public class JavaRandomIntUnseeded
extends AbstractRandomNumberGenerator<Integer>
implements RandomIntegerRangeGenerator<Integer>

Random generator that generates random integers using Java's java.util.Random class (unseeded).

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
 

-min-value <int> (property: minValue)
    The smallest number that could be generated.
    default: 1
 

-max-value <int> (property: maxValue)
    The largest number that could be generated.
    default: 1000
