Question

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) {
    // Other driving code omitted for clarity purposes
    mBarsCount -= laps;
  }
  public void drive(GoKart laps, 1) {
    drive(laps, 1);
    mBarsCOunt -= 1;
  }
  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }
  public boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }
  public boolean isFullyCharged() {
    return mBarsCount == MAX_BARS;
  }
}
I am not getting what is wrong in 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(int laps) {
    // Other driving code omitted for clarity purposes
    mBarsCount -= laps;
  }
  public void drive(GoKart laps, 1) {
    drive(laps, 1);
    mBarsCOunt -= 1;
  }
  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }
  public boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }
  public boolean isFullyCharged() {
    return mBarsCount == MAX_BARS;
  }
}
```

Thank you so much

Hi,
You need to have following code:
public void drive(){
   drive(1);
}
You don't need to pass GoKart object into this method. Both methods are contained in GoKart class.
