Java Java Objects Harnessing the Power of Objects Overload Methods

How to pass in 1 as a default for my method overload?

I'm not understanding this question correctly. It never said for me to delete my old drive method(), it wanted me to create a new drive method with no parameters? And add a method passing 1 for the default?

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 void drive() {
    lapsDriven = 1;
  }
  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 lapsDrivenIn){
    lapsDriven += lapsDrivenIn;
    barCount -= lapsDrivenIn;
    }


}

Your code technically does the right thing, but not in the way the challenge asked for.

When they say, "It should call the newer drive method passing in a 1 for the default.", they mean instead of making changes to the variables directly, just call the other version of "drive" (the one that now takes an argument) and give it the value 1 as the argument.

Ahh I didn't know you can just throw the value into the method without declaring variables.
