Question

where am l getting it wrong

LandingActivity.java

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class LandingActivity extends AppCompatActivity {

    public Button thrustButton;
    public TextView typeLabel;
    public EditText passengersField;

    public Spaceship spaceship;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_landing);

        thrustButton = (Button)findViewById(R.id.thrustButton);
        typeLabel = (TextView)findViewById(R.id.typeTextView);
        passengersField = (EditText)findViewById(R.id.passengersEditText);

        // Add your code here!
        spaceship = new Spaceship("FIREFLY");
      typeLabel.setText(spaceship.getShipType());

      Int Integer =  spaceship.getNumPassengers().toSring();
      passengersField.setText(Integer.toString(spaceship.getNumpassengers()));



    }
}

Spaceship.java

public class Spaceship {
    private String shipType;
    private int numPassengers = 0;

    public String getShipType() {
      return shipType;
    }

    public void setShipType(String shipType) {
      this.shipType = shipType;
    }

    public int getNumPassengers() {
      return numPassengers;
    }

    public void setNumPassengers(int numPassengers) {
      this.numPassengers = numPassengers;
    }

    public Spaceship() {
      shipType = "SHUTTLE";
    }

    public Spaceship(String shipType) {
      this.shipType = shipType;
    }
}

Hi Glen. Let's have a look at your last 2 lines:

Int Integer =  spaceship.getNumPassengers().toSring();

The primitive type is int (all lowercase), not Int.
Integer is the name of the wrapper class for int in the Android framework, so you cannot name your variable that way. Remember that variable names should start with a lowercase, or the system will read it as a class. You could name it integer (lowercase) but it's best practice to pick descriptive names for your variables. So you could call it numPassengers or numberPassengers for example.
You do not need to call .toString() here as numPassengers (or whatever you decided to call it) is an integer (int), not a string.

passengersField.setText(Integer.toString(spaceship.getNumpassengers()));

You just have a small typo here: it's .getNumPassengers() (capital P).

Hope that helps :)
