i don't understand the increment question.

i am confused about passing the lapsDriven and the drive method in general , the question isn't clear to me.

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

  drive();


  public String drive(){
    lapsDriven=lapsDriven+1;
  }

  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;
  }
}

The challenge wants you to create a method that doesn't return anything, you created one that returns a string. It also wanted you to use the shorthand increment operator:

public void drive(){
    lapsDriven++;
}

Make sure you don't have drive(); in your code anywhere. I see it in your code snippet just below the class properties.
