LISTING 3.6 continued

cone3 = cone1;

System.out.println ();
System.out.println ("cone3 value: " + cone3);
System.out.println ("cone3 ordinal: " + cone3.ordinal());
System.out.println ("cone3 name: " + cone3.name());
}
}

OUTPUT

cone1 value: rockyRoad
cone1 ordinal: 5
cone1 name: rockyRoad

cone2 value: chocolate
cone2 ordinal: 1
cone2 name: chocolate

cone3 value: rockyRoad
cone3 ordinal: 5
cone3 name: rockyRoad

SELF-REVIEW QUESTIONS (see answers in Appendix N)
SR 3.29 Write the declaration of an enumerated type that represents movie ratings.
SR 3.30 Suppose that an enumerated type called CardSuit has been defined as
follows:

enum CardSuit {clubs, diamonds, hearts, spades}

What is the output of the following code sequence?

CardSuit card1, card2;
card1 = CardSuit.clubs;
card2 = CardSuit.hearts;
System.out.println (card1);
System.out.println (card2.name());
System.out.println (card1.ordinal());
System.out.println (card2.ordinal());

SR 3.31 Why use an enumerated type such as CardSuit defined in the previous
question? Why not just use String variables and assign them values
such as “hearts”?
