  public static final int MAX_BARS = 8;
  private String mColor;

  public int laps = 1;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }

  public String getColor() {
    return mColor;
  }

  public void drive(int laps) {
    // Other driving code omitted for clarity purposes
    mBarsCount -= laps;
  }
  public void drive(int i){
    i = laps;
  }

  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }

  public boolean isBatteryEmpty() {
    return mBarsCount == 0;

'''java public void drive(int i){ i = laps; } ''' you have added the method i pasted above. but it is already in your code so you cannot overload the constructor . you should delete the method you have added and then add another constructor like this. '''java public void drive(){ drive(1); } ''' so that when there are no arguments added, the constructor without parameters is executed and calls the constructor with an integer parameter.

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