What If We Implemented a State Machine to Help the Little Mouse?
summary
A 45-minute session that builds a state machine from scratch in Java to manage a complex workflow. It uses a concrete use case—the “tooth fairy” process involving collection, cavity checks, ordering and receiving parts from the Bank of France, database saves, callbacks and final delivery under a pillow—to show how a state-machine pattern replaces tangled if-else logic and coordinates internal/external service calls.
