The net.sf.json.xml.XMLSerializer class is a utility class for transforming JSON to XML. When transforming JSONObject instance to XML, this class can add hints for converting back to JSON. We can use the write() method of XMLSerializer class to write a JSON value into an XML string with UTF-8 encoding and it can return a string representation of a well-formed XML document.Syntaxpublic String write(JSON json)Exampleimport net.sf.json.JSONObject; import net.sf.json.xml.XMLSerializer; public class ConvertBeanToXMLTest {    public static void main(String[] args) {       Student student = new Student("Sai", "Adithya", 25, "Pune");       JSONObject jsonObj = JSONObject.fromObject(student);       System.out.println(jsonObj.toString(3)); //pretty print JSON ...
