JAVA CLIENT–SERVER VOTING SYSTEM

Custom multi-threaded client-server voting system in Java supporting TCP communication,
vote management, and request logging.

This project implements a simple voting system as part of a Networks coursework project.
The server maintains voting options and handles multiple client connections concurrently
using a fixed thread pool. Clients can view the current vote counts or cast votes, and all
requests are logged in log.txt. Thread-safe synchronization ensures accurate vote counting
under concurrent access.

FEATURES

• Multi-threaded server with fixed thread pool
• TCP socket-based client-server communication
• Thread-safe vote updates using synchronization
• Logging of all valid client requests (log.txt)
• Client commands: list to view votes, vote <option> to cast a vote

TECHNOLOGIES

• Java
• TCP Sockets
• Multi-threading & Executors

LEARNING OUTCOMES

This project demonstrates practical understanding of:

• Networked client-server architecture
• Multi-threaded programming and thread safety
• TCP socket communication
• Logging and request handling in server applications
