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

First of all you named the parameter that you pass into function the same way as 'lapsDriven' variable, it's nothing wrong with that but I think it can be a little bit confusing so let's name the parameter simply 'laps'. Than in the method you have to increase 'lapsDriven' variable by the amount that you passed in as parameter, and subtract 'barCount' by the same amount. 

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

Then for the second task in the first drive() method (the one that takes no parameters) you have to call the drive() method that you just create with 1 as parameter

public void drive() {
    drive(1);
}
