To instantiate (create a new instance of) an object in Java you will need to use the following syntax.

ClassName yourObjectName = new ClassName()

So, to create a new GoKart you could do the following!

GoKart newGoKart = new GoKart()

I hope that this helps!

I think you should declare the new "GoKart" in the main method;

Like that:

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

}

I hope that this helps!

I have already added the new keyword and all of that but it keeps sendind me the same error here is the code:

public class Example {

public static class GoKart{ private String mColor;

public GoKart(String karColor){
  mColor = karColor;
}
public String getKartColor(){
  return mColor; 
}

}
public static void main(String[] args) { System.out.println("We are going to create a GoKart"); GoKart newGoKart = new GoKart(" New Red"); System.out.printf("The newGoKart color is %s\n", newGoKart.getKartColor()); } }

public class Example {

public static class GoKart{

private String mColor;

public GoKart(String karColor){

  mColor = karColor;

}

public String getKartColor(){

  return mColor; 

}

}

public static void main(String[] args) {

    System.out.println("We are going to create a GoKart");

    GoKart newGoKart = new GoKart(" New Red");

      System.out.printf("The newGoKart color is %s\n",

                        newGoKart.getKartColor());

}

}

Just work in the main method, looks like you embedded the GoKart class. You don't need it in this file.

Sorry for the confusion!

Thank you Craig, https://teamtreehouse.com/library/java-objects-retired/meet-objects/creating-new-objects

This challenge was the most difficult for me. But it maybe more true to life, because the stated requirements and or previous challenge requirements we as developers will always have to deal with it.

I included the challenge code that worked for me... Thanks, -fred

public class Example {

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

    GoKart color = new GoKart("red");
    System.out.printf("The color of the GoKart is %s\n",
                      color.getColor());

}

/*
public class GoKart { private String mColor = "red"; //GoKart gokart = new GoKart(mColor); // GoKart object

public GoKart(String color) { mColor = color; }

public String getColor() { return mColor; } } */ }
