Presents a catalog of simple solutions to commonly occurring design problems. These 23 patterns allow designers to create more reusable designs without having to rediscover the design solutions themselves. The authors begin by describing what patterns are, and how they can help you design object-oriented software.

Using the latest research in neurobiology, cognitive science, and learning theory, 'Head First Design Patterns' loads patterns into your brain in a way that sticks. In a way that makes you better at solving software design problems, and better at speaking the language of patterns with others on your team.
