Method Overloading

Can someone tell me what is wrong with my code?

GoKart.java 
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;
  private int lapsDriven;
  private int laps;

  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 laps) {
  lapsDriven+= laps; barcount-= laps
  }  
  }
}

Sure, happy to help. I see three issues:

  • the instructions for task 1 say to modify the existing method instead of adding another one
  • the new one is currently inside the original one because of brace placement
  • instead of "barcount", it needs to be barCount (with a capital "C")
