hey, please help in challenge "handling exceptions"

I have following error - Bummer: Make sure you print out the error message to the console using the exception's getMessage method. but in preview everything seems right, what am I doing wrong?

class Example {

  public static void main(String[] args) {
    GoKart kart = new GoKart("purple");
    if (kart.isBatteryEmpty()) {
      System.out.println("The battery is empty");

  try { kart.drive(42); 
       System.out.println("it will never happen");
    } catch (IllegalArgumentException iae) 

       System.out.printf( "the error was %s" ,
class GoKart {
  public  final int MAX_BARS = 8;
  private int barCount;
  private String color;
  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() {

  public void drive(int laps) {
    int newLapsDriven=lapsDriven+laps;
    int newBarCount=barCount-laps;
    if (newLapsDriven>MAX_BARS||newBarCount>MAX_BARS) {
      throw new IllegalArgumentException( "not enough Battery");
