mPassengersField.setText(mSpaceship.getNumPassengers()+"");

3,747 PointsWell here is the explanation than.
mPassengersField is an EditText on your layout.
Challenge is about setting text in that EditText. You are asked to put the number of passengers in your spaceship.
To get number of passengers, you need to use method getNumPassengers(), but since by using this method you will get an Integer you need to add "" so that android thinks its a string.
Now to set text of any EditText or TextView or Button, you need to use method setText.
So all together you have mPassengersField.setText (mSpaceship.getNumPassengers() + "");
Does it make more sense now? :)
