The challenge is wanting you to wrap the drive method that is being called in a try/catch block that prints out the error message when they try to drive further than their battery will allow. So what to do: put a try with a curly brace in above the drive method being called and after the method call add another curly brace and then add a catch right after that with IllegalArgumentException iae inside the parenthesis then add another set of curly braces and inside them add a System.out.println message that prints out the error message, like this: System.out.println(iae.getMessage());
