shorthanded to increment

the task asks the following:

In your newly created drive method, increment the new lapsDriven variable by 1. Use the incrementing shorthand to increase lapsDriven. and this is what I write but it says that its incorrect.

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

If someone can help me I would really appreciate it because I am stuck.

Thanks

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 charge() {
    barCount = MAX_BARS;
  }

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

  public boolean isFullyCharged() {
    return MAX_BARS == barCount;
  }
  public void drive() {
   lapsDriven +=1;
  }
}

While += 1 is a shorthand it is not the shortest way of increasing a variable. The shortest way is to use the increment operator ++ on the variable. Like this:

public void drive() {
   lapsDriven++;
}

That is the shorthand the task is looking for.
