Can someone please help me figure out what's wrong?

This is what I have to do: You probably already spotted the error in the drive method that accepts laps. You can drive way more laps than our battery can handle. Let's fix it.

Add logic to the drive method so that it throws an IllegalArgumentException if there aren't enough bars to support the laps request. Remember it takes 1 bar of energy to go around a lap.

Please try to help me out with this! I await anyone's response!

My code so far:

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) { int totalLaps = lapsDriven += laps; if (totalLaps > MAX_BARS) { throw new IllegalArgumentException("You cannot drive this much!"); } barCount = laps; } }

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) {
    int totalLaps = lapsDriven += laps;
    if (totalLaps > MAX_BARS) {
      throw new IllegalArgumentException("You cannot drive this much!");
    }
    barCount = laps;
  }
}
