Is my code wrong?

I wrote a boolean expression. But it shows me Bummer! Whats wrong with my code? Please help.

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

  public void charge() {
    barCount = MAX_BARS;
  }
}

Your isBatteryEmpty() method never returns false. In order to get the function to work correctly you would need to do either one of the following:

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

or a simpler way to write the method would be...

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