Example: the singleton pattern: Programming Foundations: Object-Oriented Design

The Singleton design pattern is a programming approach to the problem of making sure you only ever have one object of a particular class at any time. The approach involves effectively hiding the object so that it appears to not exist until the first time it is called. On the second and subsequent times it's called, the object is returned with no need to create it again. Learn more in this online video "Example: the singleton pattern."
