client number in a java multithread server

I use two classes in my server
private ExecutorService executorService = Executors.newFixedThreadPool(10);        

public static void main(String[] args) throws IOException {
  server = new MyServer();

private void runServer() {        
  int serverPort = 8071;
  try {
    System.out.println("Starting Server");
    serverSocket = new ServerSocket(serverPort); 

    while(true) {
      System.out.println("Waiting for request");
      try {
        Socket s = serverSocket.accept();
        System.out.println("Processing request");
        executorService.submit(new ServiceRequest(s));
      } catch(IOException ioe) {
        System.out.println("Error accepting connection");
  }catch(IOException e) {
    System.out.println("Error starting Server on "+serverPort);

private Socket socket;
BufferedReader input = null;

public ServiceRequest(Socket connection) {
  this.socket = connection;

public void run() {

  try {
    //input = new BufferedReader(new InputStreamReader(socket.getInputStream()));

    DataInputStream din = new DataInputStream(socket.getInputStream());

    System.out.println("Client "+ clientID +"Connected");

I want to get the number of each Client in run() ( I want to get a result in the last line of the code ). How would I do this?


When you create a new service request, you can keep a global counter for IDs... but it's very important to use AtomicLong, not a regular int or long, if you want to keep unique ids.

private static AtomicLong idCounter = new AtomicLong();
private long clientId = idCounter.incrementAndGet();

This is how you can create clientIds in a threadsafe way, as the instance variable clientId will create a new value atomically each time a ServiceRequest is generated.

How to sort an array of UTF-8 strings?

php arrays sorting utf-8

I currentyl have no clue on how to sort an array which contains UTF-8 encoded strings in PHP. The array comes from a LDAP server so sorting via a database (would be no problem) is no solution.
