[jira] Commented: (LANG-471) I would like to add isLowerCase and isUpperCase methods to WordUtils in the commons.lang package

James Carman commented on LANG-471:
-----------------------------------

I don't know if it belongs in WordUtils.  I'd say put it in StringUtils.  You might also want to call them isAllUpperCase() or isAllLowerCase().
