How to Create a method that accepts no arguments and should call the method passing in a 1 for the default?

class GoKart {
  public static final int MAX_BARS = 8;
    private String color;
      private int barCount;
        private int lapsDriven;
          private int lapsCount;
  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 static drive() {

  }
    public void drive(int lapsNumber) {
        lapsDriven += lapsNumber;
          barCount -= lapsNumber;
          } 

}
