it said "Oops! It looks like Task 1 is no longer passing." why ?

i already follow the instruction , but why it keep showing "Oops! It looks like Task 1 is no longer passing"

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

  public void boolean drive(){
  lapsDriven += 1;
  }

  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;
  }
}

Hi Herry,

Let's first look at the question in the code challenge.

First,

You're asked to create a new private int field named lapsDriven, as you've done.

The problem starts in your drive method. You're trying return a boolean data type where none is needed. It's also asking you to use the post increment shorthand operator which is ++. The same as writing lapsDriven = lapsDriven + 1;

  public void drive(){
  lapsDriven++;
  }

Finally you'll need to decrement the barCount private int field in the same way, in the same method. Hope this helps :)
