What are some examples of the strategy pattern in programming?

The strategy pattern is a behavioral design pattern that enables selecting an algorithm's behavior at runtime. Examples include sorting algorithms, payment methods in e-commerce, and different compression strategies.

Can you explain how the strategy pattern is implemented in Java?

Sure! In Java, you can define a strategy interface, then create concrete classes that implement this interface. The context class will hold a reference to a strategy object and can switch strategies at runtime.

What are the benefits of using the strategy pattern?

The strategy pattern promotes flexibility and reusability. It allows you to change algorithms without altering the context, making your code easier to maintain.

Are there any drawbacks to using the strategy pattern?

Yes, one drawback is that it can lead to an increase in the number of classes, which may complicate the codebase. Additionally, it requires understanding the pattern well to implement it effectively.
