java - 为号码指定名称

Question

我目前正在编写一个涉及随机选牌的程序，我想知道是否有办法让程序分别用 jack 、皇后和国王替换数字 11、12 和 13？我可以使用 if 语句来检测大于 10 的值，但这会迫使我编写相同的代码大约 4 次，这似乎适得其反。非常感谢所有回复!

int card0 = (cardGenerator.nextInt(13) + 2);
        int winTest = 4;
        while(winTest > 0)
        {
            Object[] highLowEqual = { "higher", "lower", "equal", "Quit" };
            Object userChoice = JOptionPane.showInputDialog(null,
            "The current card is " + card0 + ". Which do you think the next card will be? Remember: Ace is the highest possible.", "HiLo",
            JOptionPane.INFORMATION_MESSAGE, null,
            highLowEqual, highLowEqual[0]);
            int card1 = (cardGenerator.nextInt(13) + 2);

有一个知道如何打印自身的 Card 类:

public class Card
{
    int rank; 

    // ...

    public String toString()
    {
        switch( rank )
        {
            case 1: return "Ace";
            case 2:
            case 3:
            case 4:
            case 5:
            case 6:
            case 7:
            case 8:
            case 9:
            case 10: return "" + rank;
            case 11: return "Jack";
            case 12: return "Queen";
            case 13: return "King";
            default: return "INVALID CARD RANK";
        }
    }
}
