I got syntax error: Cannot find symbol isFullyCharged after i've put that in while condition, please help!

I've wrote this under the charge method while (!isFullyCharged) { mBarsCount++; }

then there goes the syntax error when i tried to check the work, i'm sure that it isn't a mistype

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

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

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

}

Hi Jordia,

I see an little error:

 public void charge() {
    while (!isFullyCharged()) { // --> () added for method call
      mBarsCount++;
    }
  }
