Modify the drive method to define a parameter of how many laps should be driven. Update the method body to handle the ne

I honestly don't even understand what this is asking me to do...? I feel like the exercise is super vague.

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

  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--;
    laps;
  }
}

Hi!

First, You need to accept a parameter to drive method, which represent the lap's number, so first the your drive method should seem like this:

public void drive(int laps) {

}

After it handle the new parameter, laps:

public void drive(int laps) {

lapsDriven += laps;

barCount -= laps;

}
