How to Pass it a 1, since that's the default?

Default = 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() {
    lapsDriven (MAX_BARS);
   }
  public void drive(int lapsDriven){
  barCount += lapsDriven;
  }
  public void drive(int lapsDriven){
  barCount -= lapasDriven;
  }

}

Hey rosa! Your a little off here. In the first challenge, you should modify the already existing drive method to take an integer as a parameter, you should add this integer to lapsDriven, and subtract the integer from barCount. After that, in task 2, make another method named drive that takes no parameters, this method should call the drive method that takes an integer, and pass in 1.

Your issue is that you have made two seperate drive functions, one that subtracts from barCount, and one that adds to lapsDriven. Just do this in the same method.

Hope this helps!
