阅读以下程序并写出运行结果：1
class A {
double f(double x, double y) {
return x + y;
}
static int g(int n) {
return n * n;
}
}
class B extends A {
double f(double x, double y) {
double m = super.f(x, y);
return m + x * y;
}
static int g(int n) {
int m = A.g(n);
return m + n;
}
}
public class PrintMethod {
public static void main(String[] args) {
A a = new B( );
System.out.println(a.f(10.0, 8.0));
System.out.println(a.g(3));
}
}
