1.创建类

使用权限修饰符定义所需要参数，使用this关键字生成方法

public class gamejinhua {
private String suit;//花色

private int rank;//数字

public gamejinhua(String suit, int rank) {
this.suit = suit;

this.rank = rank;

}

2.使用快捷键生成get和set方法，作用是调取方法

public gamejinhua() {
// TODO Auto-generated constructor stub

}

public String getSuit() {
return suit;

}

public void setSuit(String suit) {
this.suit = suit;

}

public int getRank() {
return rank;

}

public void setRank(int rank) {
this.rank = rank;

}

3.传入花色

@Override

public String toString() {
return "{ "+suit+" "+rank+"}"; //重写toString方法，调用时产生花色与牌号

}

private static final String[] suits = {"♥","♣","♦","♠"};

4.创建list集合

public List<gamejinhua> takePoker(){
List<gamejinhua> pokers = new ArrayList<>();

for (int i = 0; i < 4; i++) { //外循环为4种花色

for (int j = 1; j <= 13; j++) { //内循环为A~K13张牌

gamejinhua poker = new gamejinhua(suits[i], j);

pokers.add(poker); //通过循环产生52张牌并放入集合中

}

}

return pokers;

5.使用random随机数生成打乱顺序

public void shuffle(List<gamejinhua> pokers){
for (int i = pokers.size()-1; i > 0; i--) {
Random random = new Random(); //用random随机函数打乱牌序

int index = random.nextInt(i);

swap(pokers,i,index);

}

}

6.调用方法

private void swap(List<gamejinhua> pokers, int i, int j){
gamejinhua tmp = pokers.get(i);

pokers.set(i,pokers.get(j)); //调用时，产生随机的花色和数字

pokers.set(j,tmp);

}

7.创建人的对象摸牌规则

public List<List<gamejinhua>> game(List<gamejinhua> pokers){
List<List<gamejinhua>> hand = new ArrayList<>();

List<gamejinhua> hand1 = new ArrayList<>();

List<gamejinhua> hand2 = new ArrayList<>();

List<gamejinhua> hand3 = new ArrayList<>();

hand.add(hand1);

hand.add(hand2); //三只手代表游戏的三个人

hand.add(hand3);

for (int i = 0; i < 5; i++) {
for (int j = 0; j < 3; j++) {
gamejinhua removePoker = pokers.remove(0); //循环控制三个人轮流摸牌，一人摸五张，一共15张

hand.get(j).add(removePoker);

}

}

return hand;

}

8.创建主函数并运行

public static void main(String[] args) {
gamejinhua game = new gamejinhua();

List<gamejinhua> pokers = game.takePoker();

System.out.println(pokers);

//洗牌

game.shuffle(pokers);

System.out.println("洗牌：");

System.out.println(pokers);

//揭牌

List<List<gamejinhua>> hand = game.game(pokers);

System.out.println("揭牌：");

for (int i = 0; i < hand.size(); i++) {
System.out.println("第 "+(i+1)+"个人的牌："+hand.get(i));

}

System.out.println("剩下的牌");

System.out.println(pokers);

}

}
