Says task one is no longer passing

I'm not sure what's wrong in my task 2 answer that's making it say that

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

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

  public String getColor() {
    return color;
  }

  public void charge() {
    barCount = MAX_BARS;
  }

  public boolean isBatteryEmpty() {
    if (barCount == 0) {
      return true;
    } else {
      return false;
    }

    public boolean isFullyCharged() {
      if (barCount == MAX_BARS) {
        return "Is fully charged!";
      } 
    }
  }
}

Just a few observations:

public boolean isFullyCharged() {
      if (barCount == MAX_BARS) {
        return "Is fully charged!";
      } 
    }

The method says "public boolean..." - meaning you would return either true or false. You're returning a string.

In this method:

public boolean isBatteryEmpty() {
    if (barCount == 0) {
      return true;
    } else {
      return false;
    }

It looks like your missing an "}"

Also instead of if/else you could just write:

return barCount == 0;

So - in total:

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

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