java - XML DOM createchild takes Node instread of Element -


I am making XML using the DOM below using online examples, 

  DocumentBuilderFactory docfac = DocumentBuilderFactory.newInstance (); DocumentBuilder docb = docFactory.newDocumentBuilder (); Document doctor = docb.newDocument (); // root element root element = (element) doc.createElement ("test"); Doc.appendChild (rootElement); // Compiler Error ...   
 AppEngine node takes an object, not element object. I was trying to use node, but it seems that there is no way to set up the attribute, so I can not really use nodes.  
 Any help really appreciates it.  
 Thank you.   
 
 
 Please confirm the package you imported:  import org.w3c Dom.Document  and  import org.w3c.dom.Element;  and  docfac.newDocumentBuilder () ;  
 Type is not required to enter  org.w3c.dom.Element  because  doc.createElement ("TEST")    Org.w3c.dom.Element  which is a sub-interface of  org.w3c.dom.Node .  
  org.w3c.dom.Element rootElement = doc.createElement ("TEST"); Doc.appendChild (root element)
