Cant solve the challange :(

public class Main { public static void main(String[] args) { GoKart kart = new GoKart("yellow"); if (kart.isBatteryEmpty()) { System.out.println("The battery is empty"); }

  if (kart.drive()){
  throw new IllegalArgumentException("The Karts battery ist too low for the drive");

}

}

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");
        }

     try  (kart.drive(2)
      if (kart.drive() == true){
      throw new IllegalArgumentException("The Karts battary ist too low for the drive");

    }
}

Is it possible that you need a catch block? I have not taken this module but I'm assuming that is part of the problem?

I am not familiar with the problem but a few things I notice right off the bat.

The try statement does not take any parameters so it would look like this.

try{
    logic goes here.
}

Also when you need to use a try block you need a catch statement to go with it. So your block of code would look something like this.

try{
    logic
}
catch (someException e){
    System.out.println(e.getMessage());
}

But the way you have the logic set up you are try to mash together two different exception handling techniques. The way I think that you are trying to make this work your code should 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");
        }

      if (kart.drive() == true){
          throw new IllegalArgumentException("The Karts battary ist too low for the drive");
    }
}

I am not amazing at explaining things clearly this link should help with differentiating between the two. https://docs.oracle.com/javase/tutorial/essential/exceptions/throwing.html

I hope this helps.
