Java Java Objects Harnessing the Power of Objects Increment and Decrement

Java Objects: drive Method / public / lapsDriven / variable of 1

Great! Now let's write a simple drive method. It should be public and not return anything. We'll start out basic, calling the drive method will make the GoKart drive a single lap.

In your newly created drive method, increment the new lapsDriven variable by 1. Use the incrementing shorthand to increase lapsDriven.

I'm stumped. I honestly don't know what to input next for this question. When I do make entries to what I think will work, the system comes back every time with "It looks like Task 1 is no longer passing."

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 barCount == 0;

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

  private int lapsDriven = 1; {


Hello, you need to create a valid method. Compare it with other methods, see the difference? You wrote something what is not correct:

private int lapsDriven = 1; {

Hi Tomas Svojanovsky

I now have private int lapsDriven; { }

What do I put next for the question above?
