TCP socket

Hi, I am new to TCP socket. I have a question about socket. I need modify the TCP Client program below, to fetch the webpage at: www.cs.montclair.edu/~wangd/pubs.html. I run the code below, but got an 404 error.

Any inputs are appreciated.

Below is the code.

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

class TCPClient {  
   public static void main(String argv[]) throws Exception
   {    
         String sentence;  
       String modifiedSentence;
     
      BufferedReader inFromUser = new BufferedReader(new InputStreamReader(System.in));  
       
        Socket clientSocket = new Socket("cs.montclair.edu", 80);

      DataOutputStream outToServer = new
DataOutputStream(clientSocket.getOutputStream());  
      BufferedReader inFromServer = new BufferedReader(new
InputStreamReader(clientSocket.getInputStream()));    

     System.out.println("Type in any sentence: ");    
     sentence = inFromUser.readLine();    
    System.out.println(" in sentence: "+sentence);
     outToServer.writeBytes("GET/~wangd/pubs.html" + '\n');  
    outToServer.flush();
    modifiedSentence = inFromServer.readLine();  
    System.out.println("FROM SERVER: " + modifiedSentence);    
    clientSocket.close();    
    }
}
