Drive method

I can't seem to figure this step out. Anyone out there able to explain?

GoKart.java 
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;
  private int lapsDriven;

  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }
  public void charge() {
    barCount = MAX_BARS;
  }

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

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

  public int drive() {
    lapsDriven++;
    barCount--;

  }
}

Hi Lauritz,

At step 1 you must modify the existing drive method by defining it to accept a parameter of type int which you must add to lapsDriven and decrease from barCount. At step 2 just overload the drive function by defining a new one which does not accept any parameter and the only thing it is doing is to call the drive method that accepts a parameter with the value 1 as parameter.
