A reasonable overview, but an old-style approach,
This review is from: Java Programming 24-Hour Trainer (Wrox Programmer to Programmer) (Paperback)
Customer review from the Amazon Vine Programme (What's this?)
Back in the 1990s many computer books took the reader through the syntax of a new language in a systematic way, introducing new concepts with each chapter, often building up a program incrementally on the way. As connectivity between computers increases the number of potential uses of a language has increased and programmers often become specialised in one area of design/programming rather than in one language.
This book takes the old approach, and shows an overview of a large number of local and network possibilities, all built up from Java. While there are many reasons to learn Java, it is unlikely that someone new to programming is going to want to progress from "Hello World" through all of the 37 lessons contained within - a more sensible approach would be to learn Java basics and then gain a deeper understanding of the technologies that interest you, and then apply your newly-gained language skills to them. Instead this book takes a lighting tour (for example, 9 pages covering Hibernate) of various aspects of the technology, but without getting deeper in any of them. As a reader you will know the technologies exist, but will probably not understand why any one technology is worth looking at or not.
There's nothing intrinsically wrong with the book, and it teaches the basics of Java well in the first 17 lessons, but it's difficult to be sure that the target audience exists anymore. If you're interested in learning Java then the first half of the book will help, but it might be worth skipping the second half until you have some understanding of why it might be useful to look at any one technology in particular. Developers who are just starting with one of the technologies in the second half of the book will find the relevant chapter useful for a short time, but quickly want more details. The practice-interview questions at the end are rather good, though it's not worth buying the book for them alone!
