Head First Design Patterns: Building Extensible and Maintainable Object-Oriented Software 2nd Edition 2nd Edition

I didn't expect much, but this covers a lot of great basic design patterns, and its examples are top notch. I could do with a little less of the "fun" cartoon stuff, that's just filler, but if you skip over the filler, the actual information it gives is awesome.It is a little cartoony at times, and it does have a lot of random "fun" things like pictures of people with dialog bubbles saying stuff. I could really do without all that, but the core examples and design patterns are awesome. Personally, I just wish they would cut out like 60% of the random "conversations" and "gurus" and "people" and include 60% more design patterns instead. Still a really solid book though.Examples are in Java and they're great. Very straight forward and easy to follow. You can understand the idea just by glancing at the code. Has a lot of good designs. You're bound to already be familiar with some of the "design patterns", but I find that if even one gives me some new ideas or makes me think about things in a new way, then it was worth the purchase price. I've loved it so far personally.

fantastic book

I've had the book for about a year and wish that I had read it years ago. It's been helpful in expanding software architecture knowledge and applying the information to help others in software development.

So far I'm in to the second chapter. It's a dense topic so be prepared to think but it does make the gof algorithms very approachable. I'm an early to mid stage Dev so I'm trying to brush up for career progression.

Very good introduction to design patterns especially if you have never used them before or are relatively new to some OO principles. The pace is nice and slow at first, but can get tedious after some time with every chapter describing a made up (not real world) scenario and how someone might approach the problem with a simple solution. Then it shows how this simple solution has quite a few drawbacks and introduces that chapter's design pattern. After going through many of these, the 600 pages to read felt quite tedious and I wish that it only did so with about 5 patterns and then did a quick overview of the rest, sort of like how the appendix goes over 9 patterns with 2 pages each, but maybe a little more like 10. That would have made this book a lot more consumable, but I had to force myself to get through the entire thing so I would rate it 4 stars for being excellent but docking that one star because it was too long. Sort of like this review. Haha.

It is like a summertime child book with puzzles. That makes learning funny and effective imo

Great book

What a book completely full of knowledge. A must to read!!
