🌐 TCP Multithreaded Server and Client

Welcome to the TCP Multithreaded Server and Client application 🚀 — a Java-based implementation of a TCP client-server model using multithreading. The server can handle multiple clients concurrently, and the client can send messages to the server for an echo-like response. 🖥️

📝 Features

• 🖥️ Multithreaded TCP Server: The server can accept multiple client connections and process them simultaneously using threads.
• 💬 Echo Functionality: The server echoes the received messages back to the client, enclosed in <strong> tags.
• 🚀 Client Communication: The client sends messages to the server and displays the server’s response.
• 🔄 Concurrency: Each client connection is handled in a separate thread, allowing multiple clients to interact with the server simultaneously.

🚀 Getting Started

1️⃣ Prerequisites

Ensure you have the following installed:

• ☕ Java JDK (Java Development Kit) — Version 8 or above.

2️⃣ Installation

Clone the repository and navigate to the folder:

git clone https://github.com/sean-njela/tcp_multithreading.git
cd tcp_multithreading

3️⃣ Usage

Start the TCP Server

To start the server, simply run the following command:

java TCPMultithreading

Start the TCP Client

After starting the server, run the client by executing:

java TCPClient

📂 How It Works

1. TCP Server (TCPMultithreading):

   • The server listens on port 7777 for incoming connections.
   • When a client connects, it spawns a new thread (ServerThread) to handle the communication with that client.
   • Each thread listens for client messages and sends the received message back, wrapped in <strong> tags.
   • This process is repeated for each new client that connects.

2. TCP Client (TCPClient):

   • The client connects to the server running on localhost at port 7777.
   • It sends messages to the server and receives the server's response.
   • Communication continues until the user types "END".

Example Output

Server:

$ java TCPMultithreading
The server is up!
New client connected 192.168.1.100
The Server Thread No. 12 for the client 5001 has started!

Client:

$ java TCPClient
Client with the socket 5001 has started!
Hello Server
Produced content: <strong>Hello Server</strong>
How are you?
Produced content: <strong>How are you?</strong>
END

⚠️ Error Handling

• 🛑 IOExceptions: Any issues during socket communication will result in an exception being printed in the logs.
• ⚠️ Thread Interruption: If the thread is interrupted (for example, if the client disconnects abruptly), an error will be logged.
