4,997 PointsReturning Boolean but not working?
I am returning the boolean result of the mBarsCount == 0 evaluator but the test keeps asking me to return a Boolean...
public class GoKart {
public static final int MAX_BARS = 8;
private String mColor;
private int mBarsCount;
public GoKart(String color) {
mColor = color;
mBarsCount = 0;
}
public String getColor() {
return mColor;
}
public Boolean isBatteryEmpty(){
return mBarsCount == 0;
}
public void charge() {
mBarsCount = MAX_BARS;
}
}

11,616 PointsI think that the problem may be one of case, with Boolean and boolean being different.
Also, sorry about posting this twice. I'm quite new to the forums here, and didn't see the answer section hidden at the bottom of the page.

In Java, Boolean returns true or false, not 0 or 1, which are of type int.

Treehouse TeacherDoh! You're correct. Blurring eyes tonight, sorry.

4,997 PointsYou were right! The uppercase Boolean is valid java but apparently not in the team tree house editor (for at least this challenge). When i lowercased the boolean on the method, it worked perfectly. Thanks!
