No idea where to start

Can I get a hint on where I should start? I have no clue...

Example.java 
public class Example {

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

Hi Jimmy,

to create a new instance of the class is the same as creating a new object of that class.

So do it like this:

Here we are creating a new instance of the GoKart class:

GoKart nameOfYourChoise = new Gokart();
// new creates a new instance, we call it instantiation
// inside the parethesis you can put arguments
// that are defined inside your constructor

Does it make sense?

Thank you for the help! But I still do not understand.

I'm not sure what an instance is either. So "GoKart" /*without the quotes */ creates the new class? and the parenthesis makes the parameter right? so what is the quiz asking for?

this is what i end up with.... public class Example {

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

GoKart Vroom = new Gokart (); } }

but i'm still getting an error : ./Example.java:5: error: cannot find symbol GoKart Vroom = new Gokart (); } ^ symbol: class Gokart location: class Example 1 error

Hey there :)

public class Example {

    public static void main(String[] args) {
        System.out.println("We are going to create a GoKart");
      // TASK 1  
      GoKart nameOfYourChoise = new GoKart("red");
          // nameOfYourChoise ist the name of the object (same as instance) of the GoKart class
          // inside the () you need place a parameter
          // this parameter is color and it is a String
          // Strings use "" and characters
          // so you can type "red"

      // TASK 2
      System.out.printf("The color of the GoKart object is %s", nameOfYourChoise.getColor());
          // our GoKart class is a blueprint for all object we create through the line above
          // inside the blueprint you can define methods to get the color or do something else
          // to use the methods of the GoKart class (our blueprint) we need the name of our newly created object
          // the dot operator (.) and the getColor() method name
          // so where we place our %s, there will be the color we gave to the nameOfYourChoise object 
    }
}

Does it make sense?
