If you can drill down into the StringTokenizer class,
look at the scanToken() method.  You'll notice that it
decomposes the "str" one character at a time from a
starting position.  It then asks, "is this character in
the "delimiters" by checking for an indexOf() >= 0.  
So, the approach taken by StringTokenizer to get tokens
is just about backwards from the way you (and many others)
think it should be working (i.e., looking for the string
you give as the delimiters as a substring of the source
string).

If you use the "!" as a delimiter, you can look for "Category"
token in a loop.  When you find it, grab the next token and 
then break out of the loop.
