Strategy Pattern

Problems we want to solve

1. A set of interchangeable algorithms or objects that can be decided at run-time
2. Extensible set of strategies: Open-Closed Principle

Context refers or uses the Strategy interface for performing the algorithm. A and B classes implement the Strategy interface which gives the concrete algorithms.

Pros

1. Encapsulation
2. Hides implementation
3. Allows behaviour change at runtime

Cons

1. Complexity if overused
