Instant Messaging Application

This project is a socket-based instant messaging application implemented in Java. It includes two main components: a Server and a Client . The server facilitates communication between clients, allowing them to exchange text messages and files directly.

Features

• Client-Server Architecture : All communication between clients is routed through the server.

• Private Messaging : Clients can send messages or files to other connected clients.

• Connected Clients List : Users can list all active clients via the /users command.

• Text Messaging : Clients can send direct messages using the /send message <recipient> <message> command.

• File Transfer : Clients can send files to each other using the /send file <recipient> <file path> command.

• Client Disconnect : Clients can exit the application at any time using the /sair command.

• Server Logging : The server logs all client connections, including their IP address, date, and time of connection.

Prerequisites

• Java 17 or higher must be installed.

• A terminal or command prompt to run the application.

Commands

• /users: Lists all currently connected clients.

• /send message <recipient> <message>: Sends a text message to the specified recipient.

• /send file <recipient> <file path>: Sends a file to the specified recipient.

• /sair: Disconnects the client from the server.

Server Logs

The server automatically records logs for each client connection in a file named server-log.txt. Each log entry contains the following details:

• Client IP address
• Connection date and time
