Java Java Objects Harnessing the Power of Objects Handling Exceptions

my code is not compiling correctly

i am doing exactly the same but still its not compiling
class Example {

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


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() {

  public void drive(int laps) {
    if (laps > barCount) {
      throw new IllegalArgumentException("Not enough battery remains");

You are not printing the message that displays if not enough battery power remains.

In the try-catch block, print iae.getMessage() as you are doing when you check if the battery is empty.

Thanks Scott, now i understand when you say "print" I need to wrap it in the System.out method
