exercise task 3

Question

hi in task 3 my exercise say: 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!
and my question here which value i convert to string ? please help me i'm stuck here

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!
      mSpaceship = new Spaceship("FIREFLY");
      mTypeLabel.setText( mSpaceship.getType());
      mPassengersField.setText(mSpaceship.getNumPassengers().toString());

    }
}

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;
    }
}

You are attempting to do everything correctly, but using .toString() in this line is not how you convert an int to a string:

mPassengersField.setText(mSpaceship.getNumPassengers().toString());

A quick Google search for "java int to string should show you the correct method to use. Hint: it's a static method on the Integer class

Integer.<insert correct method here>();
