Actual and formal argument lists differ in length

Can't figure out what's wrong with this code. It says to create a GoKart object from the Go Kart class. Then it mentions something about the color parameter, but I'm not sure how to plug that in. It won't accept the getColor from the other GoKart.java file. What am I doing wrong?

Example.java 
public class Example {

    public static void main(String[] args) {
        System.out.println("We are going to create a GoKart");
      GoKart kart = new GoKart();
    }
}

Your kart looks great, except that it needs a formal parameter, the color. That's why you were getting that message. It wanted 1 parameter. You were sending none. Then you just need to print it out:

        GoKart kart = new GoKart("purple");
        System.out.printf("%s", kart.getColor());

With the creation of the constructor (in the last code challenge) we specified that an instance of the class "GoKart" needs to be instantiated with an String argument to be created. Like this:

GoKart kart = new GoKart("blue");

The String color goes in between those parenthesis.

I hope that helps a little bit.
