Number of rows in cursor

Question

I believe this might have been asked multilpe times, but I could not find anything.
Is there any way to get the number of rows in a cursor, when I open the cursor. In my case, I have to do the processing in 3 different ways depending on whether the cursor has A)no rows, B) One row, c) more than one row. I know I can get the number of rows by fetching all the rows and then getting the %rowcount.
I wanted to know whether its possible before fetching any row. The ways I am currently doing it is as follows
blah blah blah is
Cursor cur = <my cursor query>;
cont number;
BEGIN
select count(*) into cont from <things exactly same as my cursor query>
if (cont = 0) THEN
<Processing A>
ELSIF (cont = 1) THEN
<Processing B>
ELSE
<Processing C>
END IF;
END
Is this method better than getting the the cursor, fetching at least 2 rows, if the rowcount is more than one, close the cursor and do the processing based on the rowcount i've got.
TIA
