Overload method question 2

HI guys im stuck on question two of the overloading method exercise. Does anyone have the answers?

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()
{
  this.drive=1;
}
  public void drive(int laps) {
    lapsDriven+=laps;
    barCount-=laps;
    lapsDriven++;
    barCount--;
  }
}

Seems like this one is a pretty common cause for confusion. Check out my answer to a similar question on the same code challenge.

Hi! I haven't done this exercise yet, but if I understand it correctly, you are to use the method drive(int laps) from within your method drive(), that is, use a call to the drive method with a int parameter from the method without any parameters. So you will have to pass it a suitable integer for what you want to accomplish. Does it make sense?

Good luck!

THX for the help guys. My confusion was at the pass a 1. All I had to do was put the code fill(lapsDriven =1) inside of the new fill method . Also in Craigs video he used MAX_PEZ which was the equivalent to the MAX_BARS in this exercise so I got really confused.
