Эй, я пытаюсь запустить этот программный код сокета.
Это код на стороне сервера -
package sockettest;
import java.net.*;
import java.io.*;
public class Server {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = null;
try
{
serverSocket = new ServerSocket(139);
}
catch (IOException e)
{
System.err.println("not able to listen on port");
System.exit(1);
}
Socket clientSocket = null;
try
{
clientSocket = serverSocket.accept();
}
catch (IOException e)
{
System.err.println("Accept failed.");
System.exit(1);
}
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true); // Out is Outputstream is used to write to the Client .
BufferedReader in = new BufferedReader( new InputStreamReader(clientSocket.getInputStream())); // in is used to read the Client's input.
String inputLine, outputLine;
out.println("Hey! . Who are you?"); // Writes to client as "Hey! . Who are you?"
while ((inputLine = in.readLine()) != null)
{
// Reads the input from the Client. if it is "bye" the program ends.
if (inputLine.equalsIgnoreCase("Bye"))
{
out.println("Bye");
break;
}
else
{
out.println("Hello Mr. " + inputLine);
}
}
out.close();
in.close();
clientSocket.close();
serverSocket.close();
}
}
Этот код выполняется на стороне клиента -
import java.io.*;
import java.net.*;
public class Client
{
public static void main(String[] args) throws IOException {
Socket kkSocket = null;
PrintWriter out = null;
BufferedReader in = null;
try
{
kkSocket = new Socket("192.168.2.3", 139);
out = new PrintWriter(kkSocket.getOutputStream(), true); // Out may be used to write to server from the client
in = new BufferedReader(new InputStreamReader(kkSocket.getInputStream())); // in will be used to read the lines sent by the Server.
}
catch (UnknownHostException e)
{
System.err.println("Unidentified host.");
System.exit(1);
}
catch (IOException e)
{
System.err.println("Couldn't get I/O for the connection to.");
System.exit(1);
}
BufferedReader stdIn = new BufferedReader(new InputStreamReader(System.in));
String fromServer;
String fromClient;
while ((fromServer = in.readLine()) != null) {
System.out.println("Server: " + fromServer);
if (fromServer.equals("Bye"))
break;
fromClient = stdIn.readLine();
if (fromClient != null) {
System.out.println("Client: " + fromClient);
out.println(fromClient);
}
}
out.close();
in.close();
stdIn.close();
kkSocket.close();
}
}
Я запускаю коды на Eclipse как на стороне клиента, так и на стороне сервера.Используя команду netstat -an в командной строке cmd, я вижу, что между клиентом и сервером установлено соединение, но я не могу связаться, и затмение тоже не показывает никакого вывода.Что, кажется, не так ??
