ChatBuzz - Online Chat Application

Introduction

ChatBuzz is a simple online chat application developed using Java. It allows multiple users to connect to a central server, send messages, and receive messages from other users. This project assesses skills in socket programming, client-server communication, and user interface design.

Prerequisites

  • Java Development Kit (JDK) installed on your machine.
  • A terminal or command prompt for running the application.

How to Compile and Run

Server

  1. Open a terminal or command prompt.
  2. Navigate to the directory containing the ChatServer.java file.
  3. Compile the server code using the following command: 
    javac server/ChatServer.java
  4. Run the server using the following command: 
    java server.ChatServer

Client

  1. Open a terminal or command prompt.
  2. Navigate to the directory containing the ChatClient.java file.
  3. Compile the client code using the following command: 
    javac client/ChatClient.java
  4. Run the client using the following command: 
    java client.ChatClient
  5. Repeat steps 1-4 in separate terminal or command prompt windows to simulate multiple clients.

Architecture

The application consists of two main components:

  1. Server (ChatServer): Manages connections from multiple clients and broadcasts messages to all connected clients.
  2. Client (ChatClient): Connects to the server, sends messages to the server, and receives messages from other clients.

Assumptions

  • The server runs on 127.0.0.1 and listens on port 12345.
  • The client connects to the server using the same IP and port.

Usage

  • After starting the server, open multiple clients.
  • Type messages in one client and press Enter to send the message.
  • Messages will be broadcasted to all connected clients.
  • Close a client window to simulate client disconnection.
