How to solve Drive and Catch Challenge?

The code in Main.java is going to throw an illegalArgumentException when the drive method is called. Catch it and warn user. Where is my code going 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);
    }
}

Hi Aaron,

I added markdown to help make the code more readable. If you're curious about how to add markdown like this on your own, checkout this thread on posting code to the forum . Also, there is a link at the bottom called Markdown Cheatsheet that gives a brief overview of how to add markdown to your posts.

Cheers!

I copy / pasted your code into the challenge and found that it needed two more closing curly braces at the end. Adding these passed the challenge.

Hope this helps,

Cheers
