Java Java Objects Harnessing the Power of Objects Handling Exceptions

Protect the call to kart.drive by handling the IllegalArgumentException that is thrown when not enough battery. HELP!!

i feel i did everthing correctly but still get a syntax error.

Example.java
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);
    } catch(IllegalArgumentException iae) {
      System.out.println(iae);
    }    
  }
GoKart.java
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);
  }

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

}

Here you go, just a few minor changes.

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("Error man, check your laps");
    } catch (IllegalArgumentException iae) {
      System.out.println("Whoa there!");
      System.out.printf("The error was %s",
                        iae.getMessage());
    }
  }

}

This should allow you to complete it.
