Strategy Pattern

At the end of the lectures on strategy patterns, I was able to understand that a strategy pattern provides a way to configure a class with one of many behaviours. Strategy pattern provides an easier way to extend a model to incorporate new behaviours without recoding the application. This pattern may be applied in a situation wherein you need different variants of an algorithm. GOF defined strategy pattern as “Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.” [GoF]
