请说出E类中System.out.println的输出结果(答案中不要存在多余的空格）。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 E {public static void main (String args [] ) {B b=new B () ;System.out.println(b.f(10.0,8.0)) ; //输出结果填第一空System.out.println(b.g(3)); //输出结果填第二空}}
