Smellections is the world's smelliest collection classes. It was created by Industrial Logic's Joshua Kerievsky to help people learn about code smells and refactoring. Smellections includes several classes, including a List, Set and Map class:The code (which you can study on the following page) is utterly filled with smells! We call this a Scavenger hunt because you are going to go looking for smells in Smellections.AdviceTo get the most out of this exercise, please take your time! Some folks spend over 30 minutes studying the code before deciding which smells go where.
