在显示的JOptionPane一个数组中的内容（字符串） [英] Displaying the contents of an array (of strings) in JOptionPane

问题描述

我这里有一个要求输入并应在对话框中显示的字符串数组。三类

I have here three classes that asks for input and should display an array of strings in a dialog box.

第1类：

public class Card {

  public int rank;
  public int suit;
  public String rankName;
  public String suitName;
  public String cardName;

  public Card () {
    rank = 0;
    suit = 0;
    rankName = "";
    suitName = "";
    cardName = "";
  }

  public int getRank() {
    return rank;
  } 
  public void setRank(int rank) {
    this.rank = rank;
  }
  public int getSuit() {
    return suit;
  }
  public void setSuit(int suit) {
    this.suit = suit;
  }
  public String getRankName() {
    return rankName;
  }
  public void setRankName(String rankName) {
    this.rankName = rankName;
  }
  public String getSuitName() {
    return suitName;
  }
  public void setSuitName(String suitName) {
    this.suitName = suitName;
  }
  public String getCardName() {
    return cardName;
  }
  public void setCardName(String cardName) {
    this.cardName = cardName;
  }
}

2级 - 这是一流的，我应该输出我已经存储在数组中的字符串。我觉得我在正确的轨道做仿制药的一部分，但我不喜欢到，虽然。请指引我在打印所有这些。

Class 2 - this is the class where I should output the strings I have stored in an array. I think I'm on the right track doing generics part but I'm not fond to that though. Please guide me in printing all those.

import javax.swing.JOptionPane;

public class Deck {

    public void assignIntegerValues(Card card) {
        //Card card = new Card();
        String[] suitNameArray = {"Clubs", "Spades", "Hearts", "Diamonds"};
        String[] rankNameArray = {"Ace", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
        List<Card> cardName = new ArrayList();

        card.setSuitName  (suitNameArray[card.getSuit()-1]);
        card.setRankName (rankNameArray[card.getRank()-1]);
        card.setCardName (card.getSuitName() + "-" + card.getRankName());
        JOptionPane.showMessageDialog(null, card.cardName);
    }

    public void displayAll (Card card) {
        for (int i=0; i<card.cardName.length(); i++) {
            String print = JOptionPane.showMessageDialog(null, card.cardName[i]);
        }
    }
}

3类：

import javax.swing.JOptionPane;

public class DisplayDeck {

    public static void main(String[] args) {

        Card card = new Card();
        Deck deck = new Deck();
        int answer;
        String again;

        do {
            String suitString = JOptionPane.showInputDialog("Suit: ");
            card.setSuit (Integer.parseInt(suitString));

            String rankString = JOptionPane.showInputDialog("Rank: ");
            card.setRank (Integer.parseInt(rankString)); 

            deck.assignIntegerValues(card);
            String answerString = JOptionPane.showInputDialog("Try again? (1/0) ");
            answer = Integer.parseInt(answerString);
        } while (answer == 1);

        deck.displayAll(card);

    }
}

我想显示用户输入cardNames。

I'm trying to display the cardNames input by the user.

推荐答案

另一种方法取决于甲板有一个集合，每个新的卡添加

Another approach hinges on Deck having a collection to which each new Card is added:

class Deck {
    private List<Card> cards = new ArrayList<Card>();
    ...
}

是卡覆盖的toString（），

@Override
public String toString() {
    return cardName;
}

然后 displayAll（）变得非常简单：

public void displayAll() {
    JOptionPane.showMessageDialog(null,
        new JScrollPane(new JList(cards.toArray())));
}
