Java 8 Streams - Timeout?

Question

I want to loop over a huge array and do a complicated set of instructions that takes a long time. However, if more than 30 seconds have passed, I want it to give up.

Answer 1

I would create a custom pool for that, something like:

ForkJoinPool forkJoinPool = new ForkJoinPool(1);
    try {
        forkJoinPool.submit(() ->
        IntStream.range(1, 1_000_000).filter(x -> x > 2).boxed().collect(Collectors.toList()))
                .get(30, TimeUnit.MILLISECONDS);
    } catch (TimeoutException e) {
        // job not done in your interval
    }
