using XStream to convert between Java objects and XMLXStream is a good thing, easy to convert between Java objects and XML, efficiency and readability are very high, the following is a test example I wrote, let's take a look. The required jar packages are as follows: Xpp3_min-1.1.4c.jar
Xstream-1.3.jar Goal: Convert the persons object to XML, and then convert the XML into a persons object. implementation Source list: Package Com.lavasoft.demo3;

Import java.util.List;
Import java.util.ArrayList;
Import Java.util.Iterator;
