Didn't catch the exception!! - IllegalArgumentException

I'm getting an error that the exception isn't caught.

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(3000);

      }catch(IllegalArgumentException iop){
        System.out.printf("The error was %s",iop.getMessage());
      }
    }
}

Hi there,

The drive method is what can throw the exception. There's no try|catch block around the existing method call, kart.drive(2); which is what the compiler is complaining about.

There's no need to call the method again, just build the exception handling around the code that exists:

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

I hope that helps.

Steve.

DRY!!! I had completed this lesson, but in reviewing it I completely forgot about that to the point that I had to look here for the answer. Don't I feel like a dweeb. :D
