Question

I’ve got codes of a server and clients written on Java. But the question is how to run multiple clients on DIFFERENT console-windows with Eclipse when server is running? Thx for helping!
(solved!!)

UPDATE**
Another question: I’ll create a new question

Server:

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

public class ATMServer {

    private static int connectionPort = 8989;
    public static void main(String[] args) throws IOException {
    ServerSocket serverSocket = null;
    boolean listening = true; 
    try {
        serverSocket = new ServerSocket(connectionPort); 
    } catch (IOException e) {
        System.err.println("Could not listen on port: " + connectionPort);
        System.exit(1);
    }

    System.out.println("Bank started listening on port: " + connectionPort);
    while (listening)
        new ATMServerThread(serverSocket.accept()).start();
    serverSocket.close();
}

}

ServerThread:

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

public class ATMServerThread extends Thread {
private Socket socket = null;
private BufferedReader in;
PrintWriter out;
public ATMServerThread(Socket socket) {
    super("ATMServerThread");
    this.socket = socket;
}

public void run(){

}
}
}

Client: (**UPDATE)

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

public class ATMClient {
private static int connectionPort = 8989;

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

    Socket ATMSocket = null;
    PrintWriter out = null;
    BufferedReader in = null;
    String adress = "";

    try {
        adress = "127.0.0.1";
    } catch (ArrayIndexOutOfBoundsException e) {
        System.err.println("Missing argument ip-adress");
        System.exit(1);
    }
    try {
        ATMSocket = new Socket(adress, connectionPort); 
        out = new PrintWriter(ATMSocket.getOutputStream(), true);
        in = new BufferedReader(new InputStreamReader
                                (ATMSocket.getInputStream()));
    } catch (UnknownHostException e) {
        System.err.println("Unknown host: " +adress);
        System.exit(1);
    } catch (IOException e) {
        System.err.println("Couldn't open connection to " + adress);
        System.exit(1);
    }




    out.close();
    in.close();
    ATMSocket.close();
}

You can run as many socket clients from Eclipse provided that you pass user-defined ip/port info as command arguments from main() under Program Arguments tab in Run Configuration dialog for that program inside Eclipse rather than using some hardwired values for ip/port.

To create multiple console views (via separate Console View tabs rather than clicking on each instance), you need to create a new console view for each target instance in Eclipse Debug View mode; to achieve this, you need to select “New Console View” (from the icon button with the plus symbol to the far right of the Console View) and assign which program instance to view from each new console.

Another question: if I have to change something on ServerThread, for example, add a title, is that possible to execute that without restart the server?

Which title? I don’t see any GUI code for the ServerThread code snippet. Do you mean the title name of the Console view tab?
