import java.util.Scanner;

public A(int a,int b){
this.a=a;
this.b=b;
}
public int calculate() {
r = a % b;

}
}

}
}
public class test5 {
public static void main(String[] args){
int a,b;
Scanner sc=new Scanner(System.in);
a=sc.nextInt();
b=sc.nextInt();
A test1=new A(a,b);
B test2=new B(a,b);
System.out.println("最大公约数为"+test1.calculate());
System.out.println("最小公因数为"+test2.calculate2());
}
}
为什么它会报java.lang.ArithmeticException异常？
