Java Java Objects Harnessing the Power of Objects Handling Exceptions

Cant find symbol?

` ./Example.java:10: error: cannot find symbol } catch (IllegalArguementException laps) { ^ symbol: class IllegalArguementException location: class Example 1 error ' Its referring to the capital I in the IAE Exception that is the objective of this code. Everything else seems to be in order, I just dont understand why this is not a recognised symbol?

Any thoughts are greatly appreciated.

class Example {

  public static void main(String[] args) {
    GoKart kart = new GoKart("purple");
    if (kart.isBatteryEmpty()) {
      System.out.println("The battery is empty");
    try {
    } catch (IllegalArguementException laps) {
class GoKart {
  public static 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() {
    drive(1); //run one lap

  public void drive(int laps) {
    if (laps > barCount) { //if the number of laps exceed the barCount when it was fully charged
      throw new IllegalArgumentException("Not enough battery remains"); //notify that batteries need charging
    lapsDriven += laps; //increment by one to lapsDriven
    barCount -= laps; //decrement by one to barCount

Within your main method in your Example class, you've misspelled IllegalArgumentException. You added an extra 'e'.

Thank you so much for pointing that out, this has been throwing me for absolutely ages.

It now works like a treat - thank you again for the sharp eye on that spelling!
