Not sure how to create this new method helper.

The challenge is asking me to create a method helper that only charges this GoKarts battery until it is full. Not sure how to create this method helper?

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;
  }

}

i think it wants you to replace the charge method with:

  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }

Thank you, I actually figured it out right before you answered. I left the mBarsCount = MAX_ENERGY_BARS; pasrt in, added the while loop after that and I passed the challenge. Thank you again!
