题目内容
请写出E类中【代码1】~【代码4】的输出结果。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)); //【代码1】System.out.println(b.g(3)); //【代码2】A a = new B();System.out.println(a.f(10.0,8.0)); //【代码3】System.out.println(a.g(3)); //【代码4】}}
