More than a exam prep guide
I found this book better than the book "Java 11 Complete reference" because it addresses the topics in much detail with quizzes at the back.In each chapter, It covers the basics before jumping into the Java topic. For example, in Java I/O chapter, it first explains what a file system is, and then it starts to introduce java.io APIs for interacting with the file system. This is helpful especially for beginners who just started learning Java language. So, go for this book if you want to learn the basics to intermediate level knowledges of Java and don't get frightened by the title "Professional".

impresionante
Compre el libro como una guía para certificarme en Java 11, sin embargo este también trae consejos de programación de la vida real. Recomiendo el libro para todos aquellos que les gusta la programación en Java.

Just what I would need
This is a very large book, coming in at 1200 pages, but that is because it is the author's 815 and 816/817 books combined. The authors highlighted how to use the book to study for the 815, 816 or 817 exams, so it is easy to use, but if it's too much for you, they are also sold separately.I'm not finished with the book yet, but I like what I read so far. I started by looking at the security chapter. I really liked that Hacker Harry and Security Sienna characters were used to teach security. It made what could have been a dry chapter a lot more fun.If you are taking a Java certification, I highly recommend this combined book or the two separate ones.

Useful and thorough
A massive book, but well worth it to update your skills with the latest changes in Java 1q or to bone up on useful basics that you may have forgotten.

Libro molto esaustivo!
Comprato per l’esame 1Z0-819 (Java 11).È molto scorrevole e preciso, inoltre i test a fine capitolo sono qualcosa di meraviglioso.Per questo esame in particolare non esiste un libro preciso, perché sono sufficiente le versioni che già esistono. Come specificato da oracle e dal libro stesso, l’esame 819 sostituisce i vecchi 815, 816 e 817.
