Challenge Task 2 of 2 Help - Method overloading

Hi all,

It's probably really silly what I'm missing here, but I'm uncertain as to how to call in the new drive method AND how to ''pass it a 1 as a default''

Thanks!

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(int laps) {
    lapsDriven += laps;
    lapsDriven -= barCount;
  }

  public void drive() {
    return lapsDriven += 1;
  }
}

It's very simple; you just call the drive() method, passing 1 as its argument.

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