    (1) String is all in uppercase.
    (2) Sting is all in lowercase
    (3) If the string has any numeric values

    Having read copeg suggested lesson on Regular Expressions I am even more confused. The lessons makes little sense to me and seems very complicated. Also having read it I cannot instanly see the solution.

    A simpler way would be to look at the characters one by one using a String class method to get the character. Then use some of the Character class's methods to test the characters.

    Another technique: change the String to all one case and compare it to the original.
    If you don't understand my answer, don't ignore it, ask a question.
