I admit i am stuck ;-(

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!

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 = new Spaceship("FIREFLY");
      mTypeLabel.setText(mSpaceship.getType());


        // 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,

The quick way of converting an integer to string is by adding an empty string to the number.

// Add your code here!
mSpaceship = new Spaceship("FIREFLY");
mTypeLabel.setText(mSpaceship.getType());
mPassengersField.setText(mSpaceship.getNumPassengers() + "");

I am still finding difficulties please recheck the three codes I have included in my answer and see if they are correct and if they under the right classes. Thank you in advance.

Yes, this code is correct, you need to make sure you don't change anything else, just add these lines and it will pass. It looks like you passed the first two lines previously, so just do the same as you've done before, then add the last line of code.

The code is correct, I have pasted your other two answers in above. If you put all three of these in, it passes the code challenge without any problems.

Finally, thanx Damien!
