Java Java Objects Harnessing the Power of Objects Increment and Decrement

Did the Shorthand Increment for the Drive Method... it is not Completing that Part of the Challenge.

I'm on the Incrementing and Decrementing Challenge. I did the Shorthand Increment for the Drive Method. It isn't passing it. It's saying that Task 1 is no longer passing. I followed the instructions in the video. Is there anything I can to do fix this so I can complete this objective in the challenge?
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 += 1;

It doesnt work, because challenge asks you to use INCREMENTING shorthands, wich is "++". The operator you're using is "+=". They do the same thing, but in the video Craig explains that += adds value to the variable, and ++ increments.
