6,198 PointsI don't understand why this challenge compiler won't accept my code to covert an int to a String.
I need to convert an int to a string and set it to an EditText in this challenge for building an Interactive Story.
I am stuck. I researched info on StackOverFlow, and Oracle, but I just can't seem to understand what it is I am missing. I understand that this challenge compiler is looking for something specific, but I just don't know what specifically it's looking for.
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());
String intAsString = String.valueOf(0);
mPassengersField.setText(mSpaceship.getNumPassengers(intAsString));
}
}
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;
}
}

mPassengersField.setText(String.valueOf(mSpaceship.getNumPassengers()));

mPassengersField.setText(mSpaceship.getNumPassengers() + "");
//You were trying to parse a string into the function that doesn't accept any arguments.
//Simply doing + "" will convert it to string.

6,198 PointsThank you I greatly appreciate the explanation.

6,198 PointsWow, thank you both. I am assuming they both will work just fine, because i did research on String.valueOf() and wasn't aware to think to put the mSpaceship object into the parameters of String.valueOf.
Thank you!
