I thought for sure I was right but clearly I am not.

Really don't know what to do more with this.

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

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

  public String getColor() {
    return mColor;
  }

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

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

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

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

}

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

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

  public String getColor() {
    return mColor;
  }

  public void drive(int laps) {

    // to start this method 

    mBarsCount -= laps;
  }

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

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

  public boolean isFullyCharged() {
    return mBarsCount == MAX_BARS;
  }
  public void drive() {
    // we use this
    drive(1);
  }

}

Important to know is just:

  public void drive(int laps) {

    // ....to start this method 
    // to do this "lap-thing"
    mBarsCount -= laps;
  }

  public void drive() {
    // we use this....
    // starts the drive methods with the argument and give it "1" as an argument
    drive(1);
  }

Thank you, Tobias. But that is not at all what I learned in the video.

Your answer was great. But why does he drone on in the pez video thing about something entirely different, if that is not what we are going to do in the exercise?
