what is wrong with my code

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 boolean battery ()
  {
   boolean wasBatteryEmpty = false ;
    if (isBatteryEmpty())
    {

      while (!isFullyCharged())
{
    mBarsCount ++ ;
}

    wasBatteryEmpty = true ;
    }
  return wasBatteryEmpty;
  }


  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;
  }

}

Hi Ahmed,

you need a method called "charge" that increments the mBarCount if the battery is not completely charged. But this time the Bars count will not be set to the maximum like the first "charge" method. In will be incremented "step by step". Don´t be surprised by using a second "charge" method :)

public void charge() {
    while (! isFullyCharged()) {
// while the batterx is not fully charged
      mBarsCount++;
// increment the count by one and proof again
    }  
  }

You have the right direction by using the while loop in your code.
