How do different behavioral design patterns compare?

Behavioral design patterns focus on communication between objects. Some common ones include Observer, Strategy, and Command. Would you like a brief overview of each?

Yes, please provide an overview of the Observer and Strategy patterns.

The Observer pattern allows an object to notify other objects about changes in its state, promoting a publish-subscribe model. The Strategy pattern enables selecting an algorithm's behavior at runtime, encapsulating algorithms within a class.

What are the main use cases for these patterns?

The Observer pattern is great for event handling systems, while the Strategy pattern is useful in scenarios where multiple algorithms can be applied, like sorting or routing.
