Question

怎么获得一个接口类中所有接口的接口名

controller层接口的所有接口名

Answer 1

import java.util.Scanner;
interface interfaceA{
double method(int n);
}
class A implements interfaceA{

public double method(int n) {
double sum = 0;
for(int i = 0; i <= n; i++){
sum +=i;
}
return sum;
}

}
class B implements interfaceA{

public double method(int n) {
double sum = 1;
for(int i = 1; i <= n; i++){
sum = sum * i;
}
return sum;
}

}
public class exp {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("输入N：");
int n = scanner.nextInt();
interfaceA a1 = new A();
interfaceA b1 = new B();
System.out.println("1到" + n + "的和为：" + a1.method(n));
System.out.println("1到" + n + "的积为：" + b1.method(n));
}
}
