what do i do?

Each lap around the track takes exactly 1 energy bar from the battery. For this final task, in your drive method, decrement the battery's status that we maintain in the private field barCount.

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

  public void drive() { 
    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(){
  lapsDriven++;
  barCount--;
}

Hey Braedon Angel 👋

It looks like you're missing a closing } to close your Class. After adding this your code is passing the challenge on my end 🙂
