I am having trouble understanding the Stream
interface in Java 8, especially where it has to do with the Spliterator
and Collector
interfaces. My problem is that I simply can't understand Spliterator
and the Collector
interfaces yet, and as a result, the Stream
interface is still somewhat obscure to me.
What exactly is a Spliterator
and a Collector
, and how can I use them? If I am willing to write my own Spliterator
or Collector
(and probably my own Stream
in that process), what should I do and not do?
I read some examples scattered around the web, but since everything here is still new and subject to changes, examples and tutorials are still very sparse.
