I can't enter String as a parameter without getting an error message. I'm doing something wrong and can't figure out what.
The error hint at this point says Make sure you set the 'type' for mSpaceship as specified in the instructions. One small problem - I don't see where that is in the instructions. Obviously it's not explicit but I had no clue that's what I was supposed to be doing so apparently I'm totally lost.
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(){
};
}
}
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 need to pass in "FIREFLY" as the parameter
for the constructor and then the challenge will pass.
I do agree that this error message could confuse users though so, I'm going to tag Ben Jakuben here to take this as feedback.
Some students may not look in the Spaceship class to see that it takes in a String which is referred to as the type
in the constructor so, perhaps the error message should say something like
"Make sure you set the parameter for the Spaceship constructor as specified in the instructions."
as otherwise, some students may not know what is meant by the type
.
