Head First Design Patterns

“I received the book yesterday and started to read it on the way home... and I couldn’t stop. I took it to the gym and I expect people saw me smiling a lot while I was exercising and reading. This is tres ‘cool’. It is fun but they cover a lot of ground and they are right to the point. I’m really impressed.” — Erich Gamma, IBM Distinguished Engineer, and co-author of Design Patterns “‘Head First Design Patterns’ manages to mix fun, belly-laughs, insight, technical depth and great practical advice in one entertaining and thought provoking read. Whether you are new to design patterns, or have been using them for years, you are sure to get something from visiting Objectville.” — Richard Helm, coauthor of “Design Patterns” with rest of the Gang of Four - Erich Gamma, Ralph Johnson and John Vlissides “I feel like a thousand pounds of books have just been lifted off of my head.” — Ward
