demo1

public static void demo1()

Prints the first size random numbers generated by the distribution.

main

public static void main(String[] args)

Benchmarks all subclasses

random

public static void random(int size,
                          boolean print,
                          double mean,
                          String generatorName)

Benchmarks all subclasses

Parameters:

size - the number of random numbers to be generated per subclass.

print - true prints each generated number, false does not print generated numbers (use this setting for benchmarking).

mean - the mean for distributions that require a mean.
