Accessing Socket in actionPerformed function

[Realm Head]

I have a Main class that creates the Socket object, and a UserLogin class that has a GUI to get some text as input.
My problem is that I am not able to access the same Socket object within the actionPerformed function of UserLogin.
I mean s.isClosed() returns TRUE within submitActionPerformed(ActionEvent ae)

I tried to solve it by making it final... but didn't work.

/* Code for Main.java  */

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;

public class Main {
    static DataInputStream din;
    static DataOutputStream dout;
    /** Creates a new instance of Main */
    public Main() {
    }

    public static void main(String[] args) {

        boolean listening = true;
        try {
            final Socket s = new Socket("localhost", 112);
            s.setKeepAlive(true);
            new UserLogin(s).setVisible(true);
            
            s.close();
        } catch (UnknownHostException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
    
}

/* Code for UserLogin  */

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.net.Socket;
import java.net.SocketException;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JFrame;
import javax.swing.JTextField;

public class UserLogin extends JFrame {
    static Socket s;
    /** Creates a new instance of UserLogin */
    public UserLogin(Socket sk) {
        s = sk;
        initComponents(s);
    }
    
    public void initComponents(Socket s) {
        final Socket fs = s;
     uname = new JLabel();
     nametf = new JTextField();
     rollno = new JLabel();
     rollnotf = new JTextField();
     uclass = new JLabel();
     classtf = new JTextField();
     submit = new JButton();
        try {
            s.setKeepAlive(true);
        } catch (SocketException ex) {
            ex.printStackTrace();
        }

/*
      ALL THE CODE FOR GUI (irrelevant to the question) IS PLACED HERE   
*/
     
     submit.setText("SUBMIT");
     add(submit);

        System.out.println("inside initComponents: "+s.isClosed());        // This returns FALSE
     submit.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                final Socket s = fs;
                submitActionPerformed(evt, s);
            }
        });
     
    }

    public void submitActionPerformed(ActionEvent ae, Socket s) {
        System.out.println("inside submitActionPerformed: "+s.isClosed());         // This returns TRUE
        new ProcessMessage(s).clientMessage("send any information");
    }
