constructor GoKart in class GoKart cannot be applied to given types

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();
System.out.printf("The GoKart color is %s\n",
                  kart.getColor());
    }
}

gives the following error:

Any idea what's wrong?

Sebastiaan;

Welcome to Treehouse!

You are missing something in your kart creation line. If you recall from the course, and from the Task 1 instructions, when we create a new kart with new GoKart(), we need to input a parameter of type String. Conceptually this would be the color of the GoKart we are creating. So we could do something like:

GoKart blueKart = new GoKart("blue");

Since you left out a color parameter in your item creation, it will give the above error.

Post back if you are still stuck.

Happy coding,
Ken
