If you would like to use my HW1 as reference this is the code that was used for HW 1:

CLIENT:

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

public class Client {

   public static void main(String argv[])
   {
       try{
           Socket socketClient = new Socket("localhost",5555);
           System.out.println("Client: "+" Connection Established");

           BufferedReader reader =
                   new BufferedReader(new InputStreamReader(socketClient.getInputStream()));

           BufferedWriter writer=
                   new Bufferedwriter(new OutputStreamwriter(socketClient.getOutputStream()));
           String serverMsg;
           writer.write("8 ");
           writer.write("10 ");
           writer.flush();
               while((serverMsg = reader.readLine())!= null) {
                       System.out.println("Client:" + serverMsg);
               }
       }catch(Exception e){e.printStackTrace();}
       }
   }

SERVER:

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

public class Server
{
public static void main(String argv[]) throws Exception
{
System.out.println(" Server is Running") ;
ServerSocket mysocket = new ServerSocket(5555);

while(true)
{
   Socket connectionSocket = mysocket.accept();

   BufferedReader reader =
           new BufferedReader(new InputStreamReader (connectionsocket.getInputStream()));
   BufferedWriter writer =
           new Bufferedwriter(new OutputStreamWriter(connectionSocket.getOutputStream()));
   writer.write("*** Welcome to the calculation Server (Addition Only) *** ");
   writer.write("*** Please type in the first number and press Enter : ");
   writer.flush();
   String data1 = reader.readLine().trim();

   writer.write(*** Please type in the second number and press Enter : ");"
           writer.flush();
   String data2 = reader.readLine().trim();

int num1=Integer.parseInt(data1);
int num2=Integer.parseInt(data2);

int result=num1+num2;
