Re: AP computer science question
Ahh well I tihnk that the second bolded 'multiply' is calling on the first 'multiply' method. But I don't know what the concept is at all. Is it something like a constructo
*edit* OHHH Is it method overloading?!?! (i'm looking around in my AP barrons book... my new best friend)Last edited by svo; 04062012 at 09:16 PM.

Re: AP computer science question
part a) was that if you call the method multiply(8) then what is the output? I put that it was 8 and here is my reasoning:
1a)
You plug in 8 as the ‘int n’
if ‘n’ equals zero, it will return a value of one, however n is not zero it is eight so we move on
now if 8 modulus 2 is equal to one, meaning that ‘n’ is an odd integer, it returns the value of ‘n’ but it is not as 8 is an even number… so…
finally you do 8 * multiply( 82)
 multiply( 82)
(go through the same process for that)
multiply(6) > not equal to zero and is an even number so it will end up like this
 return 8 * multiply(62)
multiply(4) > not zero and is not odd so we can see that this pattern will eventually lead to: return 8 * multiply(o)
multiply(0) returns a value of 1 so 8*1 is 8

Re: AP computer science question
It's not a constructor because constructors don't have a return type and this method has one (int); in the body of the method it calls itself; it is named 'recursion'. Google is your friend here.
