davis-ty / client_server

Java client-server app using sockets: Client sends input to server, receives modified responses. Server handles multiple clients concurrently. Demonstrates networking and multithreading in Java.

Client_Server

• This Java program consists of a client-server application using sockets for communication.

Client (client.java):

• The client establishes a connection with the server using the localhost address and port 4999.
• It reads user input from the console and sends it to the server.
• The client continues sending input until the user types "END".
• The client also listens for responses from the server and prints them to the console.

Server (server.java):

• The server listens on port 4999 for incoming client connections.
• Upon accepting a connection, it creates a new thread (MultiClientHandler) to handle client requests concurrently.
• The MultiClientHandler thread receives messages from the client, converts them to uppercase, reverses the words and letters, and sends the modified message back to the client.
• The server continues listening for and processing client requests indefinitely.

MultiClientHandler (MultiClientHandler.java):

• This class represents a thread responsible for handling communication with a single client.
• It receives messages from the client, processes them (converts to uppercase, reverses words and letters), and sends the modified message back to the client.
• Upon receiving the "END" message from the client, it closes the connection and terminates the thread.
• This application demonstrates the use of sockets for establishing communication between a client and server, as well as multithreading to handle multiple client connections simultaneously. It showcases basic networking concepts and concurrent programming techniques in Java.
