I can't find what is wrong, it says that I didn't cath the exception
this is my 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"); } kart.drive(2); try { kart.drive(100); System.out.println("This will never happen"); } catch (IllegalArgumentException iae){ System.out.println("Whoa there!"); System.out.printf("The error was: %s\n", iae.getMessage()); } } }
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);
try {
kart.drive(-20);
System.out.println("This will never happen");
} catch (IllegalArgumentException iae){
System.out.println("Whoa there!");
System.out.printf("The error was: %s\n", iae.getMessage());
}
}
}

1,161 PointsYour code is pretty much fine. The only problem is that right above your try/catch block, the drive()-method is called. Since this call is outside of the try, the exception is not caught. Remove it or move it into your try block. The drive(-20) call is not necesarry in the latter case.

4,996 Pointsfirstly there is no need to have two drive methods , drive(2) and drive(-20) Secondly, there is no need to write this statement in try, System.out.println("This will never happen");
you may use the code bellow and give me a shout if it helps
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 iae) {
System.out.println("Alert");
System.out.printf("There was an error: %s\n", iae.getMessage());
}
}
}

12,086 Pointstry {
dispenser.load(400);
} catch (IllegalArgumentException iae) {
System.out.println("Whoa there!");
System.out.printf("The error was: %s%n", iae.getMessage());
}
Above, is the code example to follow. Instead of dispenser.load(400), you are trying kart.drive(2)
