Building a Java Chat Application with Uppercase Conversion

Socket programming allows multiple clients to communicate with a server, making it an ideal solution for creating chat applications. In this post, we will walk through a simple implementation of a chat application in Java that employs threading to handle multiple clients and converts incoming messages to uppercase.

The Problem

The goal is to create a chat application where clients can send messages to a server, and the server will respond by converting those messages to uppercase. Each client is allowed to send at most two messages. The server will be capable of handling up to five clients simultaneously.

Solution Overview

To implement this solution, we will create two primary classes:

Server Class: Manages the connections from clients and handles incoming messages through threading.

Client Class: Connects to the server and sends messages input by the user.

Server Implementation

Let's break down the server code step-by-step:

Key Components of the Server:

Server Socket: Listens for client connections.

Client Handler: Each connected client is assigned a new thread to independently handle interactions without blocking others.

Uppercase Conversion: In the run method, messages are read from the client and printed in uppercase before responding.

Client Implementation

Now, let's look at the client code:

Key Components of the Client:

Socket Connection: Connects to the server’s socket.

Input Handling: Receives prompts from the server to send messages and indicates when to terminate the connection.

Conclusion

In summary, this guide demonstrated how to implement a simple chat application using socket programming and threading in Java. Each client can send messages to the server, and the server processes and returns these messages in uppercase.

This kind of architecture not only simplifies communication between clients and the server but also provides scalability to handle multiple clients effectively.

Feel free to modify and expand this code to build more advanced features into your chat application!
