What does "passing in a 1" mean? i am absolutely unfamiliar to this therm, how should i call this method?

I do not understand what he means by "passing in a 1", which makes it impossible to complete the task...

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(int lapsRollin) {
    lapsDriven += lapsRollin;
    barCount -= lapsRollin;

  public void drive() {

When they say "passing in" they mean "supplying as the argument".

So if you are "passing in a 1" then when you invoke the function, you would have a 1 in parentheses following the function name.
