Now change the color field to be private by adding the access level modifier.

public class GoKart {
  // the access level modifier is changed to private
  // now you can only access the mColor through the getColor method
  // This is called ENCAPSULATION and protects your variables
  private String mColor = "red";

  // this is a getter method that takes no arguments and returns the String "mColor"
  // before you created the getter your "mColor" wos public so evereone could access and use it
  // now you have the getter method to get the mColor variable through  calling the getter method
  // so it doesnt need to be public and can be changed to private
  public String getColor() {
   return mColor; 
  }
}
