Java Web Development Techdegree Graduate 23,933 PointsHey Alex,
The drive method can throw an IlegalArgumentException, so to handle this exception (if it's thrown) you need to wrap the main method's call to kart.drive(42) in a TRY-CATCH block.
Hopefully that points you in the right direction?. Let me know if you have any more questions!

13,520 Pointsyour main method should look like this
class Example {
public static void main(String[] args) {
GoKart kart = new GoKart("purple");
if (kart.isBatteryEmpty()) {
System.out.println("The battery is empty");
}
try{
kart.drive(42);
}catch(IllegalArgumentException iae){
System.out.println(iae.getMessage());
}
}
}
