Java Java Objects Harnessing the Power of Objects Increment and Decrement

let's write a simple drive method. It should be public and not return anything. We'll call it GoKart drive a single lap.

In your newly created drive method, increment the new lapsDriven variable by 1. Use the incrementing shorthand to increase lapsDriven.

public void laps() { this.lapsDriven++;

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


  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.lapsDriven++;
    this.barCount--;
 }
 public void laps() {
   this.lapsDriven++;
}

The "laps" method seems to have unbalanced braces (missing a closing brace).

But I don't see anything in the instructions about creating a new "laps" method, so it shouldn't be there anyway.
