String.toUpperCase() seems not there on Spark Core. What should I use to convert entire String to upper case or lower case?
Seems like it is: http://docs.spark.io/firmware/#string-class-touppercase
How are you determining that it’s ‘not there’ ?
It is definitely there–it does its work “in place”, that is, it does not return a value:
String myStr = "foo"; myStr.toUpperCase();
Thanks bko, it worked.
