Whats the default 1 mean?

i am having hard time understanding what the default 1 is for?

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(){

  }

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

}

I think they just mean that if you call the drive method and don't pass in any number of laps, then that method will call the other drive method and pass in a default number of laps of 1.

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

Thanks for your quick reply:)
