Java and Recursion.?

Question

ok my program is supposted to return the greatest common divisor of two inputted numbers (i and j), the numbers are already assigned to l(largest) and s (smallest), i need to make a class, so so far i have (for the class) (r = remainder) wehn the remainder is 0, then the smallest should be returned:
public int gcd(int l, int s, int i, int j)
{
int r = l % s;
if (r == 0)
return s;
else
gcd(s,r,i,j);

}

how can you do this without having the error of no return statement ( if the 'if' is not ran) thanks

Thanks so much anal pogrammer
ur the best answer

Answer 1

Change the code to

else
return gcd(s,r,i,j);

That will do it.
