public class GoKart {
public static final int MAX_ENERGY_BARS = 8;
private String mColor;
private int mBarsCount;
public GoKart(String color) {
mColor = color;
mBarsCount = 0;
}
public String getColor() {
return mColor;
}
public void charge() {
while(!isFullyCharged()) {
mBarsCount++;
}
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_ENERGY_BARS;
}
}
}
Hope it helps!
Happy coding!

Treehouse TeacherI think there may be a problem in your understanding of the instructions. You're not supposed to change the isFullyCharged method at all. It wants you to modify the charge method to use the value returned by isFullyCharged method.
Ok, the max energy bars are 8. But let's say you're down to 2 and want to recharge it using the charge method. What we want to do is charge until the value returned by isFullyCharged is true. I hope this helps, but if you need further clarification let us know!
