I've been trying to fix this code for some time now and it still doesn't work. I want to the client to send some text to the server, and for the server to respond with hardcoded text from an array. I can get the server to receive and display text from the client, but not vice versa. My command prompt freezes up as well after you write two lines to the server, which may be because of the text from the array being sent from the server. Sorry if the code is a bit sloppy.

import java.io.*; import java.net.*; import java.util.*; class IT420Client { public static void main (String args[]) throws Exception { String in=null; Scanner scan= new Scanner(System.in); String sentence; //from server Socket clientSocket = new Socket("localhost", 62789); // Create an output stream and connect it to the socket DataOutputStream outToServer = new DataOutputStream (clientSocket.getOutputStream()); // Create an input stream and connect it to the socket BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); System.out.println("write something. to exit loop type \"exit\""); in=scan.nextLine(); outToServer.writeBytes(in+"\n"); while((in.equals("exit")||in.equals("EXIT"))==false){ in=scan.nextLine(); outToServer.writeBytes(in+"\n"); outToServer.flush(); while((sentence=inFromServer.readLine())!=null){ while(true){ sentence=inFromServer.readLine(); System.out.println("from server: "+sentence);} } //}while(in.toUpperCase()!="EXIT"); //Destroy socket outToServer.close(); clientSocket.close(); } }

import java.net.ServerSocket; import java.net.Socket; import java.io.BufferedReader; import java.io.InputStreamReader; import java.io.*; import java.io.IOException; public class server3 { private static int count=0; private static ServerSocket serverSocket; private static Socket clientSocket; private static BufferedReader bufferedReader; private static BufferedWriter bufferedWriter; private static String inputLine; private static String[] bears={"i am a bear", "are your a bear"}; public static void main(String[] args) { // Wait for client to connect on 63400 try { serverSocket = new ServerSocket(62789); clientSocket = serverSocket.accept(); // Create a reader bufferedReader = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); DataOutputStream outToClient = new DataOutputStream (clientSocket.getOutputStream()); // // Get the client message //while((inputLine = bufferedReader.readLine()) != null) System.out.println(inputLine); outToClient.writeBytes(bears[count]); // count++; // } catch(IOException e) { System.out.println(e); } } }
