Hi;
working with fractions which i absolutely hate ( ).........uggh but anywhoo. i'm getting a "int can not be derreferenced" error but i don't see why. All i'm doing is comparing to values to see if they are equal. I'm not using a pointer. What can i do to correct this?

here is my code.

You're treating a primitive like an object--why not just say r1 == r2???

True, for reference variables. But are we dealing with reference variables or primitive variables here?

Hi Vee,

Your code convention is wonderful.You wrote the code as a great developer.

Come to the point,
Stein and david are correct.You are treat the primitives as a values and

with out reference of class RationalNumber how can you call the method of the RationalNumber.

so try to access the methods like reciprocal... by using the object of RationalNumber
