The Challenge Task is asking me to create a public method called IsBatteryEmpty, which I did. Still getting an error.

It is supposed to return true or false,

GoKart.java 
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;

  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }

  public boolean IsBatteryEmpty(int barCount) {
    if(barCount == 0)
      return true;
    else return false;
  }

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

Hi Jamal. What is the error you're getting?

I see a couple things that you could try updating. One would be to add brackets to the method. An example found here: https://www.learnjavaonline.org/en/Conditionals Also I don't think that IsBatteryEmpty needs parameters.

Becky Hirsch is right about not needing parameters. The other problem is that it wants isBatteryEmpty rather than IsBatteryEmpty.

To consolidate the two above answers, your method name should start with a lowercase letter. And rather than passing barCount in as a parameter, you should be comparing "this.barCount", because the method you are writing has access to the barCount variable.
