What is exactly the problem here?

Hi Hester,

The Challenge next asks for you to use the Spaceship's method of getType(), and set the text of mTypeLabel using that.

Lastly, the Challenge is asking for you to getNumPassengers from the Spaceship, and convert that number to a string to set it as the text for mPassengersField. The easiest way to do that is to smush the int with an empty String, as below.

      mSpaceship = new Spaceship("FIREFLY");

Please let me know if you have any questions about what's going on there!
