Question

I want to display different string array elements like this:

• Clubs 1
• Hearts Ace
• Diamonds 9

CardGame.java:

public class CardGame {
    public static void main(String[] args){
        String[] suit = { "Clubs", "Hearts", "Diamonds", "Spades" };
        String[] deck = { "2", "3", "4", "5", "6", "7", "8", "9", "10",
                        "Jack", "Queen", "King", "Aces" };

        int i = (int) ( Math.random() * deck.length );
        int j = (int) ( Math.random() * suit.length );


        for( int a = 0; a < 7; a++ ) {
            System.out.println( "Deck " + deck[i] + " Suit " + suit[j] );
        }

        System.out.println();
    }
}

How will I do it? Point me to correct logic of displaying those different elements. Thanks.

Answer 1

    int times = 10; // Say you want it 10 times, in your code it's 7.

    for (int i = 0; i < times; i++) {
        System.out.println(deck[(int) (Math.random() * deck.length)]
                 + " : " + suit[(int) (Math.random() * suit.length)]);
    }
