Introduction

Working on this project was a valuable learning experience. I deepened my understanding of object-oriented programming, particularly in designing and organizing code using Java. Developing the graphical user interface with Java Swing provided hands-on experience in creating intuitive and responsive user interfaces. Integrating PostgreSQL for database management enhanced my skills in performing CRUD operations and writing efficient SQL queries. Additionally, implementing the MVC pattern and using Maven for build automation and dependency management improved my software architecture and project management abilities. Writing unit tests with JUnit and using Git for version control further reinforced the importance of testing and version management in software development. Overall, this project has significantly enriched my knowledge and skills across various aspects of software development.

Used technologies

• Java: The core programming language for the application.
• Swing: Used for building the graphical user interface.
• Maven: For project management and building.
• JDBC: Java Database Connectivity for interacting with the PostgreSQL database.
• PostgreSQL: Database for storing customer data, product information, and orders.

Dependencies

The project uses several dependencies managed through Maven:

• JDBC Driver: For PostgreSQL connectivity.
• iText: For PDF generation.
• JUnit: For unit testing the application's components.

Description

The system allows customers to view the menu, add products to their orders, apply discounts, manage their accounts, and process orders. The graphical user interface (GUI) is built using Swing, and the application includes features such as customer registration, login, and point management for discounts.
