java.util.MissingFormatArgumentException: Format specifier '%s'

at java.lang.String.format(String.java:2928)

Fix: 

   Check number of %s specifiers in the String and make sure all arguments added in String.format() method.

For example:  String output= "<html><title>%s</title><body>%s</body></html>" ;

String.format(output,"programmersstack","Welcome") ;
