Title: I had never seen so many mistakes in a single book
Product review: I bought this book because of the chapter talking about Voyager. However, reading the book from cover to cover, I found many mistakes:- classes extending interface (instead of implementing) see pages 42, 168, 379- methods without return value; see pages 43, 62- code with compiler errors; see page 121- utilization of non-existing classes (see page 180: Invite)- Instantiation of abstract class (see page 200)- Unfinished code (see page 203, catch without type)- declaration of throws exception when those exceptions are never thrown (page 239)- error in the program logic (see page 285, where anExtension.actions should be used instead of anExtension.bundles)- strings not closed (see page 381).I reported these problems to the author and received no response. So, if you want to buy this book, forget about the code, because it won't compile...
