How does the Strategy Pattern compare to other design patterns?

Can you explain how the Strategy Pattern works?

Sure! The Strategy Pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. This allows the algorithm to vary independently from clients that use it.

How does it compare to the Observer Pattern?

The Observer Pattern is about notifying multiple observers about changes in a subject, while the Strategy Pattern focuses on selecting an algorithm at runtime. They serve different purposes in design.

Are there any scenarios where one is preferred over the other?

Yes, if you need to change algorithms dynamically, the Strategy Pattern is ideal. If you need to maintain a list of dependents and notify them of changes, the Observer Pattern is more suitable.

Can you give me an example of each pattern?

Certainly! For the Strategy Pattern, think of a sorting algorithm that can switch between quicksort and mergesort. For the Observer Pattern, consider a news agency that notifies subscribers about new articles.
