Head First Design Patterns, 2E: Building Extensible and Maintainable Object-Oriented Software

Stairway to become a good developer by learning from the system design patterns.

One of the best books if you're just getting started with Design patterns, it's not a reference book but will help you understand the patterns and why and when to use them. the code examples is totally in Java, but there are some adaptations of the code to different languages on the Internet

Awesome book. I'd usually forget what I've learnt about design patterns but this book made me remember design patterns for much longer. It is bad DP reference book but it was never intended to be used as reference.

The way the book is written makes it easy for the reader to comprehend the concepts. I believe it's a great resource for software engineers, especially those who are interested in Object Oriented programming. Because the examples and sample code are written in Java, knowledge of Java is required.

If you have bit of experience programming and want to level up your skills by learning how to approach problems using standard design patterns, this is a very well explained intro.

I really liked this book. It made an important, but what could be a boring a topic, into an interesting read.

Good book tells everything about design patterns with good explanation.

Having been a developer for 20 years I thought I might have a refresh, so wanted a great book, but this isn't it, its not what I expected, the content is very spread out and very easily bore the living life from you, the content could be so much more succinct and easily fit into something a quarter of the size. It seems to waffle on, which I found hard to keep reading. I feel examples could be better so in all I'm not impressed. Don't bother getting this, just googleing the patterns and examples would be much better and cheaper. It's not a keeper for me, I will be returning it. I read the pragmatic programmer before, which was so much better.

Me brinda la información que buscaba, el envío fué muy rápido. Estoy muy satisfecho con mi compra.

Gives great insights on the various design patterns that are there to create scalable systems.

Grab this book to learn design patterns in easy and fun way. It has Java code examples and keeps you engage with every example by answering all those question which arises while solving them. Read dumb questions from book to cover the grey areas as well.

Das Buch erklärt die Design Patterns einfach perfekt! Es macht wirklich spaß, das Buch zu lesen, da hier viele Illustrationen und praktische Beispiele verwendet wurden. Es versucht auch nicht der Ersatz für das Buch der GoF zu sein.

Very technical and well written
