Another Java Problem :(

Here is the prompt:

Now that you've created the GoKart class. Please create a new GoKart object using the GoKart class, or blueprint. As you know it takes a single parameter, color when being built.

Here is the code of mine that does not work:

public class Example {

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

    public class GoKart {

        public GoKart(String color){

        }

    }


}

}

And just for reference, here is the code when you reset it to the start of the challenge:

public class Example {

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

}

Here is how you do it:

First off, you made a crucial mistake, the main method must be inside of a class.

class Main{

  public static void main(String[] args) {}

}

To create a GoKart class with a different constructor, you need to do:

class Main{

  public static void main(String[] args) {}
     GoKart a = new GoKart("red");
  }

He has main in class example.

So you are gonna want to use the GoKart kart = new GoKart('red"); declaration. <--- This declaration in the main method will create a new object reference and save it to the variable kart. The "new" keyword is what triggers the constructor on your GoKart class and gives the GoKart it's state from the color passed in the parameter.

You can delete the 

public class GoKart {

        public GoKart(String color){

        }

    }
