Courses Plus Student 6,497 PointsI was able to get it to work using this code:
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(100);
} catch (IllegalArgumentException iae) {
System.out.println("Alert");
System.out.printf("There was an error: %s\n", iae.getMessage());
}
}
}

14,002 PointsHi Paul,
First read carefully the question:
The code in Main.java is going to throw an IllegalArgumentException when the drive method is called. Catch it and warn the user.
It tells you you're going to have an exception thrown from that code... it tells you that the problematic method is drive()
.
When they ask you to Catch it..., it means you have to encapsulate the kart.drive(2)
part of code with the try...catch
block and even it shows you which exception type to catch: ...IllegalArgumentException...
Till now you know that you have to encapsulate the kart.drive(2)
code with try...catch
block like this:
try {
kart.drive(2);
} catch (IllegalArgumentException e) {
}
Because they ask you to ...warn the user. then you have to provide a useful message on the body the of catch
block like this:
try {
kart.drive(2);
} catch (IllegalArgumentException e) {
System.out.println("An error has occurred while trying to call drive() method" + e.getMessage());
}
Tried to explain a bit, hope it helps :D
Happy coding!
