    while(!isFullyCharged){
    mBarsCount++;
    wasCharged = true;
    }
    return wasCharged;


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

Hi Benjamin,

Please see the code below:

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;
     // when battery is not fully charged mBarsCount is incremented by one bar
    while (!isFullyCharged()) {
        mBarsCount++;
  }
  }

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

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

  }

}

This should help you get past the compiler error. If you have any other questions -- don't hesitate to ask them.
