Need help in Override.

I'm in the override section in Java learning (Challenge Task 1 of 2) and cannot proceed to the next question. I've cheched other questions but could not pass this quiz.

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

it says modify the drive method. you don't need to add a field to the class, just a parameter to the method, then add/subtract the parameter value as necessary in the method body. also your -= is backwards.

yep, the first task is to modify the existing method. Also unless you copied incorrectly, you may have misplaced the class's closing } at the end.
