Question

I do not understand this task.

GoKart.java

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

  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;
  }

  public void drive() {
    lapsDriven++;
    barCount--;
  }

  public void drive (int lapsShouldBeDriven) {
   lapsDriven += lapsShouldBeDriven;
   barCount -= lapsShouldBeDriven;
  }

}

Hi Tomasz

You almost made it. You just need to modify your code a little. The last task of the challenge just want you to create another drive method without passing any parameters and call the previous drive method which required an integer as parameter and give that integer the value of 1. Here is the revision will look like:

 public void drive() {
    /*You do not need this anymore:
    lapsDriven++;
    barCount--;*/
    //you just need to call the method drive(int lapsShouldBeDriven) and pass 1 as parameter value like this:
    drive(1);
  }

  public void drive (int lapsShouldBeDriven) {
   lapsDriven += lapsShouldBeDriven;
   barCount -= lapsShouldBeDriven;
  }

There you go, I hope this can help.
