Observer and Strategy Patterns
Implement Observer for dependency management and Strategy for interchangeable algorithms.
Behavioral Patterns: Actions & Interactions
Welcome to the world of Behavioral Design Patterns! These patterns focus on how objects interact and communicate, helping distribute responsibilities effectively.
They describe common communication patterns between objects, making your system more flexible and manageable.
Observer Pattern: Notifying Changes
First up is the Observer Pattern. Imagine you subscribe to a newsletter – when a new edition is out, you get notified! This pattern works similarly.
- It defines a one-to-many dependency between objects.
- When one object (the Subject) changes state, all its dependents (Observers) are notified and updated automatically.
It's great for event handling and distributed systems.
