I don't know what to delete from this code challenge, anything i do delete it comes back with an error. Plz Help

I read the question over and over trying to figure out what to delete, but I just cannot find it. Everything that I have deleted has either come back with an execution error or an incomplete error.

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

  public String getColor() {
    return color;
  }
  public GoKart(String color){
    this.color = color;
  }
}

Try making sure that your constructor is the first method.

class GoKart {

  private String color = "red";

  public GoKart(String color){
      this.color = color;
  }

  public String getColor() {
    return color;
  }

}

it's just asking you to not initialize the color, but only to declare it. a declaration is like String name;to initialize is to give a beginning value, whereas the declaration just creates the variable and it has no beginning value. so to initialize my name example, i could put name = "jon"; to do both in one line is what you have right now, like String name = "jon"; so just roll it back from an initialization to being just a declaration and it will pass.

At line 2 you are declaring the color ('private String color') and setting it to red (' = "red"'). Now that you have the correct constructor you want to set the color only in the constructor. Keep the part of line 2 where you declare the variable, and delete the part where you assign it to the value "red". Post you code here if you still have issues.
