Question

i even added a new class private int mLapsCount i just cant figure it out it stress me a lot i cant wait to have something really difficult ! thx guys in advance

GoKart.java

public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  private int mBarsCount; 
  private int mLapsCount;

  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 () {
    mLapsCount += 1 ;
  }

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

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

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

}

So the drive method should decrement, or decrease the value of mBarsCount by 1. So something like:

public void drive () {
    mLapsCount -= 1 ;
}

Or to tie the code into the drive method that already exists:

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

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

the first answer it says the same thing : the drive method should decrement the value of mBarsCount by 1 and the second answer it said: i should call the existing drive method and pass in the default parameter of 1, otherwise i have to rewrite all that (omitted) code thx for your support Rebecca and for answering fast i appreciate thx again :D
