Why it is showing 0 in second time?

Question

public class Program
{
public static void main(String[] args) {
int n=94;
int sum=0;
int i=2;
while(n>0)
{
sum+=n%10;
n/=10;
}
System.out.println (sum);
sum=0;
while(n>1)
{
if(n%i==0)
{
sum+=i;

}
else
i++;

}
System.out.println (sum);
}
}

Answer 1

"n" is 0 after the first while loop
