Hi there, there were 2 things that I noticed about the code in the last 2 methods. For this following method you were missing the name of the variable in the parameter section as so:

  public void drive(int numberOfLaps) {//Added "numberOfLaps" after "int"
    lapsDriven += numberOfLaps;
    barCount -= numberOfLaps;
  }

And in the last method, we need to add the "1" into the method call as such:

  public void drive() {
    drive(1);//Passing the number 1 in the overloaded method.
 }

Hope this helps, take care and happy coding !
