Finally, since the color is being set in the constructor now, remove the initialization from the field definition. Just leave it declared, but not initialized to "red".

I have absolutely no idea what this means. What is meant by "field", "initialization" and "declared"?

GoKart.java 
class GoKart {
  private String color = "red";

  //constructor
  public GoKart(String color){
    this.color = "red";
  }

  public String getColor(){
    return color;
  }

}

Thank you for the answer Fahad. I changed private String color = "red"; to private String color;

but it still says color is still being assigned in the field declaration...?

  }

  public String getColor(){

Hey for anyone looking for help in 2020, here it goes. Just developing on Fahad's point:

You need to change the initial answer of: private String color = "red";

In the second line to -

private String color = "color";

Hope that helps.
