Sending more than one variables from client to server through socket

I recently learned about sockets in Java and sending information back and forth from client to server through sockets. What I want to achieve is sending 'username' and 'password' from client to server and then have these variables checked against the data in a database.

What would the best way be of sending the values of these two separate values to the server so that it can be verified server side?

client side

clientSocket = new Socket("192.168.56.1", 7777);

        in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
        out = new PrintWriter(clientSocket.getOutputStream(), true);


    //starting the thread
    while(runner == null)
    {
        runner = new Thread(this);

        runner.start();
    }
}
public void run()
{
    String userNameAdminLogin;
    String passwordAdminLogin;
    while(runner == Thread.currentThread())
    {
        userNameAdminLogin = txtUserName.getText();
        passwordAdminLogin = txtPassword.getText();

        out.println(userNameAdminLogin);
        out.println(passwordAdminLogin);
    }

sever side

while(listening)
            {
                clientSocket = ServerSoc.accept();


                in = new DataInputStream(clientSocket.getInputStream());

                BufferedReader is = new BufferedReader(new InputStreamReader(in));

                os = new PrintStream(clientSocket.getOutputStream());

                //How can I save the two seperate cases of data in variables on server side?
                System.out.println(is.readLine());

            }

Kind regards

Arian

If you're writing two lines on one side, you should obviously read two lines on the other side:

String name = is.readLine();
String password = is.readLine();

if you use an ObjectOutputStream you can write entire objects.

Those objects have to be serializable

You can have an object which has got username and password as its attributes.

Serialize the object and then send it . 

class User implements Serializable {  
String userName ;
String Password ;
... 
}

Now use ObjectInput/OutputStream to read / write objects
