Functional Programming in Java, Second Edition: On page 27, after "Found 2 names"
On p.27, after “Found 2 names”, we read:
The filter() method returns an iterator just like the map() method does,
But it really returns a Stream for further processing, not an iterator.

You are correct that it returns a Stream but streams are internal iterators. Keeping the text as is.
Thank you.
