Bummer! You need to create the isBatteryEmpty method.

I don't understand what's wrong the title is the message it's giving me. Please include code and explanation. Thanks in advance

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

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

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

  public String getColor() {
    return mColor;
  }

  public void charge() {
    mBarsCount = MAX_BARS;
  }  
}

You named your method mIsBatteryEmpty. Like the error suggests, the method must be named isBatteryEmpty. Try renaming it and see if it works!

You mistyped the method name, it is supposed to be isBatteryEmpty, you types mIsBatteryEmpty. Wrong spelling.

The isBatteryEmpty method is just a boolean. It would look like this: public boolean isBatteryEmpty() { return mBarsCount == 0; }
