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() {
mBarsCount = MAX_ENERGY_BARS;
}

I think the question mentions using a while loop in the (existing) charge method and the isFullyCharged helper method too. Don't create a new method but rewrite the current charge method.
Currently, charge just sets mBarsCount to MAX_ENERGY_BARS in one go. The aim of this is to increment the charge to add one bar at a time. isFullyCharged can let you know when you have reached the full state, so you need to keep adding until that method ells you to stop.
So, you want to loop through and increment mBarsCount while the isFullyCharged method returns false, i.e. isn't full.
Something like:
while(!isFullyCharged()){
mBarsCount++;
}
I hope that help.
Steve.
