What are the best practices for implementing the Strategy Pattern?

What are the best practices for implementing the Strategy Pattern?

The Strategy Pattern is a behavioral design pattern that enables selecting an algorithm's behavior at runtime. Best practices include defining a family of algorithms, encapsulating each one, and making them interchangeable.

Can you give me an example of how to implement it?

Sure! For instance, if you have different sorting algorithms, you can create a SortStrategy interface with a method sort(). Then, implement classes like BubbleSort and QuickSort that implement this interface.

What are the advantages of using the Strategy Pattern?

The main advantages include promoting code reusability, making it easier to add new strategies without modifying existing code, and adhering to the Open/Closed Principle.

Are there any common pitfalls to avoid?

Yes, common pitfalls include overusing the pattern for simple cases, leading to unnecessary complexity, and not properly managing the lifecycle of strategy objects.
