Head First Design Patterns

“I received the book yesterday and started to read it on the way home... and I couldn’t stop. I took it to the

gym and I expect people saw me smiling a lot while I was exercising and reading. This is tres ‘cool’. It is

fun but they cover a lot of ground and they are right to the point. I’m really impressed.”

— Erich Gamma, IBM Distinguished Engineer,

and co-author of Design Patterns

“‘Head First Design Patterns’ manages to mix fun, belly-laughs, insight, technical depth and great practical

advice in one entertaining and thought provoking read. Whether you are new to design patterns, or have

and founder of the Hillside Group

“This book is close to perfect, because of the way it combines expertise and readability. It speaks with

authority and it reads beautifully. It’s one of the very few software books I’ve ever read that strikes me as

indispensable. (I’d put maybe 10 books in this category, at the outside.)”

— David Gelernter, Professor of Computer Science,

Yale University and author of “Mirror Worlds” and “Machine Beauty”

“A Nose Dive into the realm of patterns, a land where complex things become simple, but where simple

things can also become complex. I can think of no better tour guides than the Freemans.”

— Miko Matsumura, Industry Analyst, The Middleware Company

Former Chief Java Evangelist, Sun Microsystems

including “C++ for Java Programmers”

“Jerry Rice runs patterns better than any receiver in the NFL, but the Freemans have out run him.

Seriously...this is one of the funniest and smartest books on software design I’ve ever read.”

— Aaron LaBerge, VP Technology, ESPN.com

Head First Design Patterns

“Great code design is, first and foremost, great information design. A code designer is teaching a com-

puter how to do something, and it is no surprise that a great teacher of computers should turn out to be

a great teacher of programmers. This book’s admirable clarity, humor and substantial doses of clever

make it the sort of book that helps even non-programmers think well about problem-solving.”

— Cory Doctorow, co-editor of Boing Boing

A storyteller? An architect or a builder? A pitch person or a visionary? Can an individual indeed be in

part all of these? And most importantly, who the %$!#&* cares?

It has been said that the “designed by” credit in interactive entertainment is akin to the “directed by”

credit in filmmaking, which in fact allows it to share DNA with perhaps the single most controversial,

overstated, and too often entirely lacking in humility credit grab ever propagated on commercial art.

Good company, eh? Yet if Design is Life, then perhaps it is time we spent some quality cycles thinking

about what it is.

Eric and Elisabeth Freeman have intrepidly volunteered to look behind the code curtain for us in

“Head First Design Patterns.” I’m not sure either of them cares all that much about the PlayStation

or X-Box, nor should they. Yet they do address the notion of design at a significantly honest level such

practical development strategies—gets my brain going without having to slog through a bunch of tired,

stale professor-speak.”

Member of the MIT TR100

“This book combines good humors, great examples, and in-depth knowledge of Design Patterns in

such a way that makes learning fun. Being in the entertainment technology industry, I am intrigued

by the Hollywood Principle and the home theater Facade Pattern, to name a few. The understanding

of Design Patterns not only helps us create reusable and maintainable quality software, but also helps

sharpen our problem-solving skills across all problem domains. This book is a must read for all com-

puter professionals and students.”

and remember. Not just loads of pictures: pictures of humans, which tend to interest other humans.

Surprises everywhere. Stories, because humans love narrative. (Stories about things like pizza and

chocolate. Need we say more?) Plus, it’s darned funny.

It also covers an enormous swath of concepts and techniques, including nearly all the patterns you’ll

use most (observer, decorator, factory, singleton, command, adapter, façade, template method, iterator,

composite, state, proxy). Read it, and those won’t be ‘just words’: they’ll be memories that tickle you,

and tools you own.”

— Bill Camarda, READ ONLY

“After using Head First Java to teach our freshman how to start programming, I was eagerly waiting to

see the next book in the series. Head First Design Patterns is that book and I am delighted. I am sure

this book makes learning about design patterns fun.

While other books on design patterns are saying, ‘Buehler... Buehler... Buehler...’ this book is on the float

belting out ‘Shake it up, baby!’”

— Eric Wuehler

“I literally love this book. In fact, I kissed this book in front of my wife.”

— Satish Kumar

“Java technology is everywhere—in mobile phones, cars, cameras, printers, games, PDAs, ATMs, smart

cards, gas pumps, sports stadiums, medical devices, Web cams, servers, you name it. If you develop

software and haven’t learned Java, it’s definitely time to dive in—Head First.”
