No such method exist in standard Java library.

But the String and Character classes has toUpperCase/
toLowerCase/isUpperCase/isLowerCase methods that you
can use to achieve this.

String.toUpperCase
Character.toUpperCase

It seems to be this is exactly where you would expect to find them,
with the names you would expect, a fortunate event in Java. Where did
you expect to find such functions, or did you just assume you would
have to roll your own?

I understood the question as asking if there's a swapCase function
that will change all lower-case letters to upper-case letters and vice-
versa. I don't think such a function exists, but I don't think it
would too hard to write one.
