There were quite a few errors but simply put, a 'try' and 'catch' block work together. You put what you wanna try first and then catch what could happen after.

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.printf("Car cannot drive %s %n", iae.getMessage()); 
    }
  }

}
