        public final int compare​(byte[] bytes1,
                                 byte[] bytes2)
        Perform lexicographical comparison of two byte arrays, regarding each byte as unsigned. That is, compare array entries in order until they differ--the array with the smaller entry is "smaller". If array entries are equal till one array ends, then the longer array is "bigger".
        Specified by:
        compare in interface java.util.Comparator<byte[]>
        Parameters:
        bytes1 - first byte array to compare.
        bytes2 - second byte array to compare.
        Returns:
        negative number if bytes1 < bytes2, 0 if bytes1 == bytes2, positive number if bytes1 > bytes2.
