need help

I'm stuck

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

  public boolean drive(){
    boolean waslapsDriven = false;
    if(! isEmpty()){
      lapsDriven = ++;
      was drive= true;

  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;

Here is your drive method with my comments

 public boolean drive(){
    boolean waslapsDriven = false;  // this line isn't needed
    if(! isEmpty()){   // there isn't a need for an if statment
      lapsDriven = ++; // to increment you need to do it like this: lapsDriven++;
      was drive= true; // this line isn't needed
     // here you need to add battery decrement:   barCount--;

did that answer help you ?? jose?
