JDirChooser provides a tree control to allow a user select a directory.
Examples:

        JDirChooser dirChooser = new JDirChooser();
        int value = dirChooser.showDialog(null);
        if(value == JDirChooser.OK_OPTION) {
            File file = dirChooser.getSelectedFile();
            System.out.println("Selected File: " + file);
        }
