how t ocheck if given String is in uppercase or lowercase?

You could compare the result of string.toUpperCase() to the string itself. If it was uppercase already, the 2 strings would be the same. I'll leave it up to you to work out how to check if it's lower case :-)

Or just iterate over the String's chars and ask Character.isUpperCase().

I know that you already have solved the problem, but another option would be to use regexp.

I would have used String.matches(String regex) instead :)
