A Java-based Customer Ordering System featuring both console and GUI interfaces, demonstrating strong object-oriented programming principles and practical order management functionality.
Overview:
- Designed and implemented the core classes for the system using object-oriented programming (OOP) principles, including encapsulation, inheritance, and polymorphism.
- Developed a UML-modeled class structure for modularity and maintainability.
- Implemented the following classes:
Customer– stores customer details.Product– represents products with attributes like name, ID, and price.Order– manages order details and status.Bank– handles account management, balance updates, and transaction tracking.
Key Features:
- Modular class design for scalable system extension.
- Support for linking orders to customer accounts and bank transactions.
- Ready for integration with console and GUI interfaces.
Overview:
- Developed a menu-driven console application for customer order management.
- Integrated the core classes to allow placing, viewing, and managing orders.
