Java HTTP Server

A simple, multi-threaded HTTP server implementation in Java that demonstrates basic web server concepts including request handling, routing, and concurrent client connections.

Features

• Multi-threaded: Uses a thread pool with 8 threads to handle concurrent client connections
• Basic Routing: Supports multiple endpoints with different content
• HTTP/1.1 Compatible: Implements basic HTTP protocol standards
• Lightweight: No external dependencies, uses only Java standard library
