Oncreate method- some confusion.

Question

I am a bit confused by this code challenge, I need to have "FIREFLY" as parameter, but if I do how do I implement it? It would be different from the others in On create. At the moment I get this error message.

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);
        mSpaceship( Spaceship, String "FIREFLY");
        // Add your code here!
    }
}

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;
    }
}

Hi Ashley,

In this part of the challenge, you want to put a Spaceship object into the variable that's already declared, called mSpaceship.

For this, we use a constructor for the Spaceship class. It has two; one that defaults the name of the ship to "SHUTTLE" and the second that we can pass a string into. It is that one we want to use.

You've got the right idea in your code; you know you want to create a spaceship and that it needs a string. Let's tidy your code up a little. First, we want to assign an object into the variable, so we'll need an equals sign. We then want to create a new Spaceship called "FIREFLY":

mSpaceship = new Spaceship("FIREFLY");

I hope that helps - let me know how you get on with the rest of the challenge.

Steve.
