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 experien

Easily the best introduction to design patterns I've seen. If you're new to object-oriented design or new to design patterns, this is the first (but definitely not the only) book you should buy.

Computer books are so often textbooks written in the high-falutin' language of hooded academics. There's nothing wrong with that, but such language is next to useless for the uninitiated. O'Reilly's Head First series breaks the textbook mold with verve. I find Design Patterns to be, by far, the most succe

I fell in love with this book as soon as it got into my hands. I was struck by how it is written and organized.

Unlike all other books, it follows a very exciting comic like writing style. The book is full of humor and it takes the reader step by step towards a solid understanding of what software design patterns are. I clearly got the feeling that the authors are trying hard to make "me" understand rather than just presenting some information on the topic.

I recommend this book for any one with a

This is one of the best technical books I've ever read. It changed my world as a programmer and what I thought was a good technical book. The topic is very important for any developer that works with object-oriented programming (OOP) and the book presents a complicated topic in a fun, readable way (with lots of pictures!).

I highly recommend this book to any developer, no matter how experienced, and especially those who struggle getting through the long, boring technical books out there and are l

I tried to start my design pattern education with the classic GOF's book. Well, it ended with the first few pages and became a coffee cup coaster. Sacrilege, I know, but I have to be honest. I also tried another Head First book, on another topic and while okay, it just didn't speak to me. I only tried this book after a Microsoft Partner I respected recommended it. Wow. It is probably one of the best introductory technical books I've read in my 20 years of programming. The whimsical and technical ...more

I am going to give this book a review even though I am only part of the way through, in part because I think it belongs on my highly-recommend list. The original GOF patterns book is good, is a classic, and should probably be on your bookshelf. This however is much better book on patterns for the typical developer, the content is more accessible and is more up-to-date. Moreover this book has a great attitude and is a lot of fun to read.

Apesar de não ser um livro tão recente, é um excelente livro e com muita interação com o leitor. Aborda os principais padrões de projetos com exemplos bem didáticos e práticos, porém “fictícios” não tão reais para o dia-a-dia de trabalho, mesmo assim é de grande utilidade.
Pude conhecer com mais detalhes alguns padrões projetos e seus princípios, porém alguns padrões foram rapidamente explicados, ficando à dever do leitor a fazer suas próprias pesquisas de exemplos práticos.

Head First Design Patterns is a great way to get a good overview (and some meat) about design patterns. This will interest programmers and computer scientists the most, but as you learn near the end of the book, design pattern were first created by an architect! So if you're interested is solving problems or how to break apart a problem into pieces that are more easily solved, this book may interest you.

If you're like me -- a software developer who's been around a while -- you will have noticed

Must read even for experienced programmers. Explained in the very practical and attractive way.

Someone has already solved your problems.

Favor composition over inheritance.

How many design meetings have you been in that quickly degrade into implementation details?

Knowing the OO basics does not make you a good OO designer.

Remember, code should be closed (to change) like the lotus flower in the evening, yet open (to extension) like the lotus flower in the morning.

If you want to get up to speed on object oriented programming techniques, but your mind can't handle pages & pages of dense technical prose, then this is for you!

Written & laid out in a comic book style similar to the "... For Beginners" books (Marx For Beginners, Zen For Beginners etc, see the technical explanations are reassuringly well spaced out between brain-friendly pictures and diagrams.

The text itself is in the form of a (rather goofy) story abo

great intro to patterns for noobs like me.
Much more readable than the Gang of Four book.

A bit outdated - lacking functional design patterns and over relies on mutability, especially in the State Pattern.
Everything in the Composite Pattern chapter could be implemented more cleanly and elegantly using the Visitor Pattern. Proxy pattern is pretty outdated too. Then again, the gang of four book is pretty old too at this point.

Code uses pretty old version of Java - Doesn't have enums or generics, to

This is an outstanding book and is actually quite fun to read!

I don't personally own it but we had a copy in out restroom at work and I'd read through it periodically. I read the classic gang of four patterns book prior to this one and I must say that this one is probably better of the two for most people, especially more inexperienced developers. The focus of this book is less on a pattern language and more on how to use object oriented languages to solve real problems and while not building a

Meh, this was fine, but not as tight as Head First SQL - The Head First formula doesn't scale super-well to a book of this size, and the segments are too disconnected. It's still good at giving you the gist of the concept, but the topic of design patterns seems to lend itself to a catalog format that Head First doesn't handle very well. Got me thinking, but I won't be ready to talk intelligently about patterns until I get a more traditional book.

