Using the StringTokenizer But Have a Delimiter of "char" type

Question

I am using the java.util.StringTokenizer to break a String into tokens.
The delimiter is common (i.e. ',') and I declare it as a char.
I have a compilation error becasue the StringTokenizer requires the delimiter of the String type. How do I handle the problem?
                        char delimiter =  ',';
                        int longest = 0;
                              StringTokenizer t = new StringTokenizer( letters, delimiter );
                              while ( t.hasMoreTokens() )
                                   String token = t.nextToken();
                                   int length = token.length();
                                   if ( length > longest )
                                        longest = length;
                              }

How do I convert a char to a String?Familiarize yourself with the API for Character and String, I can see about 4 different ways of doing this.
Or do it the shortcut way ;-)char c = 'c';
String s = "" + c;db
edit Now why wasn't #3 on the page before I posted? Forum lagging again?
@OP: The other ways are
-- put the char in a one-element array and use the appropriate String constructor, or static method copyValueOf
-- static method String#valueOf(...)
