如何遍历文本文件并每两行返回一个卡片对象？

因此，我有一个这样的文本文件格式，我试图将其转换为单张卡片并将它们放入数组中，并在下面放置了文本文件和类以向您展示我的所作所为：

a
h
2
h
3
h
4
h
5
h
6
h
7
h
8
h
9
h
t
h
j
h
q
h
k
h
a
d
2
d
3
d
4
d
5
d
6
d
7
d
8
d
9
d
t
d
j
d
q
d
k
d
a
c
2
c
3
c
4
c
5
c
6
c
7
c
8
c
9
c
t
c
j
c
q
c
k
c
a
s
2
s
3
s
4
s
5
s
6
s
7
s
8
s
9
s
t
s
j
s
q
s
k
s

因此，现在在注释的帮助下，我添加了以下类：

卡片：

public class Card {
    public String number;
    public String suit;

    public Card(String n, String s) {
        number = n;
        suit = s;
    }

    @Override
    public String toString() {
        return number + suit;
    }
}

和甲板（目前未完成）-

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;

public class Deck {
  private ArrayList < Card > cards;

  public Deck() {
    cards = new ArrayList < Card > ();
  }

  public List < Card > buildDeck() throws IOException {

    List < String > cardLines = Files.readAllLines(Paths.get("cards.txt"));

    // build card objects
    List < Card > result = new ArrayList < Card > ();
    for (int i = 0; i < cardLines.size(); i += 2) { //if lines read are smaller than file then read for another card
      cards.add(new Card(cardLines.get(i), cardLines.get(i + 1))); //add new card to cards array
    }
    return result;
  }

  /*public void shuffle() {
        // fill in
    }*/

}

这将是我的GUI类-

import java.util.Scanner;

public class Game {
  public Scanner scan;

  public void runMenu() {
    String response;
    do {
      printMenu();
      System.out.println("What would you like to do:");
      scan = new Scanner(System.in);
      response = scan.nextLine().toUpperCase();
      switch (response) {
        case "1":
          buildDeck();
          break;
        case "2":
          ShuffleCards();
          break;
        case "3":
          DealCard();
          break;
        case "4":
          MoveToPrevious();
          break;
        case "5":
          Move2PilesBack();
          break;
        case "6":
          AmalgamateInMiddle();
          break;
        case "7":
          PlayforMe();
          break;
        case "8":
          ShowLowScores();
        case "Q":
          break;
        default:
          System.out.println("Try again");
      }
    } while (!(response.equals("Q")));
  }

  private void ShowLowScores() {
    // TODO Auto-generated method stub
  }

  private void PlayforMe() {
    // TODO Auto-generated method stub
  }

  private void AmalgamateInMiddle() {
    // TODO Auto-generated method stub
  }

  private void Move2PilesBack() {
    // TODO Auto-generated method stub
  }

  private void MoveToPrevious() {
    // TODO Auto-generated method stub
  }

  private void DealCard() {
    // TODO Auto-generated method stub
  }

  private void ShuffleCards() {
    // TODO Auto-generated method stub
  }

  private void buildDeck() {
    // TODO Auto-generated method stub
  }

  private void printMenu() {
    System.out.println("1 -  Print the pack ");
    System.out.println("2 -  Shuffle");
    System.out.println("3 -  Deal a card");
    System.out.println("4 -  Move last pile onto previous one");
    System.out.println("5 -  Move last pile back over two piles");
    System.out.println("6 -  Amalgamate piles in the middle");
    System.out.println("7 -  Play for me");
    System.out.println("8 -  Show low scores");
    System.out.println("q - Quit");
  }
}

因此，在我的其他错误现在似乎已得到解决，并且已经通过注释获得了帮助之后，如何将卡座类中的arraylist打印到我的GUI类选项1中，谢谢！
