Hey Jhaycea,

you are painfully close :)

public class GoKart {
  private String mColor = "red";

  public GoKart (String color){ 

//  I changed mColor to GoKart
// this line declares a constructor and constructors name is the same as of the class

 mColor =  color; 
// here I changed Color to color 
// your constructor GoKart wants a String "color" as an argument not Color uppercased
// If you make a new object of the GoKart class like "GoKart goKart = new GoKart ("lemongreen")"
// "lemongreen" is your String argument you give to the constructor
// GoKart is like in real life a parent class, and you can have many GoKarts with different colors
// mColor = color is a way to encapsulate your private variables
// So you give something to your constructor (your color) and this String is equal to your private member variable mColor
  }

  public String getColor() {
    return mColor;
  }
}
