Limit a stream by a predicate

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

Actually there are 2 ways to do it in Java 8 without any extra libraries or using Java 9.

If you want to print numbers from 2 to 20 on the console you can do this:

IntStream.iterate(2, (i) -> i + 2).peek(System.out::println).allMatch(i -> i < 20);

or

IntStream.iterate(2, (i) -> i + 2).peek(System.out::println).anyMatch(i -> i >= 20);

The output is in both cases:

2
4
6
8
10
12
14
16
18
20

No one mentioned anyMatch yet. This is the reason for this post.
