First use an if statment to check if barCount is smaller then laps then throw the exeption inside the if statment. And don´t forget to insert the if statment before the variable declaration. And only change the provided code when it´s in the task^^

If you need help :)

--SPOILER--

lapsDriven += laps;
    barCount -= laps;
if(barCount < laps){
      throw new IllegalArgumentException("Not enough energy");
    }
