body: <p>I am trying to read a string which is send from client using Socket program, The code as follows:</p>
  
  <pre><code>import java.io.IOException;
  import java.io.ObjectInputStream;
  import java.io.ObjectOutputStream;
  import java.lang.ClassNotFoundException;
  import java.net.ServerSocket;
  import java.net.Socket;
  
  public class SocketServerExample {
  
      //static ServerSocket variable
      private static ServerSocket server;
      //socket server port on which it will listen
      private static int port = 5000;
  
      public static void main(String args[]) throws IOException, ClassNotFoundException{
          //create the socket server object
          server = new ServerSocket(port);
          //keep listens indefinitely until receives 'exit' call or program terminates
          while(true){
              System.out.println("Waiting for client request");
              //creating socket and waiting for client connection
              Socket socket = server.accept();
              //read from socket to ObjectInputStream object
              ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
              //convert ObjectInputStream object to String
              String message = (String) ois.readObject();
              System.out.println("Message Received: " + message);
              //create ObjectOutputStream object
              ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
              //write object to Socket
              oos.writeObject("Hi Client "+message);
              //close resources
              ois.close();
              oos.close();
              socket.close();
              //terminate the server if client sends exit request
              if(message.equalsIgnoreCase("exit")) break;
          }
          System.out.println("Shutting down Socket server!!");
          //close the ServerSocket object
          server.close();
      }
  
  }
