    We can also use TextArea to get paths of any file example here for Image File and the name of object TextArea is txtPath, and we make ActionPerformed to JButton named bChoose with the folowing method.

    JFileChooser fc = new JFileChooser();
    FileNameExtensionFilter filter = new FileNameExtensionFilter("Image Files", "jpg", "png", "gif");
    fc.setFileFilter(filter);
    fc.showDialog(bChoose, "Choose File");
    String strPath = txtPath.getText() + "\n" + fc.getSelectedFile().toString();
    txtPath.setText(strPath);

    chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    
    // You can use 
    // chooser.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);  too
    
    File file = chooser.getSelectedFile();
    String fullPath = file.getAbsolutePath();
    

    Then Pass the String to the other method.

    The example in the javadoc show show to do this:

    JFileChooser chooser = new JFileChooser();
    FileNameExtensionFilter filter = new FileNameExtensionFilter(
        "JPG & GIF Images", "jpg", "gif");
    chooser.setFileFilter(filter);
    int returnVal = chooser.showOpenDialog(parent);
    if(returnVal == JFileChooser.APPROVE_OPTION) {
       System.out.println("You chose to open this file: " +
            chooser.getSelectedFile().getName());
    }
    

    That's what chooser.getSelectedFile() is doing. Take the result of that and pass it to another method.
