Question

我正在努力完成任务，目前难以解决我的问题。我已阅读了几篇文章并试图解决但没有成功。我知道我的很多代码都可以简化，但这是文本的进展所以很多东西还没有被覆盖......

这是我的卡类

import java.util.Random;

public class Card {
    private int suit,face;
    private String cardS,cardF;

    // Default constructor to generate random number for face and suit  
    public Card()
    {
        Random rand = new Random();
        suit = rand.nextInt(4)+1;
        face = rand.nextInt(13)+1;
    }

    // Receive card and suit values
    public Card(int cardSuit, int cardFace) {
        suit = cardSuit;
        face = cardFace;

    // Define card face and suit values

        if(suit == 1){
            cardS = "Clubs";            
        }
        else if(suit == 2){
            cardS = "Hearts";           
        }
        else if(suit == 3){
            cardS = "Spades";           
        }
        else if(suit == 4){
            cardS = "Diamonds";         
        }

        if(face == 1){
            cardF = "Ace";
        }
        else if(face == 2){
            cardF = "2";
        }
        else if(face == 3){
            cardF = "3";
        }
        else if(face == 4){
            cardF = "4";
        }
        else if(face == 5){
            cardF = "5";
        }
        else if(face == 6){
            cardF = "6";
        }
        else if(face == 7){
            cardF = "7";
        }
        else if(face == 8){
            cardF = "8";
        }
        else if(face == 9){
            cardF = "9";
        }
        else if(face == 10){
            cardF = "10";
        }
        else if(face == 11){
            cardF = "Jack";         
        }
        else if(face == 12){
            cardF = "Queen";
        }
        else if(face == 13){
            cardF = "King";
        }
        //return cardF + " of " + cardS;
    }

    // Get numerical face value
    public int getNumericFace(){
        return face;        
    }

    // Get numerical suit value
    public int getNumericSuit(){
        return suit;        
    }

}

这是我的DeckOfCards类

public class DeckOfCards {
    public static final int MAXDECK = 52;
    int remainingDeck,suit,face;
    String cardS,cardF;
    private int myCard;
    int cardIndex;
    Card[] cardDeck;
    public DeckOfCards() {


        cardDeck = new Card[MAXDECK];

        // Create array of 52 cards
        // outer loop cardSuit
        // inner loop cardFace
        int index = 0;
        int maxSuit = 4;
        int maxFace = 13;


        for (int cardSuit = 1 ; cardSuit <= maxSuit ; cardSuit++)
        {
            for (int cardFace = 1 ; cardFace <= maxFace ; cardFace++)
            {
                cardDeck[index] = new Card(cardSuit,cardFace);
                index++;
            }
        }
    }

    public String getArray()
    {   
        System.out.println(cardDeck[0]);
        for (int i = 0 ; i < cardDeck.length ; i++)
        {
            System.out.println(cardDeck[i]);
        }
        return "";
    }

    public String toString()
    {
        String deckAsString = "";
        int i=0;

        for (int s = 1; s <= 4 ; s++)
        {
            for (int c = 1 ; c <= 13 ; c++ )
            {
                deckAsString += (cardDeck[i] + "");
                i++;
            }
            deckAsString += "\n";
        }

        return (deckAsString);

    }   


}

这是我的主要课程......在这里运行这两种方法都存在问题。

public class MainDeck {

    public static void main(String[] args) {

        DeckOfCards game = new DeckOfCards();

        System.out.println("test getArray method");
        System.out.println(game.getArray());
        System.out.println("test toString method");
        System.out.println(game.toString());
    }

}

感谢您的帮助！

Answer 1

因为DeckOfCards中的toString方法正在使用cardDeck数组对象并将它们添加到返回的String中：

            deckAsString += (cardDeck[i] + "");

所以你需要覆盖toString类中的Card方法，并在字符串操作中使用它。

Answer 2

请在toString()课程中实施Card方法。

通过数组循环只打印classname @ hascode
