of implementations contain "Conc" (for concurrent) if they are thread-safe and non-blocking, or "Seq" (for sequential) if they are not thread-safe. Also provides an implementation of Ziggurat algorithm (based on J. A. Doornik paper, 2005), used by nextGaussian() methods of the provided implementations. Requires Java 5 or later. Also available on github since 2015/12/13: https://github.com/jeffhain/jafaran Principal classes: - Implementations using Mersenne-Twister algorithm (good pseudo-randomness): MTSyncRNG MTSeqRNG - Implementations using Marsaglia Xor-Shift (fast): MXSIntSeqRNG (32 bits) MXSLongSeqRNG (64 bits) (nextLong() faster, larger period) - Ziggurat: Random-based implementation of Ziggurat algorithm.

    Java Random Numbers - Random.Org API

    Offers Random numbers API for your programs written in Java.

    Very lightweight and easy to use library that allows you to generate truly random numbers by means of Random.Org service. Library offers optimized algorithms for obtaining single random number or more random numbers at once, sequences of numbers, random strings etc. Also allows you to check quota. It provides algorithm to generate unspecified number of random numbers of certain total value. This algorithm still keeps server load low by sending as large requests as possible, yet all integers are truly random. ******************************************* Current version 1.5 is considered as STABLE version. All methods and whole class are documented via Javadoc. Credit goes to http://www.random.org
