Question

Is there a Java 8 stream operation that limits a (potentially infinite) Stream until the first element fails to match a predicate?

In Java 9 we can use

Answer 1

takeWhile is one of the functions provided by the protonpack library.

Stream infiniteInts = Stream.iterate(0, i -> i + 1);
Stream finiteInts = StreamUtils.takeWhile(infiniteInts, i -> i < 10);

assertThat(finiteInts.collect(Collectors.toList()),
           hasSize(10));
