java.io.FileNotFoundException /employee.xml: open failed ENOENT (Нет такого файла или каталога) в файле read

Question

При попытке чтения из файла XML я получаю java.io.FileNotFoundException /employee.xml: open failed ENOENT (No such file or directory).

Class, чтобы создать свой файл XML:

public class Filesauv { 
public static void lance() { 

    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); 
    DocumentBuilder dBuilder; 
    try { 
     dBuilder = dbFactory.newDocumentBuilder(); 
     Document doc = dBuilder.newDocument(); 
     //add elements to Document 
     Element rootElement = 
      doc.createElementNS("http://www.journaldev.com/application", "Applications"); 
     //append root element to document 
     doc.appendChild(rootElement); 


     //for output to file, console 
     TransformerFactory transformerFactory = TransformerFactory.newInstance(); 
     Transformer transformer = transformerFactory.newTransformer(); 
     //for pretty print 
     transformer.setOutputProperty(OutputKeys.INDENT, "yes"); 
     DOMSource source = new DOMSource(doc); 

     //write to console or file 
     StreamResult console = new StreamResult(System.out); 
     StreamResult file = new StreamResult(new File("employee.xml")); 

     //write data 
     transformer.transform(source, console); 
     transformer.transform(source, file); 
     System.out.println("DONE"); 

    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    } 
} 

Класс для чтения из моего файла XML и добавить в него:

public class ModifyXMLDOM extends MainActivity { 
    public static void lance(){ 

     String filePath = "employee.xml"; 
     File xmlFile = new File(filePath); 
     DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); 
     DocumentBuilder dBuilder; 
     try { 
      dBuilder = dbFactory.newDocumentBuilder(); 
      Document doc = dBuilder.parse(xmlFile); 
      doc.getDocumentElement().normalize(); 


      //add new element 
      addElement(doc); 

      //write the updated document to file or console 
      doc.getDocumentElement().normalize(); 
      TransformerFactory transformerFactory = TransformerFactory.newInstance(); 
      Transformer transformer = transformerFactory.newTransformer(); 
      DOMSource source = new DOMSource(doc); 
      StreamResult result = new StreamResult(new File("employee.xml")); 
      transformer.setOutputProperty(OutputKeys.INDENT, "yes"); 
      transformer.transform(source, result); 
      System.out.println("XML file updated successfully"); 

     } catch (SAXException | ParserConfigurationException | IOException | TransformerException e1) { 
      e1.printStackTrace(); 
     } 

} 

private static void addElement(Document doc) { 
    NodeList employees = doc.getElementsByTagName("Applications"); 
    Element emp = null; 

    //loop for each employee 

     emp = (Element) employees.item(0); 
     Element appliElement = doc.createElement("application"); 
     Element serviceElement1 = doc.createElement("messagerie"); 
     Element serviceElement2 = doc.createElement("repertoire"); 
     Element serviceElement3 = doc.createElement("calculatrice"); 
     Element serviceElement4 = doc.createElement("calendrier"); 

     serviceElement1.appendChild(doc.createTextNode(m)); 
     serviceElement2.appendChild(doc.createTextNode(re)); 
     serviceElement3.appendChild(doc.createTextNode(ca)); 
     serviceElement4.appendChild(doc.createTextNode(cale)); 

     appliElement.appendChild(serviceElement1); 
     appliElement.appendChild(serviceElement2); 
     appliElement.appendChild(serviceElement3); 
     appliElement.appendChild(serviceElement4); 

     emp.appendChild(appliElement); 
    } 
}

предаю вас на попытку английского языка. Mais, je parle le Francais aussi.

Vous devez utiliser

File f = new File("employee.xml"); 
f.createNewFile(); 

авангард уоиз utilisez Вос программа. Vous n'avez pas un fichier pour ecriver. Донк, vous devez le creer.
