예:

  record Point(int x, int y) {}

  static void printSum(Object obj) {
    if (obj instanceof Point p) {
      int x = p.x();
      int y = p.y();
      System.out.println(x + y);
    }
  }

빠른 수정 적용 후:

  record Point(int x, int y) {}

  static void printSum(Object obj) {
    if (obj instanceof Point(int x, int y)) {
      System.out.println(x + y);
    }
  }
