The Peer to Peer File Sharing is a Java project that combines Client module and Connection manager, built with Socket API. 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 Connection manager and Socket API, 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 Client module, orchestrated with Socket API and Connection manager. 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.

Modular Java application around Client module and Connection manager
Configurable settings and validation rules
Clear logging, error handling, and reporting
Clean interface for user interaction
Reusable components for related features
Unit testing and maintainable code
The project is layered: the input layer handles user interaction through Client module; the logic layer implements business rules with Socket API and Connection manager; and the output layer presents results via Logging. Shared validation, storage, and logging modules support all layers, keeping the application robust and easy to extend.
