GoKart Laps method-I'm Really Stuck

Hi there,

I'm working on the method signatures challenge, and I'm supposed to make it so that every lap the GoKart takes, it decreasing one of the energy bars. I've tried everything, so anything will help. Here is my code.

GoKart.java 
public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  private int mBarsCount;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }

  public String getColor() {
    return mColor;
  }

  public void drive() {
    drive(MAX_BARS);
    mBarsCount.laps(1);
  }

  public void drive(int laps) {
    // Other driving code omitted for clarity purposes
    mBarsCount -= laps;
  }


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

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

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

}

Add a new method:

public void drive() {
    drive(1);
}
