Java Java Objects Harnessing the Power of Objects Overload Methods

Methods???

One my public void drive(){ } I dont know why I'm wrong. It says to create a method that has a default of 1

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 morelaps) {
    lapsDriven+=morelaps;
    barCount-=morelaps;
  }

  public void drive(){
    int more = 1;
    lapsDriven+=more;
    barCount-=more;
  }
}

Since you are oveloading drive, I would solve like this:

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

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