Increment drive challenge

I'm working on the Incrementing Drive challenge. I did the short hand method but it gives me the error " Task one is no longer passing". I'm not sure how this could be. Any help would be appreciated.

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 ++;

Hi Steven

You wrote the increment in the wrong format:

public void drive(){
    lapsDriven ++;//<-- this is should be lapsDriven++ (no space between lapsDriven and ++ increment)

I hope this will help
