I don't get this challenge. I can't simply figure it out.

Please help me with this challenge..

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);

        // Add your code here!
        Spaceship mSpaceship = new Spaceship();

        public LandingActivity (String FIREFLY)
          {    
          }    
    }  

}
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;
    }
}

Which part are you stuck on? What is the question for that part? Thank!

This is the challenge:

" 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 have tried several options, but nothing works...

It wants you to call the constructor using new.

mSpaceship = new Spaceship("FIREFLY");
