Alex D Herbert commented on RNG-19:
-----------------------------------
Just trying some variations...
With a constructor:
{code:java}
Random random = ...;
UniformRandomProvider rng = new JDKRandomWrapper(random);
// Use Adaptor as per math4
UniformRandomProvider rng = new JDKRandomAdaptor(random);
{code}
Or a factory class without the Utils suffix:
{code:java}
Random random = ...;
UniformRandomProvider rng = Randoms.asUniformRandomProvider(random);
{code}
A factory class could be the entry point for conversions allowing the reverse:
{code:java}
UniformRandomProvider rng = ...;
Random random = Randoms.asRandom(rng);
{code}
This factory therefore allows to/from conversions between the Java random API
and the Commons RNG API.
The second method is helpful if you already have a UniformRandomProvider and
want to use it in for example:
{code:java}
Collections.shuffle(List<?>, Random)
{code}
Without adding the commons-sampling dependency for ListSampler::shuffle. I do
not know other JDK locations that require Random but 3rd party libraries would
likely use Random as the common API.

> Commons RNG could include a random number generator based on the output of
> /dev/random or /dev/urandom on Unix systems.
> Commons Crypto has an implementation that could be used as a starting point:
