        public static java.lang.String[] split​(java.lang.String str,
                                       char separatorChar)

        Splits the provided text into an array, separator specified. This is an alternative to using StringTokenizer.

        The separator is not included in the returned String array. Adjacent separators are treated as one separator.

        A null input String returns null.

 StringUtils.split("", *)           = []
 StringUtils.split("a.b.c", '.')    = ["a", "b", "c"]
 StringUtils.split("a..b.c", '.')   = ["a", "b", "c"]
 StringUtils.split("a:b:c", '.')    = ["a:b:c"]
 StringUtils.split("a\tb\nc", null) = ["a", "b", "c"]
 StringUtils.split("a b c", ' ')    = ["a", "b", "c"]
        Parameters:
        str - the String to parse, may be null
        separatorChar - the character used as the delimiter, null splits on whitespace
        Returns:
        an array of parsed Strings, null if null String input
