Reviews from Amazon users which were colected at the time this book was published on the website:

⭐Much easier to follow and read than the gof (gang of four)’s book on design patterns.Design patterns have fallen out of style as SE (software engineering) has gone from (strict)waterfall to (freeform)agile; it’s still useful to know and recognize some of the patterns as the modelling of a solution will typically be the same and already completed by some other devs.Borrow, adapt and put into production 🙂

⭐first, if this material is new to you this is a good primer. accessible and clear. but I would recommend this: if after reading this book you are interested in the subject, purchase the ‘gang of four’ book and martin fowler’s book. to find them just search on ‘design patterns’ on amazon

⭐Very nice to read this book, there is no way you could not understand design patterns after reading this book

⭐I quickly found myself disagreeing with how this book explained patterns, and so I tossed out the book rather than risk polluting my knowledge of design patterns.The author sounds like he researched patterns to write the book, but I don’t think he is a design pattern expert.

⭐I bought this book used but it was as good as new. This is a great book about the Gang of Four and details 23 design patterns to help make programming easier.

⭐The original book by the Go4 is a great book, but like one reviewer stated, “requires a bit of sophistication”. And also it was in C++. However, as time rolled on, more pattern books have come out in the more mainstream languages of today to fill the gap.This book uses Java which is an excellent choice because C# programmers and even VB.NET programmers can understand with relative ease the premise of these patterns from Java.This book is very easy to understand and probably should be the starting point for those just learning patterns. (Or “Head First Design Patterns”, which is also excellent and very entertaining). The writing style of the author is very encouraging and I think beginners to patterns will find it a great starting point.You have to start somewhere and this book fills the gap for beginners in learning the terminology, methodology and practical use of patterns.

⭐Like many other programmers, after reading the seminal Design Patterns by the GoF, I was under the charm, while at the same time quite confused by some of the patterns. I had to get an other book to polish the rough edges.I got this book, and quite frankly I only read one chapter, the one about Flyweights. Now if like me you work in the video game industry, you know full well how important Flyweights are in game dev, and one of the patterns you probably know, like me, in depth.I couldn’t believe what I was reading. This chapter is not merely misleading, it is dead wrong. The code example doesn’t show at all what a Flyweight is. Now the damage was done: how can I learn from patterns I have difficulties with, if that one I know full well is so wrong?I returned the book, did some research and got the one from Christopher Lasater instead. If you want to understand the most cryptic parts of the GoF book, avoid that dummy book and go straight to the Lasater one.

⭐This is a terrific book on design patterns. Each pattern is well explained with numerous examples, including examples where the patterns are already implemented in the Java language. The style is easy-going, making each pattern easier to understand and more palatable. The formal design pattern books may give you trouble, but this one won’t–and all the information in the formal books is packed into this one as well.

⭐OK, I am of the opinion that the “For Dummies” books are generally rushed, vague and not very useful. There are almost always better options. This one though, is a great introduction to design patterns and really improved my code design & structure. It’s also just really well written and in parts quite humorous.The other options for Design Pattern books are HeadFirst design patterns, which has good reviews, although I’ve not read it, and the original text on the subject “Design Patterns: Elements of Reusable Object-Oriented Software” which is supposed to be very heavy going and a little out-dated in some areas. It is strongly referenced in this book, which covers all the major patterns covered in that book & is far easier to read!The examples are very simplistic, but show you clearly the essence of how to use each pattern.My only complaint is that very little time is spent on one of the most popular current patterns – MVC. There are however, many, many online tutorials for MVC so it’s not a big problem.If you’re new to programming and want to know how to structure OO code properly to make it expandable and reusable (and not a horrible mess!), and when to use inheritance and when not to, then I would read this book or something similar.

⭐Before reading this book, I’d struggled to understand some of the design patterns, but afterwards I understood all of them. The book does not use UML, and the examples are in Java, but this does not really matter. Most of the examples are simple and distill the essence of what the pattern doing in easy to understand steps. And what is more I read 3/4 of it in one weekend with great ease!

⭐Great little book- good as a refresher. I like the for Dummies series as they dont tend to take themselves to seriously.This is a good quick read- go for it.

⭐Each design pattern is well explained with a nice anecdote, and easy-to-understand diagrams. They are each introduced slowly in a number of stages, from the very basics of each pattern to more advanced uses.The code examples are also simple to understand by those who have a reasonable knowledge of OO programming, and self-documenting, whilst remaining relevant enough to apply to real-life coding scenarios. Finally, the examples are written in java, making the patterns easy to understand and apply, and simple enough to translate to other programming languages.Overall a very good book for those who wish to further basic programming knowledge, be it self-taught or as part of structured learning.

⭐Excellent
