Record pattern can be used

Reports patterns that can be replaced with record patterns.

Example:

  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);
    }
  }

After the quick-fix is applied:

  record Point(int x, int y) {}

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