        public static int compare​(java.lang.Object a,
                          java.lang.Object b)
                   throws NotComparableException
        compares a and b in the sense of the java.lang.Comparable if possible

        instances of the Number interface are treated specially, in order to allow comparing Numbers of different classes, for example it is allowed to compare a Double with an Integer. if the Numbers have the same class, they are compared normally, otherwise they are first converted to Doubles and then compared

        Parameters:
        a - an object
        b - another object
        Returns:
        the result of a.compareTo(b) if this makes sense
        Throws:
        NotComparableException - if the two objects are not comparable
