Question

在我的程序中能够向玩家交易5张随机牌，但我想知道如何在我的程序中加入一个套牌洗牌，因为在我的随机化方式中我倾向于最终使用重复的卡

import java.util.Scanner;

public class Prog2d {

    public static void main(String[] args) 
    {

        Scanner in = new Scanner(System.in);
        int userChoice;
        String[] suit = {"Clubs","Diamonds","Hearts","Spades"};
        String[] faces = {"2","3","4","5","6","7","8","9","10","Jack","King","Queen","Ace"};
        String[][] deck = new String[faces.length][suit.length];


        System.out.println("Program 2d, Christian Villa, masc1854");

        userChoice = in.nextInt();

        while(userChoice > 0)
        {


           for(int k = 0; k < 5;k++)
                {
                   int i = (int)(Math.random()*suit.length);
                   int j = (int)(Math.random()*faces.length);

                   System.out.println(faces[j] + " of " + suit[i]);
                }
                 userChoice--;
               System.out.println();
        }

    }

}

您可以先使用Collections.shuffle数组进行随机播放，然后在不使用Math.random方法的情况下进行迭代：

while(userChoice > 0)
    {

       Collections.shuffle(Arrays.asList(suit));
       Collections.shuffle(Arrays.asList(faces));
       for(int k = 0; k > 4;k++)
            {
               System.out.println(faces[k] + " of " + suit[k]);
            }
             userChoice--;
           System.out.println();
    }
