p54, in the second last paragraph, I think that in "The Walk interface neither extends any functional interface classes nor ..." the word "classes" should be removed.

Claude,
Welcome to CodeRanch! Which book is this? There are a few study guides with very similar names. (Who was the author or publisher?)

Jeanne,

Very fast answer! Sorry for not being specific: I am studying with this - very good - book:
OCP Oracle Certified Professional Java SE 8 Programmer II STUDY GUIDE
EXAM 1Z0-809
Jeanne Boyarsky and Scott Selikoff
SYBEX A Wiley Brand
Copyright 2016
ISBN: 978-1-119-06790-0

and the supposed typo is in Chapter 2 - Design Patterns and Principles,
Defining a Functional Interface,
p. 54,
second line of the second to last paragraph

Claude,
Ah, I see it now. I agree that it should have said "functional interfaces" to be more succinct. Technically an interface is a type of class/in a class file. But that's not that point.

I've added it to our private list of things that could be clearer for the next edition.
