public class JavaRandomDouble
extends AbstractSeededRandomNumberGenerator<Double>

Random generator that generates random doubles (0-1) using Java's java.util.Random class.

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

-seed <long> (property: seed)
    The seed value for the random number generator.
    default: 1
