public interface RandomNumberGenerator extends Seedable
A (pseudo) random number generator is an algorithm designed to generate a sequence of numbers that lack any pattern. However, it is very important to know that the sequence is not random at all and that it is completely determined by a relatively small set of initial values. Knowing the generation algorithm and the states can predict the next value, as the values are generated in a deterministic way. By default, an implementation ofRandomNumberGenerator
is not thread-safe, and thus should not be shared among multiple threads. If aRandomNumberGenerator
instance is used in a multi-threaded program, for example, useRandomNumberGenerator rng = RandomNumberGenerators.synchronizedRNG(new Gaussian());
