    String str = "";
    String[] face = { "♥", "♠", "♣", "♦" };
    String[] number = { "A", "2", "3", "4", "5", "6", "7", "8", "9", "10",
        "J", "Q", "K" };
    str += face[num % 4] + number[num % 13];
    return str;
  }
  public void shuffle(@SuppressWarnings("rawtypes") ArrayList list) {
  }
  @SuppressWarnings("unchecked")
  public static void main(String[] args) {
    @SuppressWarnings("rawtypes")
    ArrayList list = new ArrayList();
    Card card = new Card();
    for (int i = 0; i < 52; i++) {
      list.add(card.poker(i));
    }
    for (int i = 0; i < list.size(); i++) {
      System.out.printf("%s\t", list.get(i));
      if ((i + 1) % 13 == 0) {
        System.out.println(" ");
      }
    }
    System.out.println();
    Collections.shuffle(list);
    System.out.println("洗牌后:");
    for (int i = 0; i < list.size(); i++) {
      System.out.printf("%s\t", list.get(i));
      if ((i + 1) % 13 == 0) {
        System.out.println(" ");
      }
    }
  }
}

输出:
