On page 133, we find, in the description for .replace() and .replaceAll() on Map interface:
These methods are similar to the Collection version except a key is involved.
Seemingly minor, but a major objective of this chapter is to remember which Interfaces and Classes covered on the exam contain which methods, so not so minor:
Collections helper class does have a replaceAll() method
Additionally, List interface has a .replaceAll() method, and has a way to replace things at an index called .set() (which you could forget and refer to as .replace(), ouch!!)
These are all things in the core of what I would want to make sure I won't be tripped up on at exam-time regarding Collection types/interfaces and method calls.
I would make that sentence more specific or remove it entirely, as it is too easy to "remember" methods on classes or interfaces where they don't exist as it is.
