Question

class A{
public int f(int a,int b){
if(a>b){
int temp=a;
a=b;
b=temp;}
if(b%a==0) return a;
else return f(a,b%a);}}
class B extends A{
public int f(int a,int b){
int m;
m=super.f(int a,int b);
return a*b/m;}}
public class MaxandMin{
public static void mian(String args[]){
A a=new A();
B b=new B();
System.out.println("最大公约数为:"+a.f(int a,int b));
System.out.println("最小公倍数为:"+b.f(int a,int b));}}

Answer 1

m=super.f(int a,int b);
->
m=super.f(a,b);
