Getting Data from Intent Challenge error Part 2 of 2

Here is the code:

import android.os.Bundle;

public class FlightActivity extends Activity {

  public int mFuelLevel = -1;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_flight);

    // Add your code below!
    Intent intent = getIntent();
    String name = intent.getStringExtra("FUEL_LEVEL");
  }
}

Don't know why its not working

The error says:

./FlightActivity.java:14: error: cannot find symbol String name = intent.getStringExtra("FUEL_LEVEL"); ^ symbol: method getStringExtra(String) location: variable intent of type Intent 1 error

Nevermind, I got the answer: I need to change:

    String name = intent.getStringExtra("FUEL_LEVEL");

to 

    Integer name = intent.getIntExtra("FUEL_LEVEL", -1);

Because unlike the example, we are passing in an Int, not a String

Could you please explain why the -1 is needed? I do not remember seeing anything about this during the course. Thanks in advance

If I recall correctly Its because we are also passing in an Int. which in this case is -1. Not just the String: "FUEL_LEVEL"
