Purpose: Defines a family of algorithms, encapsulates each one, and makes them interchangeable. Strategy allows the algorithm to vary independently from clients that use it.
·
Strategy Pattern, a
useful pattern in changing algorithm implementations at runtime, without causing
tight coupling.
- Use Cases:
- Sorting Algorithms: Different
sorting strategies (e.g., quicksort, mergesort) can be applied to sort
data.
- Payment Methods: In
e-commerce systems, various payment strategies (e.g., credit card,
PayPal) can be selected based on user choice.
