本文例項為大家分享了Java實現撲克牌洗牌發牌的具體程式碼，供大家參考，具體內容如下

實現原理：使用4種花色和13個數字組合成52張牌，放進一個集合中；通過把集合資料排序打亂實現洗牌操作，然後在通過迴圈把牌抽出來實現發牌操作。

下面是實現程式碼：

import java.util.ArrayList;
import java.util.Collections;

public class Card {
  private static ArrayList<String> list = new ArrayList<>();
  private static String[] colors = {"黑桃","紅桃","梅花","方塊"};
  private static String[] nums = {"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
  private static String[] jokers = {"Joker","joker"}; //大小王
  private static ArrayList<String> A = new ArrayList<>(); //小人A
  private static ArrayList<String> B = new ArrayList<>(); //小人B
  private static ArrayList<String> C = new ArrayList<>(); //小人C
  private static ArrayList<String> D = new ArrayList<>(); //小人D

  //初始化撲克牌
  public static void initCards(boolean need){
    for(String color:colors){
      for (String num:nums) {
        list.add(color + num);
      }
    }
    //是否新增大小王
    if (need) {
      list.add(jokers[0]);
      list.add(jokers[1]);
    }
  }

  //洗牌
  public static void xiPai(){
    Collections.shuffle(list);
  }

  //性感荷官，線上發牌
  public static void faPai(){
    A.clear();
    B.clear();
    C.clear();
    D.clear();
    for (int i = 0; i < list.size();i++) {
      if (i%4 == 0) {
        A.add(list.get(i));
      }
      if (i%4 == 1) {
        B.add(list.get(i));
      }
      if (i%4 == 2) {
        C.add(list.get(i));
      }
      if (i%4 == 3) {
        D.add(list.get(i));
      }
    }
  }

  //主方法
  public static void main(String args[]){
    initCards(true);
    xiPai();
    faPai();
    System.out.print("小人A" + A + "\n");
    System.out.print("小人B" + B + "\n");
    System.out.print("小人C" + C + "\n");
    System.out.print("小人D" + D + "\n");
  }
}

下面是執行結果
