Question

I'm stuck

Example.java

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 laps){
      System.out.println("You don't have enough charge", laps.getMessage());
    }

  }

}

GoKart.java

class GoKart {
  public static final int MAX_BARS = 8;
  private int barCount;
  private String color;
  private int lapsDriven;

  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }

  public void charge() {
    barCount = MAX_BARS;
  }

  public boolean isBatteryEmpty() {
    return barCount == 0;
  }

  public boolean isFullyCharged() {
    return MAX_BARS == barCount;
  }

  public void drive() {
    drive(1);
  }

  public void drive(int laps) {
    if (laps > barCount) {
      throw new IllegalArgumentException("Not enough battery remains");
    }
    lapsDriven += laps;
    barCount -= laps;
  }

}

You are pretty close, in the exception handler, it looks like you were trying to call a println method with 2 parameters which doesn't exist. In this case you just need to print the message from the exception:

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 laps){
      System.out.println(laps.getMessage());
    }
  }
}
