567 PointsHow to declare without initializing?
Is the field declaration in the question referring to class or the constructor? In either case, how do I declare it without initializing with "red"? Am I to simply leave that space after the equals sign blank? I tried a combination of methods but to no avail. Please assist.
class GoKart {
private String color = "red";
public GoKart(String color) {
this.color = "red";
}
public String getColor() {
return color;
}
}

Try typing private String color in the global scope of the GoKart class which will declare the variable but not initialise it at that point.

567 PointsIt's slowly (very slowly) starting to make sense :) I managed to get pass the code challenge. Thanks again for your help!

567 PointsThanks for that prompt reply! I tried to do as you advised but I'm still getting a message that reads: "Whoops, color is still being assigned in the field declaration". Here's my updated code:
class GoKart { private String color;
public GoKart(String color) { this.color = "red"; }
public String getColor() { return color; }
}

Treehouse Moderator 91,253 PointsThere's one more thing I should have directed you to do. Sorry :)
In your constructor in task 2 you need to tell the constructor to set the value of
this.colorto the the value of your color variable, rather than hard coding the value red in the constructor. Basically, by the time the code challenge ends you won't have any reference to the colour red at all because later on you'll pass a value in when you instantiate your object.Hope this all makes sense :)
