+
+This exercise could benefit from the following rules in the [analyzer]:
+
+- `actionable`: If the solution hardcodes the number of planet classes in `randomPlanetClass`, instruct the student to use `length` method instead.
+- `informative`: If the solution uses Java version >= 17 and [`RandomGenerator.nextDouble(double)`][nextDouble(double)], inform the student that they could use [`RandomGenerator.nextDouble(double, double)`][nextDouble(double, double)] to achieve a clearer solution.
+- `informative`: If the solution uses Java version >= 17 and [`RandomGenerator.nextInt(int)`][nextInt(int)], inform the student that they could use [`RandomGenerator.nextInt(int, int)`][nextInt(int, int)] to achieve a clearer solution.
+- `informative`: If the solution uses `String.format` in the `randomShipRegistryNumber` method, inform the student that this cause a small performance penalty compared to string concatenation.
+
+If the solution does not receive any of the above feedback, it must be exemplar.
+Leave a `celebratory` comment to celebrate the success!
