java - 编写 CardTrick 程序，我无法确定用户的卡是否是从一副牌中随机抽取的七张卡中的一张

Question

有关代码的所有内容都工作正常，直到我在 Cardtrick 类中添加最后一个 If 语句以查看用户卡片选择是否与七张随机卡片匹配。当我不运行 If 语句时，代码按我的预期工作，我看到 7 张随机卡。我添加了 Card 类，以防万一你们想看它。

`package pickacard;

import java.util.Scanner;

public class CardTrick {

    public static void main(String[] args){
                Scanner input = new Scanner(System.in);
        Card[] magicHand = new Card[7];

        for (int i=0; i<magicHand.length; i++){

            Card c = new Card();

    c.setValue(c.randomValue());
    c.setSuit(Card.SUITS[c.randomSuit()]);
    magicHand[i] =c;
        }

        for (Card magicHand1 : magicHand) {
            System.out.println(magicHand1.getSuit() + " " + magicHand1.getValue());
        }
         System.out.println("Pick a card, any card");
        System.out.println("Pick the card value");

      int UserValue = input.nextInt();
        System.out.println("Pick the card suit");
                System.out.println("1 = Hearts, 2 = Diamonds, 3 = Spades, 4 = Clubs");

        int UserSuit = input.nextInt();

        System.out.println("Your card is: " + UserValue + " of " + UserSuit);
                System.out.println("Let's see if your card is in the magic hand");

    if(UserValue== magicHand1.getValue() && UserSuit == magicHand1()){
    System.out.println("Great job");
     }
      }
      }

Answer 1

&& UserSuit == magicHand1()

这是将 int 与 Card 进行比较。您可能想检查 magicHand1.getSuit() 的值，但您需要确保用户输入已转换为您用于 suit< 的字符串之一.
