Create a helper method that returns whether or not the GoKart needs to be charged. Make it public and name it isBatteryE

I am confused about how to write a helper. Can anyone help me out?

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 charge() {
    mBarsCount = MAX_BARS;
  }
}

Because you created the barsCount variable, you have a way of determining whether the GoKart is charged. So, now you can create a method for the GoKart object that checks the value of the barsCount variable and returns true or false based on whether there are any bars. (It will use the same syntax as the other methods for the object; the "helper" wording doesn't really change anything).
