What I was worrying about is having a new API, for a behavior that could be obtained with an old one, but indeed this new API helps people not screw up as they would tend to if using the old one (and especially its default implementation), and it should be easy to make an adapter extending Random and have existing code use SplittableRandom through it. Also not extending Random saves memory and makes things faster (no method override). >Singling out a particular algorithm/method >for Gaussian stands mostly as an accident of history >in java.util.Random. Yes, that was just in case you were going to make SplittableRandom extend or at least imitate Random at some point, for convenience (like for nextDouble()). -Jeff
