有没有大佬帮我看看，我这个斗地主，为什么不自动整理牌？？？

仔细检查你的看牌方法

[ぃ坠花湮゛]

System.out.println("小花："+ kanpoker(xiaohua,pokers)); System.out.println("小黑："+kanpoker（xiaohei，pokers)); System.out.println("小王:"+kanpoker（xiaowang，pokers)); System.out.println("底牌："+kanpoker（dipai，pokers)); 正确之后 还是不能正确排序

[起名伤脑]

sort直接排序是有问题的，你的"10", "J", "Q", "K", "A"排出来的顺序肯定是不对的

引用 2 楼 ぃ坠花湮゛ 的回复:

System.out.println("小花："+ kanpoker(xiaohua,pokers)); System.out.println("小黑："+kanpoker（xiaohei，pokers)); System.out.println("小王:"+kanpoker（xiaowang，pokers)); System.out.println("底牌："+kanpoker（dipai，pokers)); 正确之后 还是不能正确排序

你写的一些符号有中文符号！

我将代码整理优化了一下，你可以看看：https://www.cnblogs.com/li-chuan/articles/14681412.html

排序没有问题，是你用嵌套循环生成排序的时候放反了。你把shuzi 套在 huase 里边，所以排序的规则变成了先排完所有同一huase的牌，再排序所有shuzi的牌。 调换一下嵌套循环就可以了。

for (String ste : shuzi) {
            for (String str : huase) {
                String poke = ste + str;
                pokers.put(num, poke);
                list.add(num);
                num++;
            }

        }

是斗地主发牌吗？面向对象，写个Poke类表示扑克，这样实现起来比较简单，如下：

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.TreeSet;

public class Test {

    public static class Poke implements Comparable<Poke> {
        public static int sIndex;
        public Integer index;
        public String color;
        public Poke(String color) {
            this.color = color;
            this.index = sIndex++;
        }
        @Override
        public String toString() { return color; }
        @Override
        public int compareTo(Poke o) { return index.compareTo(o.index); }
    }

    public static void main(String[] args) {
        var pokes = new ArrayList<Poke>();
        pokes.add(new Poke("大王"));
        pokes.add(new Poke("小王"));
        var colors = Arrays.asList("黑桃","红桃","梅花","方片");
        var numbers = Arrays.asList("2","A","K","Q","J","10","9","8","7","6","5","4","3");
        numbers.forEach(number -> colors.forEach(color -> pokes.add(new Poke(color + number))));
        Collections.shuffle(pokes); // 洗牌
        var xm = new TreeSet<Poke>();
        var xh = new TreeSet<Poke>();
        var xq = new TreeSet<Poke>();
        while (!pokes.isEmpty()) {
            xm.add(pokes.remove(0)); // 发牌
            xh.add(pokes.remove(0)); // 发牌
            xq.add(pokes.remove(0)); // 发牌
        }
        System.out.println("小明：" + xm);
        System.out.println("小红：" + xh);
        System.out.println("小强：" + xq);
    }

}

运行效果如下：

小明：[黑桃2, 梅花2, 方片2, 红桃A, 梅花A, 方片A, 红桃K, 方片K, 黑桃Q, 梅花Q, 梅花J, 黑桃10, 红桃10, 梅花10, 黑桃9, 梅花8, 方片6, 梅花4]
小红：[黑桃A, 红桃J, 方片J, 方片10, 红桃9, 方片8, 黑桃7, 梅花7, 方片7, 红桃6, 梅花6, 黑桃5, 梅花5, 方片4, 黑桃3, 红桃3, 梅花3, 方片3]
小强：[大王, 小王, 红桃2, 黑桃K, 梅花K, 红桃Q, 方片Q, 黑桃J, 梅花9, 方片9, 黑桃8, 红桃8, 红桃7, 黑桃6, 红桃5, 方片5, 黑桃4, 红桃4]
