I have a general question about = programming with=20 recursion in a Java Application. How do I print out the product so far = for a=20 problem that finds the factorial of a number. Example (3! =3D 3x2x1). I = want it to=20 print out the 1, the 2, and the 3; not just the 3. This is the code I = have, but=20 I don't know how to make it show each of the values-it just shows the = final=20 value.

public int findFactorial(int=20 num)
{
   =20 if(num<=3D1)
        return=20 1;
    = else
       =20 return (num*findFactorial(num-1));
}

Thanks. For the = help.
