Question

JAVA

Hello I have built two enum classes . Pics attached.

را اراده ج دا ما ها هم اليها و دے ، می داد که ما ده Files 4 package unocardgame; Projects public enum CardType { ZERO ("Zero", 0), ONE ("One", l), TWO("Two",2), THREE ("Three", 3), FOUR("Four", 4), FIVE ("Five",5), SIX("Five",5), SEVEN("Five",5), EIGHT("Five",5), NINE ("Five",5), SKIP("SKIP",0), REVERSE ("Reverse",0), DRAW 2 ("Draw2",0), DRAW 4 ("Draw4",0), WILD("Wild", 4),; String Name; int Number; CardType (String name, int num) { Name = name; Number = num;

How can I create a list of cards from these classes .. shuffle them.. and draw 7 cards at a time

ArrayList<Card> Cards;

Answer 1

For this, we need to create the Card class as below:

public class Card {
    CardType cardType;      // card type
    Color color;            // card color

    // constructor
    public Card(CardType cardType, Color color) {
        this.cardType = cardType;
        this.color = color;
    }
}

This class has card type and color.

Now, to declare the list of cards, we can do like below code in your main method:

public static void main(String[] args) {
        // declare the list of Card objects
        ArrayList<Card> Cards = new ArrayList<>();

        // fill the ArrayList as per the requirement
        Cards.add(new Card(CardType.THREE, Color.YELLOW));
        Cards.add(new Card(CardType.DRAW2, Color.BLUE));
        Cards.add(new Card(CardType.FIVE, Color.RED));
        Cards.add(new Card(CardType.FIVE, Color.GREEN));
        Cards.add(new Card(CardType.NINE, Color.GREEN));
        Cards.add(new Card(CardType.ONE, Color.YELLOW));
        Cards.add(new Card(CardType.WILD, Color.GREEN));
        Cards.add(new Card(CardType.ZERO, Color.RED));
        Cards.add(new Card(CardType.REVERSE, Color.BLUE));
        Cards.add(new Card(CardType.DRAW4, Color.RED));

        // shuffle the list
        Collections.shuffle(Cards);

        // create a list for hand of 7 cards
        ArrayList<Card> hand = new ArrayList<>();

        // draw 7 cards in hand, after this loop hand will have the
        // 7 cards drawn from shuffled list
        for (int i = 0; i < 7; i++) {
            hand.add(Cards.get(i));
        }
    }

This completes the requirement. Let me know if you have any questions.

Thanks!
