Get multiple Input/Output Stream from same socket ?

Question

For a better express of my problem i will put my test example
I have those 4 classes
package test;
import...
public class ReaderExecutor extends Thread{
        private InputStream in = null;
        private static int defaultID = 0;
        private int ID = getID();
        public ReaderExecutor(InputStream in){
            this.in = in;
        public void run(){
            try {
                int c ;
                while ((c=in.read())!=-1)
                    System.out.println("ReaderThread " + this.ID + ":" + c);
            catch (IOException e) {
                System.out.println("ReaderThread "+this.ID+" stopped !");
        private static int getID(){
            return defaultID++;
package test;
import...
public class WriterExecuter extends Thread{
    OutputStream out = null;
    private static boolean odd = true;
    private boolean isOdd ;
    public WriterExecuter(OutputStream out) {
        this.out = out;
        isOdd = odd;
        odd = !odd;
    public void run(){
        try{
            for (int i = isOdd?1:2;i<10;i+=2){
                System.err.println(i);
                out.write(i);
        }catch(Exception e){
            System.out.println("WriterThread stopped !");
package test;
import...
public class Main { 
    public Main() {
    public static void main(String[] args) throws Exception {
        try{
            ServerSocket ss = new ServerSocket(9090);
            System.out.println("Ascult ... ");
            Socket client = ss.accept();
            new ReaderExecutor(client.getInputStream()).start();
            //Thread.sleep(2000);
            new ReaderExecutor(client.getInputStream()).start();
        }catch (Exception e){
            e.printStackTrace();
package test;
import...
public class Main1 {
    public Main1() {
    public static void main(String[] args) {
        try{
            Socket s = new Socket("localhost",9090);
            WriterExecuter t= null ;
            t = new WriterExecuter(s.getOutputStream());
            t.start();
            t = new WriterExecuter(s.getOutputStream());
            t.start();
        }catch(Exception e){
            e.printStackTrace();
}Now if i run successive Main , Main1 i get this output
Ascult ...
ReaderThread 0:0
ReaderThread 1:0
ReaderThread 0:0
ReaderThread 1:0
ReaderThread 0:0
ReaderThread 1:0
ReaderThread 0:0
ReaderThread 1:0
ReaderThread 0:0
ReaderThread 0 stopped !
ReaderThread 1 stopped !The question is can i get other Input/Output individual streams with a separate logic functionality from the same socket?
From this example it seems i can't :(
Thx
Alex

Answer 1

For what you are trying to do the simplest solution is to have one socket per "stream" that is the way they are designed to be used.
However, you can multiplex multiple stream over a single socket, but you have do the coding yourself or use a solution which does this for you e.g. JMS. (There is no support at the socket level for this)
