if(inC.p.x<=outC.p.x+(i-1) && inC.p.x<=outC.p.x-(i-1)) 이부분부터 에러가 나는데

도무지 이유를 모르겠어요



Circle inC=new Circle(1,0,3);에서 인스턴스 p만들어지지 않나요?

그러면 p에 있는  변수 x에 접근할 때 inC.p.x 로 하는게 아닌지 궁금합니다





위에 에러나는부분만 따로 해봤는데

class gib
{
        int x;
        int y;
        gib(int r1, int r2)
        {
                x=r1;
                y=r2;
        }
}

class sib
{

        public sib(int x1, int y1)
        {
                gib p=new gib(x1, y1);
              
        }

}

class some
{
        public static void main(String[] args)
        {
                sib retard=new sib(5, 12);

                System.out.println(retard.p);
        }
}


이것역시 에러에요
