Java Java Objects Harnessing the Power of Objects Throwing Exceptions

Please, a little hint. 'new IllegalArgumentException'

Thanks!

GoKart.java
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;
  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 (lapsDriven > MAX_BARS) {
      throw new IllegalArgumentException("Too  many laps");
    }
  }
}

Hi Miguel,

right now you are checking if the laps that have been driven are greater than the constant of maximum battery bars the GoKart can have.

You want to check if the laps that have been passed into the drive function are greater than the barCount.

Kind Regards, Florian

I get it. Thanks a lot, Florian.
