36. Getting a legacy pseudo-random generator from new ones of JDK 17

A legacy pseudo-random generator such as Random, SecureRandom, or ThreadLocalRandom can delegate method calls to a RandomGenerator, passed as an argument to Random.from(), SecureRandom.from(), or ThreadLocalRandom.from(), as follows:

Random legacyRnd = Random.from(
   RandomGenerator.of("L128X256MixRandom"));
// or, like his
Random legacyRnd = Random.from(RandomGeneratorFactory.
   of("Xoroshiro128PlusPlus").create());
// or, like this
Random legacyRnd = Random.from(RandomGeneratorFactory
   .<RandomGenerator.SplittableGenerator>of(
      "L128X256MixRandom").create());

The from() methods are available starting with JDK 19. In the bundled code, you can see more examples.
