        try {

            // create a output and input as a xml file
            FileOutputStream fos = new FileOutputStream("properties.xml");
            FileInputStream fis = new FileInputStream("properties.xml");

            // store the properties in the specific xml and a different encoding
            prop.storeToXML(fos, "Properties Example","utf-8");

            // print the xml.
            while (fis.available() > 0) {
                System.out.print("" + (char) fis.read());
            }
