5.xml中使用的封装的XMLUtil工具类

XMLUtil工具类有两个功能一个是读取文档和写入文档的方法

public class XMLUtil {
  
    //读取文档的方法
    public static Document getDocument(){
        try {
            Document document = new SAXReader().read(new File("/Users/zk/Desktop/Contact.xml"));
            return  document;
        } catch (DocumentException e) {
            e.printStackTrace();
            throw  new RuntimeException();
        }
    }
    //写入文档的方法
    public static  void  XMLWriter(Document document){
        try {
            OutputStream outputStream = new FileOutputStream("/Users/zk/Desktop/Contact.xml");
            OutputFormat outputFormat = OutputFormat.createPrettyPrint();
            XMLWriter xmlWriter = new XMLWriter(outputStream,outputFormat);
            xmlWriter.write(document);
            xmlWriter.close();

        }catch (Exception e){

            e.printStackTrace();
        }
    }
}
