Additional Notes
How would you explain a design consequence of the Observer Pattern in an interview?
Track: Java
Topic: Software Architecture
Focus: Observer Pattern
Java: Observer Pattern
Answer
Increased modularity at the cost of potential over-notification.
The Observer Pattern enhances modularity by separating concerns, allowing components to evolve independently. However, it can lead to over-notification if not carefully controlled, where observers receive too many updates, potentially affecting performance. For example, in an e-commerce app, care must be taken to avoid redundant notifications for minor status changes.
