Double check you are calling the original drive method and passing in 1.

I'm getting this error message and am a little unsure how to remedy it. Any ideas amigos?

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() {
    drive(MAX_BARS);
  }

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

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

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

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

}

Instead of MAX_BARS, try using the value 1.

Perfect, thanks Craig :-)

first of all question says that takes no PARAMETER.. but then how do you overload if there is no parameter....
