Treehouse TeacherThis line seems to be the problem.
GoKart.charge();
Can you try incrementing mBarsCount
in that while loop?

10,365 PointsThanks Craig !
I have done it by my own:
public void charge() { mBarsCount = MAX_ENERGY_BARS;
while (mBarsCount != MAX_ENERGY_BARS) {
mBarsCount++ ;
if ( mBarsCount == MAX_ENERGY_BARS) {
isFullyCharged();
}
}
}
But i dont understand the whole static vs non-static consept ;(
