In challenge 2 task 2 of overloading methods I am not sure what it means "by passing a 1"? any feedback would be awesome

I am just not sure on what to do next

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 void drive() {
    lapsDriven++;
    barCount--;
  }
  public void drive(int lapsAmount){
    lapsDriven+= lapsAmount;
    barCount-= lapsAmount;
  }
  public void drive(int lapsDriven){
    lapsDriven++;
    barCount--;
  }
}

Sorry, here is the question: Create a new method named drive that accepts no arguments. It should call the newer drive method passing in a 1 for the default.

It passes a 1 to the other drive method as a default number. Basically it's just in case the method is called without a parameter being sent to it so it has a default number to use. Hope that helps
