        static Collector<CharSequence,​StringJoiner,​String> joining​(CharSequence delimiter,
                                                                               CharSequence prefix,

        Returns a Collector similar to the standard JDK joining collector, except that this collector returns an empty string if there are no elements to collect.
        Parameters:
        delimiter - the delimiter to be used between each element
        prefix - the sequence of characters to be used at the beginning of the joined result
        suffix - the sequence of characters to be used at the end of the joined result
        Returns:
        A Collector which concatenates CharSequence elements, separated by the specified delimiter, in encounter order
