Please help solving the exercise...

Could you please help me, I guess I missed something important, but I dont know the answer... Thanx!

GoKart.java 
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() {
    mBarsCount = MAX_ENERGY_BARS;
  }

  public boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }

  public boolean isFullyCharged() {
    return mBarsCount == MAX_ENERGY_BARS;
  }

  while (!isFullyCharged()) {
    mBarsCount=--;
   }

}

The challenge states "let's use our new isFullyCharged helper method to change our implementation details of the charge method. "

So, you actually want to modify the charge method. Your while loop should be inside the charge method. Also, you want to increment, not decrement mBarsCount
