Using enums in Java across multiple classes

Question

I have the following class:

public class Card  {     public enum Suit      {         SPACES, HEARTS, DIAMONDS, CLUBS     };      public Card(Suit nsuit, int nrank)     {         suit = nsuit;         rank = nrank;     }      private Suit suit;     private int rank; } 

I want to instantiate it in another class, but that class doesn't understand the Suit enum. Where should I put the enum to make it publicly visible?

Answer 1

The Suit enum is inside the Card class, and you have to access it that way:

new Card(Card.Suit.SPADES, 1); 

Or, you can import the Suit class from within Card, and access it directly:

import my.package.Card.Suit; new Card(Suit.SPADES, 1); 

The other option is to put Suit in its own class, as suggested by Bert.
