The Toll Booth Console System is a Java project that combines Unit tests and Data storage, built with JUnit. The project follows a clean, modular architecture where input handling, business logic, and presentation stay separated, making it easy to test, extend, and present. It showcases practical Java techniques while producing a working, demo-ready application.
Manual and paper based methods for this task are slow, error-prone, and hard to manage. Without a Java application built on Data storage and JUnit, users cannot process, store, and manage data efficiently, and there is no reliable, reusable way to run the workflow.
This project applies Java techniques through Unit tests, orchestrated with JUnit and Data storage. The application is designed for correctness and usability, with clean data flow, validation, and error handling. It produces consistent, reusable results and can be adapted to related tasks with minimal changes.

Unit testing and maintainable code
The project is layered: the input layer handles user interaction through Unit tests; the logic layer implements business rules with JUnit and Data storage; and the output layer presents results via Error handling. Shared validation, storage, and logging modules support all layers, keeping the application robust and easy to extend.
