I simply want to ask why toUpperCase() and toLowerCase() got deprecated in 1.5 uppercase() and lowercase() seems to have exactly same code, so why rename such a common method name after such stability of the language?

seems to have exactly same code

no, toUpperCase uses Locale.getDefault while uppercase uses Locale.ROOT
