The code in Main.java is going to throw an IllegalArgumentException when the drive method is called. Catch it and warn t

I keep getting an error that says the exception wasn'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");
        }
        try {
         kart.drive(2);
        } catch(IllegalArgumentException e) {
          System.out.println("Whoa there!");
          System.out.printf("The error was: %d\n", e.getMessage());
        }
    }
}

Hey there! I can't tell you why it doesn't give you a better error message than the exception not being caught but the error is in your printf call. Using %d is saying that you will be passing in a decimal integer but the call to getMessage() on the exception object returns a String. it should be replaced with 

System.out.printf("The error was: %s%n", e.getMessage());
