Java: Observer Pattern
Answer
Observers react to events without being explicitly called.
In the Observer Pattern, observers automatically respond to changes in the subject without direct invocation, allowing workflows to be triggered invisibly. For instance, in an e-commerce checkout, observers like inventory update systems can adjust stock levels without explicit calls in the checkout code.
