Overview
The Strategy pattern allows the algorithm to vary independently from the clients that use it. It is a great alternative to using multiple conditional statements (if/else or switch) to select a behavior.
Key Components
- Context: Maintains a reference to a Strategy object.
- Strategy: Defines an interface common to all supported algorithms.
- Concrete Strategies: Implement the algorithm using the Strategy interface.
Benefits
- Cleanly separates the implementation of an algorithm from the code that uses it.
- Allows switching algorithms at runtime.
