On page 181 after the first bullet point list: "is" should be removed from the following sentence
"Think about your answer is before continuing."
On page 192 after the code example for allMatch(), anyMatch() and noneMatch() is the following explanation
anyMatch() returns true because two of the three elements match. allMatch() returns false because one doesn't match. noneMatch() also returns false because one matches.
The explanation for noneMatch() should be "also returns false because two match."
