Question: Finally, notice that our Spaceship class has a new field to store the number of passengers in the ship. Use the method to get the number of passengers for mSpaceship, and then set the text for mPassengersField to this value. Note: You will need to convert the int value to a String!
My Code:
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class LandingActivity extends Activity {
public Button mThrustButton;
public TextView mTypeLabel;
public EditText mPassengersField;
public Spaceship mSpaceship;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_landing);
mThrustButton = (Button)findViewById(R.id.thrustButton);
mTypeLabel = (TextView)findViewById(R.id.typeTextView);
mPassengersField = (EditText)findViewById(R.id.passengersEditText);
// Add your code here!
mSpaceship = new Spaceship("FIREFLY");
mTypeLabel.setText(mSpaceship.getType());
mSpaceship.getType();
mSpaceship.getNumPassagers();
mPassengersField.setNumberPassengers(mSpaceship.getNumPassengers());
}
}
public class Spaceship {
private String mType;
private int mNumPassengers = 0;
public String getType() {
return mType;
}
public void setType(String type) {
mType = type;
}
public int getNumPassengers() {
return mNumPassengers;
}
public void setNumPassengers(int numPassengers) {
mNumPassengers = numPassengers;
}
public Spaceship() {
mType = "SHUTTLE";
}
public Spaceship(String type) {
mType = type;
}
}

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()));

String.format("%d", mSpaceship.getNumPassengers());
In case you need to concat another string with the number of passengers, do this:
String anotherString = "My number is";
String.format("%s : %d", anotherString, mSpaceship.getNumPassengers());
Good luck!
