I'm learning for the OCA exam right now, and I believe I spotted a typo on page 311, near the bottom of the page:
"If it is thrown, the first catch block takes care of it, making sure there no way to get to the second catch block."
Sounds like a word
is missing => "... making sure there is
no way to get to the second catch block."
I didn't see it in the errata on https://www.selikoff.net/java-oca-8-programmer-i-study-guide/
but maybe it has been reported already
