Question

REPLACE YYY WITH CODE STATEMENTS.....
This is an incomplete version of a client of the question/answer
server qaserver.java.

Complete the program. Comments have been included to
indicate the required tasks. Note that I have used YYY's to
mark places where you must fill in code (not necessarily one
statement).

PROGRAM>

//
// This program asks the user for a question (abbreviated)
// to be asked of the server. It then displays the answer
// sent from the server. Five questions are currently
// supported. "Quit" ends the interaction.
//
// Note that the server is assumed to be running on
// afsconnect1.njit.edu; its port number is given on the
// command-line.
//
// USAGE: java qac <PORT>
//
// where <PORT> is the server's port #.
//

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

public class qac
{
public static final String USAGE = "USAGE: java qac <PORT>";

public static void main(String[] args)
throws java.io.IOException
{

Socket socket;
boolean finished; // controls loop.
String user_question; // question from user.
String answer; // answer obtained from server.
int port; // from command-line.

String hostname = "afsconnect1.njit.edu";

Scanner sc = new Scanner(System.in);

try
{
// use the port indicated on command-line

port = Integer.parseInt(args[0]);

// create a new socket to connect to server, and
// establish write and read capabilities

socket = new Socket(hostname, port);

PrintWriter out = new
PrintWriter(socket.getOutputStream(), true);
Scanner in = new Scanner(new
InputStreamReader(socket.getInputStream()));


// keep getting questions until the user chooses to quit

finished = false;

while (!finished)
{
// get question from the user

YYY

// if input is "Quit", we're finished. Make certain
// to let the server know.
//
// Otherwise, send the question and get a response
if ( YYY )
{
YYY
}
else
{
// send question to server

YYY

// read response and display it

YYY

}
}
out.close();
in.close();
sc.close();
socket.close();

}
catch (IOException e) // socket problems
{
System.out.println(e);
}

catch(NumberFormatException e) // port not a number (int)
{
System.out.println("First argument must be the port number.");
System.out.println(USAGE);
}


catch(ArrayIndexOutOfBoundsException e) // no port # given

} // end main

} // end qac

Explanation / Answer

check this answer i had answered on cramster. I have not tested if this program works. Anyway it should work import java.util.*; import java.net.*; import java.io.*; /** * The Class QAC. */ public class QAC { /** The Constant USAGE. */ public static final String USAGE = "USAGE: java qac "; /** * The main method. * * @param args the arguments * @throws IOException Signals that an I/O exception has occurred. */ public static void main(String[] args) throws java.io.IOException { Socket socket; boolean finished; // controls loop. String user_question; // question from user. String answer; // answer obtained from server. int port; // from command-line.
