    Socket programming in Java enables communication between programs over a network. Below is a simple implementation of a Client-Server model using Java sockets.

    Server Implementation

    The server listens for client connections on a specific port and processes incoming messages.

    import java.io.*;
    import java.net.*;

    public class Server {
    public static void main(String[] args) {
    try (ServerSocket serverSocket = new ServerSocket(5000)) {
    System.out.println("Server started. Waiting for a client...");

    // Accept client connection
    Socket socket = serverSocket.accept();
    System.out.println("Client connected.");

    // Input and output streams for communication
    DataInputStream input = new DataInputStream(socket.getInputStream());
    DataOutputStream output = new DataOutputStream(socket.getOutputStream());

    String message;
    while (!(message = input.readUTF()).equalsIgnoreCase("exit")) {
    System.out.println("Client: " + message);
    output.writeUTF("Server received: " + message);
    }

    System.out.println("Closing connection...");
    socket.close();
    } catch (IOException e) {
    e.printStackTrace();
    }
    }
    }

    How to use server socket in Java?
    Create the Java class named Server in that class write the main method. Create the instance of the ServerSocket and assign the port as 9090. Accept the client connections using accept () method of the ServerSocket to the wait for incoming client connections.
