Design Patterns, Visualized

For advanced developers who already know at least one mainstream language, this course breaks down 33 classic design patterns through hands-on interactive labs: creational, structural, behavioral, and J2EE enterprise patterns. Every pattern starts from a real design pressure: what it solves, when not to use it, and how to express it in code.
