Question

I tried the following but got an error ‘wrong number of arguments (2 for 0)’:

class Rating
  NOOB = Rating.new(1, "U A NOOB")
  def initialize(rating, message)
    @rating = rating
    @message = message
  end
 end

What would be the equivalent of writing the following in Ruby? (this is my way of doing enums)

public class Rating {
  public static Rating NOOB = new Rating(1, "U SO NOOB");
  public static Rating EXPERT = new Rating(2, "U A PRO BRO");

  private int rating;
  private String message;

  public Rating(int rating, String message) {
    this.rating = rating;
    this.message = message;
  }
  ...
}

Answer 1

It works if you put

NOOB = Rating.new(1, "U A NOOB")

below the definition of initialize, as otherwise the interpreter hasn’t interpreted it, yet, and doesn’t know about the arguments it takes.
