What theyre saying about Head First

Amazon named Head First Java a Top Ten Editors Choice for Computer Books of 2003 (first edition)

Software Development Magazine named Head First Java a finalist for the 14th Annual Jolt Cola/Product Excellence Awards

Kathy and Berts Head First Java transforms the printed page into the closest thing to a GUI youve ever seen. In a wry, hip manner, the authors make learning Java an engaging whatre they gonna do next? experience.

Warren Keuffel, Software Development Magazine

...the only way to decide the worth of a tutorial is to decide how well it teaches. Head First Java excels at teaching. OK, I thought it was silly... then I realized that I was thoroughly learning the topics as I went through the book.

The style of Head First Java made learning, well, easier.

slashdot (honestpucks review)

Beyond the engaging style that drags you forward from know-nothing into exalted Java warrior status, Head First Java covers a huge amount of practical matters that other texts leave as the dreaded exercise for the reader... Its clever, wry, hip and practicalthere arent a lot of textbooks that can make that claim and live up to it while also teaching you about object serialization and network launch protocols.

Dr. Dan Russell, Director of User Sciences and Experience Research IBM Almaden Research Center (and teaches Artificial Intelligence at Stanford University)

Its fast, irreverent, fun, and engaging. Be carefulyou might actually learn something!

Ken Arnold, former Senior Engineer at Sun Microsystems Co-author (with James Gosling, creator of Java), The Java Programming Language

Java technology is everywhereIf you develop software and havent learned Java, its definitely time to dive inHead First.

Scott McNealy, Sun Microsystems Chairman, President and CEO

Head First Java is like Monty Python meets the gang of four... the text is broken up so well by puzzles and stories, quizzes and examples, that you cover ground like no computer book before.

Douglas Rowe, Columbia Java Users Group

If you want to learn Java, look no further: welcome to the first GUI-based technical book! This perfectly-executed, ground-breaking format delivers benefits other Java texts simply cant... Prepare yourself for a truly remarkable ride through Java land.

Neil R. Bauman, Captain & CEO, Geek Cruises (www.GeekCruises.com)

If youre relatively new to programming and you are interested in Java, heres your book...Covering everything from objects to creating graphical user interfaces (GUI), exception (error) handling to networking (sockets) and multithreading, even packaging up your pile of classes into one installation file, this book is quite complete...If you like the style...Im certain youll love the book and, like me, hope that the Head First series will expand to many other subjects!

LinuxQuestions.org

I was ADDICTED to the books short stories, annotated code, mock interviews, and brain exercises.

Michael Yuan, author, Enterprise J2ME

Head First Java... gives new meaning to their marketing phrase `Theres an O Reilly for that.` I picked this up because several others I respect had described it in terms like revolutionary and a described a radically different approach to the textbook. They were (are) right... In typical OReilly fashion, theyve taken a scientific and well considered approach. The result is funny, irreverent, topical, interactive, and brilliant...Reading this book is like sitting in the speakers lounge at a view conference, learning from and laughing with peers... If you want to UNDERSTAND Java, go buy this book.

Andrew Pollack, www.thenorth.com

If anyone in the world is familiar with the concept of Head First, it would be me. This book is so good, Id marry it on TV!

Rick Rockwell, Comedian The original FOX Television Who Wants to Marry a Millionaire groom

This stuff is so fricking good it makes me wanna WEEP! Im stunned.

Floyd Jones, Senior Technical Writer/Poolboy, BEA

A few days ago I received my copy of Head First Java by Kathy Sierra and Bert Bates. Im only part way through the book, but whats amazed me is that even in my sleep-deprived state that first evening, I found myself thinking, OK, just one more page, then Ill go to bed.
