private static Node getEmployee(Document document, String empno, String name, String job, String manager,String date,String salary,String communication) 
{
    Element employee = document.createElement("Employee");
     employee.setAttribute("empno", empno); 
     employee.appendChild(getEmployeeElements(document, employee, "name", name)); 
     employee.appendChild(getEmployeeElements(document, employee, "job", job));
     employee.appendChild(getEmployeeElements(document, employee, "manager", manager));
     employee.appendChild(getEmployeeElements(document, employee, "date", date));
     employee.appendChild(getEmployeeElements(document, employee, "salary", salary));
     employee.appendChild(getEmployeeElements(document, employee, "communication", communication));
     return employee;

}

private static Node getEmployeeElements(Document document, Element element, String name, String value) {       
Element node = document.createElement(name);        
node.appendChild(document.createTextNode(value));        
return node;   
} 
private static Node getEmployeeElements1(Document document, Element element, int name, int value) {       
Element node = document.createElement(name);        
node.appendChild(document.createTextNode(value));        
return node;   

}
}

现在我的问题是第二个函数是getEmployeeElements1，它给出了错误，因为节点只能接受字符串，所以请告诉我创建整数，日期格式，双..等的节点函数的过程。

Answer 1

对于名称：元素是节点，期望作为参数的字符串是标记名称。将标记名称设置为整数没有任何意义。
对于值：DOM表示是最小的并且不处理高级类型，因此您必须处理代码中的整数/日期/双数据检查，并将其作为String存储到DOM文档中。

您可以使用生成代码的框架并为容器提供类型化数据，这样您就可以确保在节点中存储正确的值（例如：JAXB），但是当您使用本机DOM时，您将不得不仅操纵文本数据。

在这里，您只需使用static String Integer.toString(int i)等方法填充DOM对象。
