This document discusses how to work with XML files in Java. It provides examples of using JAXB to generate XML files from Java objects and parse XML files into Java objects. Code samples are given to demonstrate how to: 1) Create a Java class to represent an employee object and annotate it for XML conversion 2) Write a program that takes an employee object and generates an XML file 3) Create Java classes to represent objects in an XML file containing a list of horses and their attributes 4) Use JAXB to export a list of horse objects to an XML file and import an XML file back into a list of horse objects.
