Grokking the Java Interview: Prepare for Java interview by learning essential Core Java concepts and APIs (Grokking the Java and Spring Developer Interview Series) Paperback – Large Print, January 26, 2021

This isn't a good book for people new to Java to learn Java or use as a cheat sheet.However, it is very well designed for people who know Java and who need to brush up for the kind of quiz questions interviewers like to ask. First, it is brief. The quick question and answer format serves the concept of a refresher well. It isn't forcing a text book on the reader.The English in this book is poor. So much so, I had to reread sentences expressing straight forward ideas several times. This book could be vastly improved by sending it to a professional proofreader or even having a native English speaker with a background in Java proofread it.

A complete waste of money, you will gain a good understanding of common java concepts from free online resources rather than buying this book. As an experienced java developer, I can tell you the author either lacks a deep understanding of some of the concepts he is trying to explain or lacks words to better explain it. Disappointed
