                                                BufferedReader br = new BufferedReader(new InputStreamReader(

                                                                                System.in));

                                                System.out

                                                                                .println("Enter the number of Element for XML files: - \n");

                                                int num = Integer.parseInt(br.readLine());

                                                System.out.println("Enter the root Element: \n");

                                                String rootElement = br.readLine();

                                                Element element = document.createElement(rootElement);

                                                document.appendChild(element);

                                                for (int i = 1; i <= num; i++) {

                                                                System.out.println("Enter the Element:- \n");

                                                                String strElement = br.readLine();

                                                                System.out.println("Enter the Data: - \n");

                                                                String strData = br.readLine();

                                                                Element childElement = document.createElement(strElement);

                                                                childElement.appendChild(document.createTextNode(strData));

                                                                element.appendChild(childElement);

                                                }

                                                TransformerFactory transFactory = TransformerFactory.newInstance();

                                                Transformer transformer = transFactory.newTransformer();

                                                DOMSource domSource = new DOMSource(document);

                                                StreamResult streamResult = new StreamResult(System.out);

                                                transformer.transform(domSource, streamResult);

                                } catch (Exception e) {

                                                System.out.println(e.getMessage());

                                }

                }

}

Result:-

 Note:- After the successful execution of above program, the final xml which we will get is as follows:-
             

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<student>

<studentId>1234</studentId>

<studentName>Arnold</studentName>

<birthDate>1985-11-26</birthDate>
