My suggestion is to add two methods to ArrayUtils in commons-lang for each primitive type and Object (and maybe a couple more if we want to shuffle only a subset of the array): ArraysUtils.shuffle(Object[] array) ArraysUtils.shuffle(Object[] array, java.util.Random rnd) And if we want to shuffle with a random generator from commons-rng, we simply convert the UniformRandomProvider into a java.util.Random using the adapter: RandomProvider rng = RandomSource.create(...); ArraysUtils.shuffle(array, new JDKRandomAdapter(rng)); or RandomProvider rng = RandomSource.create(...); ArraysUtils.shuffle(array, rng.asRandom()); Emmanuel Bourg --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
