hi, can you help me with the incrementing quiz

i reached a point where it says : "Something fishy is going on, please only refactor the charge method. and i don't understand what does it mean.

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() {
    while(!isFullyCharged()){
      mBarsCount++; 
    }
     return mBarsCount == 0;
  }

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



}

It means that you modified something different from what the challenge asked you to. The challenge is to refactor the drive method, you have changed the code in the isBatteryEmpty method instead. Which is not what the task asked you to do.

The while loop you have written is actually completely right, the only problem is that it is in the wrong method, if you cut your while loop out of the isBatteryEmpty method and paste it into the drive method (replacing the line that is currently there) then your code will pass the challenge.
