Thread: JProgressBar not showing

Hello,
I am new to java and I made a app that installs Tic-tac-toe on your computer and when it is supposed to display a progress bar it doesn't.
My code is:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.lang.*;
import java.util.*;
import java.io.*;
import java.util.concurrent.TimeUnit;
 
public class Installer {
 
    JFrame frame = new JFrame("Installer");
    JLabel dir = new JLabel();
    JPanel dirPanel = new JPanel();
    JButton selectButton = new JButton("Browse");
    JButton okButton = new JButton("Confirm");
    JPanel okPanel = new JPanel();
    JFileChooser fc = new JFileChooser(System.getProperty("user.home") + "//Downloads");
    String directoryRaw;
    String directory; 
    JProgressBar loading = new JProgressBar(0, 100);
    JFrame frame2 = new JFrame("Installing...");
 
    public static void main(String[] args) {
        Installer m = new Installer();
        m.frame.setSize(500, 120);
        m.frame.setLocationRelativeTo(null);
        m.frame.setVisible(true);
        m.dir.setText("Select A Directory:       ");
        m.dirPanel.add(m.dir);
        m.dirPanel.add(m.selectButton);
        m.okButton.setEnabled(false);
        m.frame.add(m.dirPanel, BorderLayout.NORTH);
        m.okPanel.add(m.okButton);
        m.frame.add(m.okPanel, BorderLayout.SOUTH);
        m.fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
        m.selectButton.addActionListener(new ActionListener() {
 
            // Override the actionPerformed() method
            public void actionPerformed(ActionEvent e){
                //Handle open button action.
                if (e.getSource() == m.selectButton) {
                    int returnVal = m.fc.showOpenDialog(null);
 
                    if (returnVal == JFileChooser.APPROVE_OPTION) {
                        File file = m.fc.getSelectedFile();
                        //This is where a real application would open the file.
                        m.directoryRaw = file.getAbsolutePath();
                        System.out.println(m.directoryRaw);
                        m.dir.setText(file.getAbsolutePath() + "       ");
                        m.okButton.setEnabled(true);
                    } else {

                    }
               }

Any help is very appreciated.
