A multi-window Java retail application enhanced for the CI553 module at the University of Brighton in 2021. The original Catshop project was forked and expanded with new functionality such as product quantity merging, GUI improvements, sounds, sorting features, and full JUnit testing.

Catshop is a simulated retail system with multiple interfaces:
- Customer Client
- Cashier Client
- BackDoor Client
- Pick Client
- Display Client
- Collect Client
Customers can:
- Browse items by product ID
- View quantity and price
- Place or remove orders
- Receive unique order numbers
- Collect items when ready
- Eclipse IDE – used after IntelliJ failed to run the provided code
- Git & GitHub – for cloning and version control
- WhiteStar UML – used for modeling Use Case & Sequence Diagrams
- JUnit – for automated unit testing
- JavaDoc – for project documentation
When the same product is added again, the quantity increases rather than creating a duplicate entry in the basket.
Mouse hover effects added using MouseListener and button colors to improve UX.
Custom sound class plays sounds on key interactions using a designated /sound folder.
Improved order display by sorting items by their ID in the BetterBasket class.
Implemented removeItem functionality allowing customers to remove specific items by product ID.
- Implemented JUnit tests for key features.
- Verified GUI behaviors and core logic independently.
- ✅ Use Case Diagram
- ✅ Customer & Cashier Client Sequence Diagrams
Created using WhiteStar UML.
- Generated using JavaDoc plugin in Eclipse for method-level documentation.
