Courses Plus Student 56,696 PointsI have to assume this is the question you are asking about(Task 2 from Using a Model in the Controller).
Now that we have a model object, update the TextView to use the Spaceship's type property. Remember to use the helpful getter method!
You will need to set the text for the TextView mTypeLabel using mSpaceship's getType method provided. Your answer should look like this.
mTypeLabel.setText(mSpaceship.getType());

Jeremy Faith
Courses Plus Student 56,696 Pointsbrandtvavasour, first you will need to call the setText method on mPassengersField.
mPassengersField.setText();
Inside setText, you need to get mSpaceship's number of passengers using constructor getNumPassengers(). Since the return value is an int need to convert to a string for the setText() method.
Integer.toString(mSpaceship.getNumPassengers())
Finally, you code should look like this.
mPassengersField.setText(Integer.toString(mSpaceship.getNumPassengers()));

1,552 PointsJeremy , thanks alot ! I have a follow up question , I cant recall we learned Integer.toString method .
how come : """ mPassengersField.setText(mSpaceship.getNumPassengers().toString()); """ does not work ? Is it wrong ?
Vishnu Ravindran
4,220 PointsThank you very much Jeremy. Well as Ivan has pointed out since we have not learned the Integer.toString method, instead of the code
Integer.toString(mSpaceship.getNumPassengers())
We can use the code below
String.format("%s",mSpaceship.getNumPassengers())
Where ā%sā would be the format specifier for String. Refer the Formatting String Syntax Documentation in the video to read more.
So our final code would be
mPassengersField.setText(String.format("%s",mSpaceship.getNumPassengers()));
Please do correct me if I am wrong. Thanks
