纸牌游戏的设计与问题，目前还没有完成有几点疑惑

我目前学习遇到的问题是，用如下代码写出的程序，最后输出的结果是Hashcoad(),为什么呢？我是新手不太理解，哪位可以帮我解答一下，附图，我的运行问题

扑克类

package com.ljb.study01;

public class PuKe {

    public String hs;
    public String sz;
    //定义一个扑克集（花色，数字）
    PuKe(String sz,String hs) {
        this.hs=hs;
        this.sz=sz;
    } 
    public PuKe() {
    }
}

玩家类

package com.ljb.study01;

import java.util.List;

public class People {
    public int id;
    public String name;
    public PuKe puk;
    public People(int id , String name,PuKe puk) {
        this.id=id;
        this.name=name;
        this.puk=puk;
    }
}

功能类
