now create a helper method

aren't I suppose to do this on the other class?

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

  public String getColor() {
    return mColor;
  }

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

In this challenge, it wants you to write a method that will check to see if the GoKart has no battery charge left.

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

What this will do is check to see if the mBarsCount (the current charge) is equal to 0. If it is, it will return true, otherwise it will return false.

The next part of the challenge is very similar to this one, it just requires you to compare to MAX_BARS.

Hope that helps!
