You're not alone.

At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don't want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns--the lessons learned by those who've faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on...something else. Something more challenging. Something more complex. Something more fun.

You want to learn about the patterns that matter--why to use them, when to use them, how to use them (and when NOT to use them). But you don't just want to see how patterns look in a book, you want to know how they look "in the wild". In their native environment. In other words, in real world applications. You also want to learn how patterns are used in the Java API, and how to exploit Java's built-in pattern support in your own code.

You want to learn the real OO design principles and why everything your boss told you about inheritance might be wrong (and what to do instead). You want to learn how those principles will help the next time you're up a creek without a design pattern.

Most importantly, you want to learn the "secret language" of Design Patterns so that you can hold your own with your co-worker (and impress cocktail party guests) when he casually mentions his stunningly clever use of Command, Facade, Proxy, and Factory in between sips of a martini. You'll easily counter with your deep understanding of why Singleton isn't as simple as it sounds, how the Factory is so often misunderstood, or on the real relationship between Decorator, Facade and Adapter.

With Head First Design Patterns, you'll avoid the embarrassment of thinking Decorator is something from the "Trading Spaces" show. Best of all, in a way that won't put you to sleep! We think your time is too important (and too short) to spend it struggling with academic texts.

If you've read a Head First book, you know what to expect--a visually rich format designed for the way your brain works. Using the latest research in neurobiology, cognitive science, and learning theory, Head First Design Patterns will load patterns into your brain in a way that sticks. In a way that lets you put them to work immediately. In a way that makes you better at solving software design problems, and better at speaking the language of patterns with others on your team.

Editorial Reviews

Review

This is a gimmicky book that actually works for once. It is an intelligent and well thought-out discussion of Java design patterns, and if you dont know what a design pattern is then this is an excellent way to find out. It is also an interested discussion of object-oriented design. I found that the authors often anticipated my reaction to their initial explanations and asked the questions that I would have asked had it been a lecture. - Mike James, VSJ, April 2005

About the Author

Eric Freeman is a computer scientist with a passion for media and software architectures and coauthor of Head First Design Patterns. He just wrapped up four years at a dream job-- directing internet broadband and wireless efforts at Disney--and is now back to writing, creating cool software, and hacking Java and Macs. Eric spent a lot of the '90s working on alternatives to the desktop metaphor with David Gelernter (and they're both still asking the question, "Why do I have to give a file a name?"). Based on this work, Eric landed a Ph.D. at Yale University in 1997. He also co-founded Mirror Worlds Technologies (now acquired) to create a commercial version of his thesis work, Lifestreams.

In a previous life, Eric built software for networks and supercomputers. You might know him from such books as JavaSpaces Principles Patterns and Practice. Eric has fond memories of implementing tuple-space systems on Thinking Machine CM-5s and creating some of the first internet information systems for NASA in the late 1980s.

When he's not writing text or code you'll find him spending more time tweaking than watching his home theater and trying to restore a circa 1980s Dragon's Lair video game. He also wouldn't mind moonlighting as an electronica DJ.

5.0 out of 5 stars Best way to learn Design Patterns November 10, 2004

By Jack D. Herrington VINE™ VOICE

Format:Paperback

At first I didn't understand how they would apply the Head First formula to design patterns. I'd read two head first before this one and I was impressed with those so I took a look and now, not only is it clear how they approached the topic, it's also clear to me that this is the best way to learn design patterns.

The Gang of Four book laid out the basics. Here is the pattern, here are some examples. The head first book goes a lot further. They show you good and bad examples of the pattern. They give solid reasoning behind the pattern. It's great.

There are times when I would look at a piece of code and have the author explain to me that it was based on one of the GoF patterns. I would come away thinking, if that's the pattern, then that pattern sucks. It's clear that patterns can be misapplied. So understanding the the how design patterns are applied, and how they are commonly applied wrongly, or to an extreme, is just as important as understanding the basic mechanics of the pattern itself.

The example code is in Java, but I think this is an ideal book for anyone passionate about patterns.

4.0 out of 5 stars Insufferably cute, but a very good intro nonetheless April 2, 2006

By David C. Veeneman

Format:Paperback

Unlike a lot of people, I don't care much for this book's 'irreverent' sytle. I think it masks some shortcoming in the examples it uses. But once you get past that, this is still the best introduction to object-oriented programming that I have read.

HFDP is not just about design patterns. It's a great introduction to object-oriented programming. The book does a great job of explaining the benefits of OOP over traditional procedural programming, and it explains OOP very well in terms of the most commonly used design patterns.

Now for the bad news. The examples are rather lightweight. They do a pretty good job of illustrating the concepts presented, but the code is in no way real-world. For example, if you are looking for which pattern to use to organize a UI (the 'Mediator', 'State', and 'Composite' patterns), with sample code, you won't find it here. The patterns are discussed, but they are used to create quacking ducks (really).

While that's by-and-large a shortcoming of the book, the code is so simple that non-Java programmers (like me) should have no problem using the book. The code samples are very basic, and should translate with little difficulty into .NET languages such as C# and VB.

One other item of note--this book contains a pretty good chapter on Model-View-Controller architecture, which seems to bedevil a lot of people. If you can get a handle on MVC, then you can pretty much do OOP.

In short, this is probably the book I would recommend as an intro to OOP. If you are under the age of 30, you will probably like the examples of quacking duck simulators and java-enabled gumball machines. For everybody else--it's worth looking past this book's insufferable cuteness if you are getting started in OOP.

5.0 out of 5 stars Irreverent, fun and <gasp> educational November 8, 2004

By Eric Wuehler

Format:Paperback

Usually when reading through a book or article on design patterns I'd have to occasionally stick myself in the eye with something just to make sure I was paying attention. Not with this book. Odd as it may sound, this book makes learning about design patterns fun.

The first thing you notice is the pages are not paragraph after paragraph of information. There isn't a single page that doesn't contain a doodle, a sidebar, a picture, or something different. While at times it can be a little distracting, it's in a good way (at least I don't have to poke myself with something sharp anymore).

The chapters cover various design patterns and along the way have exercises such as crossword puzzles or match games to test your understanding. The answers are also included at the end of the chapters - so you don't need to purchase a "Teacher's Edition" on the black market. =)

Other books on design patterns are saying, "Buehler... Buehler... Buehler..." while this book is on the float belting out "Shake it up, baby!"
