Product Description

The existing books on design patterns take a "catalog" approach, where they show the individual design patterns in isolation. This approach is fundamentally flawed because you can't see how the design patterns actually function in the real world. Most programmers learn by looking at computer programs. Holub on Patterns: Learning Design Patterns by Looking at Code teaches you design patterns in exactly this way: by looking at computer programs and analyzing them in terms of the patterns that they use. Consequently, you learn how the patterns actually occur in the real world and how to apply the patterns to solve real problems. This book also looks at the broader context of object-oriented (OO) design and how patterns solve commonplace OO design problems. It covers many of the principles of OO design--principles not covered by most books on Java--and shows you how to apply these principles to make your code easier to maintain and debug.

4.0 out of 5 stars Refreshingly opinionated, 16 Dec 2005

By	M. W. Walker (Newport, S. Wales) - See all my reviews (REAL NAME)

I enjoyed the original columns on JavaWorld, and this book is more of the same. Holub doesn't spare the punches when referencing so-called O-O frameworks that are riddled with procedural code. Demolishes the "familiarity is correct" thinking that so much software is filled with. Will set right next to Jeff Langr's Essential Java Style on my bookshelf.

4.0 out of 5 stars A good read for the serious programmer, 5 May 2005

By	T. Wiffen - See all my reviews (REAL NAME)

This book is full of excellent ideas to improve the maintainability of you code. The problem is that most software engineers struggle to really think in an object oriented way, instead they write procedural objects. This book helped me think more OO.

Things that I've taken from this book are that getters and setters are evil and a nice improvement to the publish-subscribe pattern.

There is a very large chapter on writing an SQL engine that is a little hard work and there are a number of sloppy errors in the text (e.g. code not exactly matching description) otherwise it's a great read. Good to dip in and out of whilst working on any project.

4.0 out of 5 stars An excellent book for any programmer, 6 April 2009

By	David J. Gardner (London, UK) - See all my reviews (REAL NAME)

I'm actually a PHP programmer but purchased this book after reading Allen's articles on Javaworld. This book is opinionated; and this is no bad thing. It is 100% better than many programming books that concentrate on churning out the popular line of the day. This book actually makes you think.

It can be a bit hard going in places (especially for a PHP developer!), but it is worth it. I often find myself dipping into the design pattern overviews at the end of the book.

Highly recommended. A very interesting discussion of OO, especially, as other reviewers have commented, in a world where most "OO" programmers use OO constructs to create procedural programs.
