Nice step-by-step @kfrajer. However, we can exceptionally have `static` fields inside inner classes as long as they’re `final` & either primitive or String; b/c in this case, they become compile-time constants: 😀

```auto
void setup() {
  final AutoCar car = new AutoCar();
  println("Planet:", car); // Planet: MARS
  exit();
}

class AutoCar {
  static final String PLANET = "MARS"; // Compile-time constant

  @Override String toString() {
    return PLANET;
  }
}

```
