Strategy Pattern

The Strategy Pattern encapsulates interchangeable algorithms behind a common interface and allows the algorithm to be selected independently of the client. It is particularly effective when a method contains a growing if/else or switch statement representing different business rules. Instead of repeatedly modifying the client, I introduce a strategy per behavior and inject or select the required strategy.