Actually, I just saw that this is only 31 pages lo

I'd always been a bit worried about the head first series - they look a bit like astrophysics for idiots - but having read the patterns book I'm impressed, I feel like a lot more has sunk in that the last patters book I read (C# Design Patterns, which was over-obsessed with swim meets and felt like the author had been forced to use C# at gunpoint - I wouldn't recommend it). I also liked getting to do a crossword puzzle at the end of most chapters. It's Java oriented but only gets deeply into Jav ...more

اما اگه در حین پروژه به مشکل بر بخورین بعد برین سراغ الگوها تا مشکلتون رو حل کنند، دیگه ملکهٔ ذهنتون میشه و بهتر و عمیقتر یاد میگیرین.
این کتاب چنین نقشی رو براتون بازی میکنه.
اول شروع میکنه پروژه رو نوشتن، بعد مشکل رو عیناً نشونتون میده بعد هم راهحلاش رو با استفاده از الگوهای طراحی یادتون میده.
در کنار این کتاب، کتاب GoF رو هم حتماً مرور کنید.

Le meilleur livre concernant les Design Patterns.

En lieu et place du célèbre catalogue de D.P. du GoF (Gang of Four), ici les concepts et bonnes pratiques de conception sont détaillées.

Les Design Patterns sont illustrés et expliqués pas à pas. On part d'un exemple de base, les auteurs volontairement font des erreurs de conception et expliquent les défauts de telle ou telle conception. Puis à travers l'application des bonnes pratiques, ils expliquent comment on en est arrivé à définir chaque D.P

The patterns themselves are, of course, essential knowledge for any computer programmer. All example code is in Java, but written at such a high level that the basic concepts can be applied to practically any object oriented language.

There is much to learn here, but for each pattern explored, the book beats you over the head with it, telling you the same thing repeatedly, just from slightly different perspectives.

Between the repetition, and the space-filling clip art that is the hallmark of thi

I've seen but not read other books that might've been written by Eric Freeman on Design Patterns, but this one deserves the credit of building a strong foundation on Design Patterns.
One of the many good points about the book is the sequence of Patterns that is follows, building up from Strategic pattern and more importantly building your base with Design Principles which are essential even when you are unable to put any design pattern to implement.
The book highlights the right differences betwee

It is an excellent book. I do not want to be liar, but I knew a little about patterns before. But my knowledge came to a new level thanks to this book. And it is true. Author write about difficult things using simple words. I can say with all responsibility that it is a definite plus. Humor life examples help to better understand material. The book should be a great start guide for programmers who decide to start learning a basic of software architecture.

Head First has always been a series of fun educational books, but I've always been cautious of reading from this series. It might be my serious nature, and my preference for serious books with serious words. It might be the 600 pages (more or less) per book, an amount I am too lazy to read, that I believe is used uneconomically in 1950s inspired pictures.

But this book is amazing addicting.

Every chapter has its own design problem tailored for the design pattern. The writers are Socratic in approa
Jan 31, 2009 Jef rated it did not like it
The book picks a totally artificial application (Simulated Ducks!) and then proceeds to extol the virtues of OO. The important point is glossed over in the first few pages, the majority of the duck application is NOT oop. It's procedural and does not benefit from the OOP patterns. Frankly, I am sick of the promises of OOP. From where I sit in the trenches it has it's place but it doesn't work for everything.

Head First has been my go-to book for any of the technical details I wanted to learn. If Head First published a book for that topic, I will own it and ear mark it with all my extra notes or quotes or whatever. I thoroughly enjoyed all the books I have read by them, but this book did not quite live up to my expectations. Design patterns are slightly dull for an inexperienced programmer. For an experienced programmer, they are just best practices with names coined around them. I am personally some ...more

An amazing display of learning theory in practice. Not only did I learn design patterns from this book (which I tried to do in the past but didn't have the patience for the Gang of Four book), but I learned a lot about teaching and presenting based on the brain-friendly techniques used to keep your attention. This book really is amazing!

At first, I thought this book was cute, an easy read, and simplified a fairly dry topic. By the end, though, I was getting really, really tired of the fluff and repetition, and just wanted it to be over.

While a lot of the visual diagrams were helpful, so much of the book was taken up with silly photos that were fairly irrelevant to the topic. With the exception of a stereotyped asian female, the vast majority of the images seem to be white males working hard on things, and confused females. Cons

Good book. I really enjoyed reading it. I wish I read it years ago when I didn't know most of the patterns, it would have saved me a lot of time. The writer is very knowledgeable and gives pros and cons on using patterns. Also, he explains when it is a bad idea.
Mar 20, 2012 Eduardo rated it it was amazing
Very good book where you can learn - or relearn - the design patterns by the "Gang of Four", such as the abstract factory or singleton patterns with a very entertaining and easy to remember fashion. The best of its kind and a "must have" for any software developer.

My favorite book on application development. App engineers who take their work seriously would do well to familiarize themselves with the design patterns elaborated on here (as well as others -- this book was certainly not comprehensive).

This book serves well as an introduction book to Design Patterns.

As it introduces each pattern with enough background on the problem, the key to understand these patterns is to write your solutions before reading the patterns.
