1. Create POJO or bind the schema and generate the classes.
2. Create the JAXBContext object.

Java Architecture for XML Binding (JAXB) provides a fast and convenient way to bind XML schemas and Java representations, making it easy for Java developers to incorporate XML data and processing functions in Java applications.

What is marshalling and unmarshalling in JAXB?

JAXB stands for Java Architecture for XML Binding. As part of this process, JAXB provides methods for unmarshalling (reading) XML instance documents into Java content, and then marshalling (writing) Java content back into XML instance documents. JAXB also provides a way to generate XML schemas from Java objects.
