Java 8 extending stream

Question

I\'m attempting to extend Java 8\'s Stream implementation.

I have this interface:

public interface StreamStuff extends Stream {

    St         


        

Answer 1

You are calling stream() on the Arrays class, which creates its own Stream implementation without any connection to yours. You'd have to produce the Stream yourself, or wrap a stream you obtained elsewhere, in order for something like this to work. Something like this:

int[] filtered = new StreamStuff(Arrays.stream(arr)).biggerThanFour().toArray();

However, in your case, why don't you just filter?

int[] filtered = Arrays.stream(arr).filter(i -> i > 4).toArray();
