Hello, I am working on a program and trying to add a GUI to it. I want the user to chose a directory for files to be run into the program. I am using a separate class for the GUI and I cant seem to pass the anything from ActionEvent to my main. Is this possible? My code is below. Any help or advice at all would be greatly appreciated.

Code:
public class GUIOptions extends JPanel
implements ActionListener {
	static private final String newline = "\n";
	JButton openButton;
	JTextArea log;
	JFileChooser fc;

	public GUIOptions() {		
		
			super(new BorderLayout());

			log = new JTextArea(25,50);
			log.setMargin(new Insets(5,5,5,5));
			log.setEditable(false);
			JScrollPane logScrollPane = new JScrollPane(log);
			fc = new JFileChooser();
			//fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
			fc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
			openButton = new JButton("Chose a directory");
			openButton.addActionListener(this);
			JPanel buttonPanel = new JPanel(); 
			buttonPanel.add(openButton);
			add(buttonPanel, BorderLayout.PAGE_START);
			add(logScrollPane, BorderLayout.CENTER);
		}



public void actionPerformed(ActionEvent e) {

//Handle open button action.
if (e.getSource() == openButton) {
	int returnVal = fc.showOpenDialog(GUIOptions.this);

	if (returnVal == JFileChooser.APPROVE_OPTION) {
		File file = fc.getSelectedFile();
		log.append("Opening: " + file.getName() + "." + newline);
	//	File[] testFiles = fc.getSelectedFiles();
		//return testFiles;
	} else {
		log.append("Open command cancelled by user." + newline);
	}
	log.setCaretPosition(log.getDocument().getLength());
}
	 
} 

public static void createAndShowGUI() {
    JFrame frame = new JFrame("TestMiningGui");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    frame.add(new GUIOptions());
    frame.pack();
    frame.setVisible(true);
}

public static void main(String[] args) {
	 createAndShowGUI();
            
	File[] testFiles = getFileListFromDirectory(This is where I cant get it to call the user specified directory);
