How can Observer Pattern decouple event producers from consumers in Java?
Track: Java
Topic: Software Architecture
Focus: Observer Pattern
Java: Observer Pattern
Answer
By using interfaces for observer communication.
The Observer Pattern uses interfaces to define the contract for communication, allowing the producer to notify consumers without knowing their specifics. This is useful in a system like an e-commerce platform, where a checkout service might inform various modules like shipping and notifications through a common interface, promoting flexibility and maintainability.
