kart.drive(2) has to be only inside the try clause, not repeated above it.

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.printf("IllegalArgumentException: %s", iae);
        }
    }
}

i was talking about the negative one in try

Yes, the parameter for drive() must be positive. But your code had two other problems: (1) you put the try...catch outside the main() method, and (2) you called drive(2) outside a try...catch
