./Example.java:2: error: '{' expected public class GoKart (color) {} ^ 1 error

I don't understand what the question is entirely asking?

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

Welcome to Treehouse!

Task 1 of this challenge asks:

Please create a new GoKart object. As you know it takes a single parameter, color.

There's a couple of steps to thing about as we walk through this task. In Java the way we create a new object, based on a GenericClassName name would be:

GenericClassName objectName = new GenericClassName();

For this challenge we are creating a new object based on our GoKart class model, so we would code that as:

GoKart someObjectName = new GoKart();

The second portion of the challenge task reminds us that our GoKarts need a specific color assigned to them. We can do that when we create the object by:

GoKart someObjectName = new GoKart("green");

Viola! We now have a new GoKart that is green in color named someObjectName. That will pass the challenge just fine, but think about maintaining your code later on, or passing your code on to someone else to maintain. Does someObjectName really mean anything? You may know exactly what it means going through the challenge today, but what about in 6 weeks? Let's, therefore, be nice to ourselves and the other folks looking at our code and do something like:

GoKart greenKart = new GoKart("green");

That will make it more obvious when you are looking at your code what a greenKart is, and will put a :smile: on the faces of folks later on.

I hope that helps. Please post back if it does not.

Happy coding,
