Sales application
Cheese shop 🧀

Built as part of a SAÉ (Learning and Assessment Situation), this application simulates an online cheese shop. Developed entirely in Java with a Swing graphical interface, it relies on a multi-window architecture using nested JDialogs for each step of the customer journey - browsing the catalog, managing the cart, entering information and editing the invoice.

• Cheese catalog with filters by milk type and format (half / whole)
• Shopping cart respecting stock limits, with edit or clear options
• Customer information form
• Summary invoice generation with print option

• Empty cart: a message is automatically shown if the cart is empty at checkout.
• Three types of cheese available: cow, goat and sheep milk.
• Limited stock: a warning message appears if the requested quantity exceeds stock, and "Out of stock" appears once stock reaches zero.
• Quantity editing in the cart: the matching cheese's stock updates in real time.
• Shipping costs: free for orders over €120, otherwise a fee applies.
• Three carriers available: Chronorelais, Chronofresh and Colissimo.
• Full customer form: name, surname, address, postal code, city, phone, email, payment method and newsletter opt-in.
• Invoice window: full summary with customer details, cart contents, cheese total and shipping cost if the order is under €120.
• Responsive interface: all windows adapt to screen size.
