java - 生成无限双流

Question

我可以生成 Stream<Double>使用 generate .例如

Stream.generate(Math::random).limit(10).forEach(System.out::println);

如何生成无限随机 DoubleStream而不是 Stream<Double> ？

Answer 1

您可以使用 Random#doubles生成DoubleStream

Returns an effectively unlimited stream of pseudorandom double values, each between zero (inclusive) and one (exclusive). A pseudorandom double value is generated as if it's the result of calling the method nextDouble().

例如

new Random().doubles().limit(10).forEach(System.out::println);
