use javax.xml.stream.XMLStreamReader

I use stax to parse xml.



public enum XMLInputFactoryBuilder {



    ;



    private static final XMLInputFactory inputFactory = XMLInputFactory.newInstance();



    public static XMLInputFactory build() {



        if (inputFactory == null) {

            return XMLInputFactory.newInstance();

        }

        return inputFactory;

    }

}


XMLInputFactory only instances once.



public class XMLParse {



    private static final XMLInputFactory inputFactory = XMLInputFactoryBuilder.build();



    public static String format(String xml) {

        XMLStreamReader streamReader = inputFactory.createXMLStreamReader(new StringReader(xml));

        while (streamReader.hasNext()) {

        if (streamReader.isStartElement()) {

            switch (streamReader.getLocalName()) {

                case "Encrypt": {

                    return streamReader.getElementText();

                }

                default:

                    break;

            }

        }

        streamReader.next();

    }

    return null;

    }

}


Is the format method thread safe?



Is there a resource leak in the format method?

          Is this a new Fibonacci Identity?

          Image
          6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
