Java XML and JSON

This book describes the popular XML and JSON data-interchange languages. You’ll explore each language and learn how to parse/create XML-based documents and parse JSON-based documents via various Java APIs. You will also learn how XML and JSON are applied and used in AJAX (and AJAJ), Android, Big Data, and Web Services contexts, all from the Java perspective.

Each chapter ends with select exercises designed to challenge your grasp of the chapter’s content. An appendix provides the answers to these exercises. A second appendix presents a list of developer questions about XML and JSON along with my answers to these questions.
