请说出E类中【代码1】和【代码2】的输出结果。interface A(
double f ( double x, double y);
}
class B implements A{
public double f( double x, double y) {
return x*y;
}
int g( int a, int b) (return a+b;
}
}
publie class E(
publie statie void main(string args{ ]) (
System. out.println(a. f(3,5));//【代码1】
System, out.println(b.g(3,5)); //【代码2】 } }
