I have been tasked this: The code in Main.java is going to throw an IllegalArgumentException when the drive method is called. Catch it and warn the user.

this is what i added to my code:

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(10);
  } catch (IllegalArgumentException iae) {
    System.out.println("Whoa There!");
    System.out.printf("The error was: %s\n", iae.getMessage());
  }

}

}

But im getting: Bummer! Looks like you didn't catch the exception.

How can i fix this and why does my code not work.

You have to first throw a new IllegalArgumentException("Message"); before you write a try catch statement. Otherwise iae.getMessage() won't work.

Hello Mehrdad,

You have to collapse both kart.drive(2) and kart.drive(10), because the drive() method is the "problematic" method!

Let me know if that worked ? Thanks

what do you mean by collapse? Do you mean to replace them both with kart.drive(12); ?
