You're developing a software system where different components need to be notified of changes in a specific object. Which design pattern would you use, and why?
- Adapter
- Factory
- Observer
- Strategy
The Observer design pattern is the most suitable for notifying different components about changes in a specific object. This pattern establishes a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. This ensures loose coupling between the subject (the object being observed) and its observers, promoting flexibility and maintainability in the system.
