This Java console application simulates a parcel logistics management system.
It allows managing customers, parcels, shipments, hubs, scan events, and delivery attempts, ensuring full traceability from dispatch to delivery or return.
- Create and manage:
- Customers (Sender & Receiver)
- Parcels
- Shipments
- Hubs
- Record real-time:
- Scan events (parcel movement between hubs)
- Delivery attempts and proof of delivery
- Status tracking per parcel with complete timeline
- Shipment summaries showing if all parcels are delivered or returned
- Simple menu-driven console interface
- Every ScanEvent updates a parcel’s status and location.
- DeliveryAttempt records successful or failed attempts.
- A successful delivery requires a ProofOfDelivery (receiver name & code).
- A Shipment cannot be closed until all parcels are either Delivered or Returned.
- Returned parcels are logged with reason and final hub “Returned to Sender”.
