String Constructor challenge

The instructions say: The LandingActivity interacts with the Spaceship model object we created. Start by setting mSpaceship to a new Spaceship object in the onCreate() method. Use the custom constructor that takes a String parameter, and pass in "FIREFLY" as the parameter.

I'm not exactly sure how to do this. Obviously what i tried hasnt been working.

LandingActivity.java
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);


        Spaceship mSpaceship= new Spaceship();



    }
}
Spaceship.java
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;
    }
}

You're 95 percent done, just set the new spaceship you passed into mSpaceship to FIREFLY. It looks like this:

Spaceship mSpaceship = new Spaceship("FIREFLY");

Nicolas the mSpaceship was already declare so the code wil be:

mSpaceship = new Spaceship("FIREFLY");

spaceship = new Spaceship ("FIREFLY"); it worked out for me. this part of the question actually tells you what to do: Start by setting spaceship to a new Spaceship object in the onCreate() method
