I need help on this 3rd task in this challenge. I am supposed to use the method to get the passenger number and then convert it to a string to display in the textView.
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);
mSpaceship = new Spaceship("FIREFLY");
mTypeLabel.setText(mSpaceship.getType());
mPassengersField.setText(passengersEditText.valueOf.get());
}
}
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(mSpaceship.getNumPassengers() + "");

2,426 Pointsoh okay thank you very much!!! so by adding that blank string it knows to convert it??

27,419 PointsYeh, I think he calls it 'mushing it together', adding an empty string concatenates the number and the string, making a string.
