What you’ll find in Head First Design Patterns, 2014:
The core design principles and design patterns—everything you need to take your programming skills to the next level.
The same great visual explanations and brain-friendly learning style you’re used to from Head First, with exercises and challenges so the design patterns really sink in.
Updated code! The code for all the examples and exercises now compiles and runs with Java 8.
This is a gimmicky book that actually works for once. It is an intelligent and well thought-out discussion of Java design patterns, and if you dont know what a design pattern is then this is an excellent way to find out. It is also an interested discussion of object-oriented design. I found that the authors often anticipated my reaction to their initial explanations and asked the questions that I would have asked had it been a lecture. - Mike James, VSJ, April 2005

In any event, one area where I knew I was lacking was a formal understanding of design patterns. I was in the middle of a fairly large enterprise application, and while I was fully versed in Object Oriented Programming (and had even taught it in the past), I realized that everyone we were hiring out of college "spoke" a different language than I did, talking about singletons, factories, MVC, etc.
This book covers those and many, many more, in a completely involving and revolutionary way. It's basically designed with the Java language in mind, but I'm a .Net developer, never having learned Java. However, the book is so thorough and intuitive, that I decided to do all of the examples in C# (close enough to Java that in many cases, there's almost a 1-to-1 relationship between my home-grown example and the one in the book.
So for me, the book's benefit was two-fold: exposure to both design patterns and the Java language. In many cases, I was able to ".Net-ify" the examples to take advantage of specific features of .Net. A good example was in the Observer pattern where you have an object that changes over time, and other objects ("observers") need to be aware of this change. The book presents a language-agnostic approach, where the observable object registers all of its observers, and cycles through them notifying each one that it has changed. With .Net, it's much easier (and more appropriate) to implement this using events, where the observable object doesn't care who's watching, it just announces "I've changed!" and each observer can then decide how to handle that event.
But I digress... ultimately, I just threw myself into this book, doing every example as written, and then modifying those examples to function with the .Net mentality. I even did all the pencil exercises, puzzles, etc. It's all part of the learning process, right?
So, in a nutshell, if you need to learn design patterns, get this book. It's a lot of fun, and chock full of great information and examples that you'll be able to apply to your own projects right away.
"Head First Design Patterns" book goes deeply and thoroughly into the motivation of each design pattern so it's more easy to understand all of their aspects and the drawbacks of other alternatives.
The thorough explanations makes it more easy to remember and understand the patterns.
The book is friendly to read and I definitly recommend it to anyone who wishes to understand design patterns.
