Strategy Pattern

Strategy Pattern
The Strategy Pattern defines a family of algorithms, encapsulates each one, and them interchangeable. Strategy lets the algorithm vary independently from clients that use it.

Design Principle

  • Favor composition over inheritance.
  • Program to an interface, not an implementation.
  • Identify the aspects of your application that vary¬† in other words, encapsulate what varies and separate them from what stays the same.
