OCP Oracle Certified Professional Java SE 17 Developer Practice Tests: Exam 1Z0-829 1st Edition

I've been professionally developing Java for 25 years and yet this book still shows gaps in my understanding of the language and its core libraries. The questions are artfully constructed to cover the full breadth of the covered topics. I feel like some of the questions can be a little tricky, testing your ability to spot the trick more than your understanding of the material. However, I believe this is done intentionally as preparation for the certification exam, which apparently does the same thing. I intend to try the exam in the next few months, and I will feel well prepared for it after going through the mock exams in this book.Disclosure: I know one of this book's authors personally.
