请说出A类中System.out.println的输出结果。
class B{
int n;
static int sum=0;
void setN(int n){
this.n=n;
}
int getSum(){
for(int i=1;i<=n;i++){
sum=sum+i;
return sum;
}
}
public class A{
public static void main(String args[ ]){
B b1=new B(),b2=new B();
b1.setN(3);
b2.setN(5);
int s1=b1.getSum();
int s2=b2.getSum();
System.out.println(s1+s2);
}
}
