I'm not sure why this is not passing. I meet all of the conditions except #2 and I meet that one I as through an exception if the numbers are not positive after attempting to convert them to positive. Any advice is appreciated.

int b = 0;
try {

b = Integer.parseInt(two);
a = Math.abs(a);
b = Math.abs(b);

throw new Exception("Not a positive number");
}
}
catch (Exception e) {
System.out.println(e);

int gcd = 0;
for (int i = 1; i <= a && i <= b; i++) {
if(a%i==0 && b%i==0) {
gcd = i;

}
System.out.println(gcd);
