Task 3 -- get the passenger number and set to a string

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.

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());
    mPassengersField.setText(passengersEditText.valueOf.get());

    }
}
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 Andreas, you do it pretty much like the line above but add a blank string to the number which converts to a string.

mPassengersField.setText(mSpaceship.getNumPassengers() + "");

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