I have added the drive method, I am not recalling how to increment using shorthand. May I have a little assistance?

I am on Challenge Task 2 of 3 for the Increment and Decrement lesson. I have added the drive method. After that, it is asking to use short hand to increase the "lapsDriven" by 1 each time around the track. I am not recalling how to do this after watching the lesson.

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 String getColor() {
    return color;
  }

  public void drive()   {
    lapsDriven = 1;
  }

  public void charge() {
    barCount = MAX_BARS;
  }

  public boolean isBatteryEmpty() {
    return barCount == 0;
  }

  public boolean isFullyCharged() {
    return MAX_BARS == barCount;
  }
}

You should be able to do lapsDriven += 1 or lapsDriven++

I'd do lapsDriven +=1 but yes.
