When should I use the Strategy design pattern in Java?

When should I use the Strategy design pattern in Java?

The Strategy design pattern is useful when you want to define a family of algorithms, encapsulate each one, and make them interchangeable. It allows the algorithm to vary independently from clients that use it.

Can you give me an example of where this pattern might be applied?

Sure! A common example is in sorting algorithms. You can have different sorting strategies like QuickSort, MergeSort, etc., and choose which one to use at runtime based on the context.

What are the benefits of using the Strategy pattern?

The benefits include increased flexibility, easier maintenance, and the ability to add new strategies without modifying existing code.

Are there any drawbacks to using this pattern?

Yes, it can lead to an increase in the number of classes, which might complicate the system. Additionally, it requires clients to be aware of the different strategies.
