I don't understand how this book made it into print. It is filled with errors and awful advice. Almost ever few pages I want to set the book on fire.For example, let's look at the treatment of 'var' which was added in Java 10. The authors list all the different ways you can use var, including (cover your eyes):var var = 1:andpackage com.packt.cookbook.var:Why would you even suggest the first example or include the completely irrelevant second one?Next example: They discuss the Epsilon garbage collector (which is used for tuning and actually never collects garbage). They write an overly complex loop to allocate 4GB and they run it with a 4GB heap. When the allocations cause a memory error, they simply assert that is what they were expecting. That a reader unfamiliar with GC would want to know why allocating the full available space would cause an error apparently doesn't cross their minds. The reader is left to guess why they were expecting it. To top it off, as printed, the command-line options to run Epsilon contain a typo.Their discussion of Optional: "It was intended to help avoid the dreaded NullPointerException. But so far, the introduction of Optional helped to accomplish it only to a degree and mostly in the area of streams" They later repeat that it's not terribly useful when not used in streams. But they don't understand that *the whole intent* of Optional was precisely to be used in collections and streams. So the repeated complaints and general dismissal of Optional demonstrate ignorance rather than insight. Optional is a super-useful tool when working with streams.Even facts that would have been trivial to check are wrong (and this is a second edition!). For example, the first sentence on the back cover: "For more than three decades, Java has been at the forefront..." Java is about to celebrate its 25th birthday. More than three decades?The whole book is like this. I can't say that every page has a technical problem, but many sections do.Finally, there is the language. Neither author is a native speaker nor is the technical editor. And apparently no editor cleaned up the language after the authors turned in the drafts. There are many twisted sentences, others where subjects or verbs are missing, others where an expression is misused--all leading to frustrating lack of clarity at crucial points.Top to bottom, this book should be avoided.If you're looking for a good recipe book, I recommend Ken Kousen's "Modern Java Recipes" It doesn't go through Java 11, but everything in it is technically correct and the writing is clear.
