what is the error?

Defined return type is Boolean. Not getting the error actually.

GoKart.java 
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount = 0;

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

  public String getColor() {
    return color;
  }

  public Boolean isBatteryEmpty(){

    return barCount==0;
  }


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

Your code looks perfect, ah wait... Almost perfect! Boolean is actually supposed to have a lowercase b. Replace your return type "Boolean" with boolean and you should be perfect!

Keep on coding!!!!

thanks a ton! been confused with the case sensitivity of the java. hey can you tell me is "Boolean" also a parameter in java or it was just in my mind(i think while calling a return or using in a constructor).

You could use a boolean value as a parameter. Let's say you had a method in a class called setRaining(boolean b) and now you could set it raining outside by passing in true or false as such: setRaining(true);

In most cases, you probably won't see anything like this until you start making far more complex stuff, But don't worry you will get there sooner then you think ;)

Keep up the great work!
