Java Java Objects (Retired) Harnessing the Power of Objects Handling Exceptions

Not sure what to do

The exercise is: The code in Main.java is going to throw an IllegalArgumentException when the drive method is called. Catch it and warn the user. I am really having some trouble in this objects course, and I am not quite sure what it is asking for here.

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);
    }
}

Since the drive() method is going to throw an exception you need to put it in a try block, and print a warning to the user in the catch block. It will look something like this:

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("Exception thrown: " + e); 
        }
    }
}
