Question

(14 points) write a TCP JAVA socket code to finish the following protocol: Cl) the client type in annual income and send it to server; 2) the server receives client type in income and then require the client to enter hisher dependent number, the his/her dependent number and send it to server; server will compute the client's according tax annual income 20%-number-dependents 1000. total tax in to: Assuming that the I address of server is: 198.98.98.98; the communication port is: 2700 First, draw the infrastructure diagram and flow-chart of client/server (5 points): Second, finish the codes as follows (9 points)

Explanation / Answer

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

public final class MyClient {
   public static void main(String args[]) throws IOException{
       BufferedReader inFromUser = new BufferedReader(new InputStreamReader(System.in));
      
       Socket clientSocket = new Socket("127.0.0.1", 2700);
      
       DataOutputStream outToServer = new DataOutputStream(clientSocket.getOutputStream());
      
       BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
       outToServer.write(8000);
       outToServer.flush();
      
       System.out.println("Srever Asked: "+inFromServer.readLine());
       outToServer.write(2);
       outToServer.flush();
      
       System.out.println("Total Tax :"+inFromServer.readLine());
      
      
   }
}

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

public class MyServer {

   public static void main(String[] args) throws IOException{
      
       ServerSocket welcomeSocket = new ServerSocket(2700);
      
       Socket connectionSocket = welcomeSocket.accept();

       BufferedReader inFromClient = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream()));
      
       DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream());
      
       int income = Integer.parseInt(inFromClient.readLine());
      
       outToClient.writeUTF("Enter Dependent Number: ");
       outToClient.flush();
      
       int dependent = Integer.parseInt(inFromClient.readLine());
      
       int tax = income*(income/100*20)-dependent*1000;
       outToClient.writeUTF(""+tax);
       outToClient.flush();
      
   }
