Format XMLGregorianCalendar to ‘MM/dd/yyyy hh:mm a z’ Date Pattern

In this example, we will learn to format XMLGregorianCalendar class to string in multiple patterns e.g. ‘MM/dd/yyyy hh:mm a z’.

XMLGregorianCalendar to String in Date/TimeStamp Pattern

In below code sample, I am creating instance of XMLGregorianCalendar with current Date object. Then I am formatting it to String format in given pattern.

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.Locale;
import java.util.TimeZone;

import javax.xml.datatype.DatatypeConfigurationException;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;

public class Main 
{
	private final static String TIMESTAMP_PATTERN = "MM/dd/yyyy hh:mm a z";
	private final static DateFormat TIMESTAMP_FORMATTER = new SimpleDateFormat(TIMESTAMP_PATTERN);
	private final static TimeZone IST_TIMEZONE = TimeZone.getTimeZone("IST");
	
	public static String formatTimeStamp(XMLGregorianCalendar cal)
   {
      if (cal == null)
         return "";
      else
      {
         return TIMESTAMP_FORMATTER.format(cal.toGregorianCalendar(IST_TIMEZONE, Locale.US, null).getTime());
      }
   }

	public static void main(String[] args) throws DatatypeConfigurationException 
	{
		GregorianCalendar cal = new GregorianCalendar();
		cal.setTime(new Date());
		
		XMLGregorianCalendar calendar = DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);
		
		String formmatedDateTimestamp = formatTimeStamp(calendar);
		
		System.out.println(formmatedDateTimestamp);
	}
}

Output:

01/27/2017 01:32 PM IST

You can use above code to parse XMLGregorianCalendar instance in any date pattern of your choice.

Happy Learning!!
