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.
