    * (<tt>"[]"</tt>).  Adjacent elements are separated by the characters
    * <tt>", "</tt> (comma and space).  Elements are converted to strings as

    * square bracket, and iterates over the collection appending the string
    * representation of each element in turn.  After appending each element
    * except the last, the string <tt>", "</tt> is appended.  Finally a right
    * bracket is appended.  A string is obtained from the string buffer, and
    * returned.
