Help Java Exceptions

Im not sure what I did wrong?

Main.java 
public class Main {
    public static void main(String[] args) {
        GoKart kart = new GoKart("yellow");
        if (kart.isBatteryEmpty()) {
          System.out.println("The battery is empty");
        }
        kart.drive(2);

      try{
      kart.drive(200);
      }
      catch(IllegalArgumentException iad) {
        System.out.printf("Error is %s", iad getMessage());

      }

Where is the exception at? What is the exact error?

Hi Chris,

An error will be thrown when kart.drive(2) is called - we have to catch that error. Also, I noticed that your getMessage() call is not attached to the IllegalArgumentException object. To call a method on an object, use the dot . separator: iae.getMessage().

Edit: changed name of IllegalArgumentException object from iad to iae.

try {
  kart.drive(2);
} catch (IllegalArgumentException iae) {
  System.out.printf("%s", iae.getMessage());
}

Hope this helps,

Cheers
