        public static int compare​(byte[] first,
                          byte[] second)
        Compare the arguments. Shorter arrays are always considered smaller than longer arrays. For arrays of equal lengths, the elements are compared one-by-one. Whenever two corresponding elements in the two arrays are non-equal, the method returns. If all elements at corresponding positions in the two arrays are equal, the arrays are considered equal.
        Parameters:
        first - a byte array to be compared
        second - a byte array to be compared
        Returns:
        0 if the arguments are equal, -1 if the first argument is smaller, 1 if the second argument is smaller
        Throws:
        java.lang.NullPointerException - if any of the arguments are null
