Java OCA OCP Practice Question 3098

Question

Consider the following enumeration definition: 

enum Cards { CLUB, SPADE, DIAMOND, HEARTS };

public class Main {
        public static void main(String []args) {
               /* TRAVERSE */
        }
}

Which one of the following will you replace in place of the comment /* TRAVERSE */ to traverse the Cards enumeration and print the output "CLUB SPADE DIAMOND HEARTS"?. 

a) for(Cards card : Cards.values())
       System.out.print(card + " ");
b) for(Cards card : Cards.iterator())
       System.out.print(card + " ");
c) for(Cards card : Cards.enums())
       System.out.print(card + " ");
d) for(Cards card : Cards.items())
       System.out.print(card + " ");
e) There is no way to print the string names of this enumeration.
   The toString() method of enumeration returns the
   ordinal value of the enumeration, which is equivalent to 
   calling card.ordinal().toString();./*from   www. jav a2 s  . c om*/



a)

Note

The values() method of an enumeration returns the array of enumeration members.
