Server and Client wont talk to each other

Question

I am trying to make some sort of login system, but the server and client wont talk to each other. I am not quite sure why they wont talk to each other, but any help is appreciated.

P.S The port is correctly set up on my router.

Client

public class Clients implements Runnable
{
String ip = "localhost";
int port = 25565;
Socket client;
static Thread thread;
boolean setup = false;
BufferedReader br;
PrintWriter pw;
public static void main(String[] args)
{
    thread = new Thread(new Clients());
    thread.start();
}
public void run()
{
    while(!setup)
    {
        try {
            client = new Socket(ip,port);
            setup = true;
        } catch (IOException e) {
            setup = false;
        }
    }
    try {
        br = new BufferedReader(new InputStreamReader(client.getInputStream()));
        pw = new PrintWriter(client.getOutputStream(),true);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    pw.flush();
    pw.write("client");
    while(true);
}
}

Server

public class Server implements Runnable
{
int port = 25565;
String input;
ServerSocket server;
Socket clients;
BufferedReader br;
PrintWriter pw;
boolean setup = false;
static Thread thread;
public static void main(String[] args)
{
    thread = new Thread(new Server());
    thread.start();
}
public void run()
{
    try {
        server = new ServerSocket(port);
        clients = server.accept();
        br = new BufferedReader(new InputStreamReader(clients.getInputStream()));
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    try {
        System.out.println("getting input");
        while((input = br.readLine()) != null)
        {
            System.out.println(input);
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
}

You should first do write and then flush

pw.write("client\n");
pw.flush();

Also place \n in the line that you are writing since in the client you are doing br.readline(). So it will wait till a new line is available.
