Create a new public method named isBatteryEmpty that returns true if the battery has 0 bars remaining, and else false

I have a problem with my code....

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() {
    return true;
  }
}

Your isBatteryEmpty() method is always returning true. Use an if statement to return true only if barCount is zero; otherwise return false.

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