How to make Java object from XML?

Question

I have a lot of XML files as below. How can I create Java class (Java object) from it automatically? How to update key and value in the String?

`<?xml version="1.0" encoding="utf-8" ?>
   <configuration>
     <appSettings>
       <add key="MODE" value="1"/>   
       <add key="NAME" value="DIRN2"/>
   </appSettings>
</configuration>`

public void createPc("pc.xml"){
      XStream xstream = new XStream();
      Pc newpc = (Pc)xstream.fromXML(pc.xml);

     // updating key and value
       ????????????
 }

Answer 1

Use JaxB. Inorder to create objects, using JaxB, all you need to do is define XSD for your XMLs and generate the classes for your XSD.

Creates automatically the classes you need from the xmls.

You need to marshall and unmarshall it to populate the java objects and update the xml file.
