Totally Hard disagree on streams - I used parallel streams in my last Job nearly all the time. They are critical for cpu-intensive tasks involving large datasets. And they do involve just a single code change in the consuming code. Sequential to parallel processing can be done via one `.parallel`.

I always believed it was a major plus point for Java compared to other languages. I am even surprised to hear otherwise. How should parallel processing of streams work in your opinion, then ? Just saying it be unsupported would be laughable considering hardware today.

I would rate this feature 9/10. The fact that the author has rated it 1/10, shows he hasn't really worked on large, parallel processing of data - in Java anyways.
