At any given moment, someone struggles with the same software design problems you have. And, chances are, someone else has already solved your problem. This edition of Head First Design Patterns—now updated for Java 8—shows you the tried-and-true, road-tested patterns used by developers to create functional, elegant, reusable, and flexible software. We think your time is too valuable to spend struggling with new concepts. Using the latest research in cognitive science and learning theory to craft a multi-sensory learning experience, Head First Design Patterns uses a visually rich format designed for the way your brain works, not a text-heavy approach that puts you to sleep. Stay ahead with the world's most comprehensive technology and business learning platform. With Safari, you learn the way you learn best.
When your system has become complex and the flexibility you planned for isn't needed. In other words, when a simpler solution without the pattern would be better.
Design patterns are powerful, and it's easy to see all kinds of ways they can be used in your current designs. Developers naturally love to create beautiful architectures that are ready to take on change from all directions.
Resist the temptation. If you have a practical need to support change in a design today, go ahead and employ a pattern to handle that change.
However, if the reason is only hypothetical, don't add the pattern. It's only going to add complexity to your system, and you might never need it. Filling pages with rah-rah pattern talk, and then tacking this critical guidance on at the end of the book is downright irresponsible.
This advice should be in 72 point blinking Comic Sans on the very first page. Beginning developers never met a pattern or an object they didn't like. Encouraging them to experiment with patterns is like throwing gasoline on a fire. Page outlines how therapeutic it is for beginners to abuse patterns: The beginner uses patterns everywhere.
This is good.
The beginner gets lots of experience with and practice using patterns. The beginner also thinks, "The more patterns I use, the better the design.
Complexity and patterns should only be used where they are needed for practical extensibility. Do you really want a junior developer using patterns everywhere? It's about as safe as encouraging them to "experiment" with a gas-powered chainsaw.
The best way to learn to write simple code is to write simple code! Patterns, like all forms of compexity, should be avoided until they are absolutely necessary.
That's the first thing beginners need to learn. Not the last thing. The book isn't the only thing that's backwards: did you know the Head First girl pictured on the front of the book leads a shocking double life?
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 You're not alone.
With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on Something more challenging.
Something more complex. Something more fun. You want to learn about the patterns that matter--why to use them, when to use them, how to use them and when NOT to use them.
