玩家类

package com.cuihongming;

import java.util.ArrayList;
import java.util.NoSuchElementException;
import java.util.Scanner;

public class Player {
    private int id;
    private String name;

    private static int PlayersNum = 0;
    private static  ArrayList<Integer> IDs = new ArrayList<Integer>();

    public Player() {
        super();
        pokers = new ArrayList<Poker>();

    }

    }

        this.name = name;
    }
    public void addPoker(Poker poker) {
        pokers.add(poker); 
    }

    @SuppressWarnings("resource")
    public static Player makePlayer() {
        Player player = new Player();
        System.out.println("请输入第"+Player.getPlayersNum()+"位玩家的ID和姓名：");
        Scanner in = new Scanner(System.in);

        while(true) {
            System.out.println("请输入ID:");
            try {
                player.setId(in.nextInt());
            }catch(NoSuchElementException e) {
                System.out.println("请输入整数类型的ID!");
                in.next();
                continue;
            }catch(ErrorInputException e) {
                System.out.println("该ID被占用请重新输入！");
                continue;
            }
            break;

        PlayersNum = playersNum;
    }
    public Poker theMaxPoker() {
        Poker biggest = pokers.get(0);
        for(Poker p:pokers) {
            if(biggest.compareTo(p) == -1) {
                biggest = p;

    }
    public void PokersPrint() {
        String str = getName()+":[";
        for(int i = 0;i < pokers.size();i++) {
            if(i == 0) {

        System.out.println(str);
    }
    public static void addID(int id) throws ErrorInputException{
        if(IDs.contains(id)) {
            throw new ErrorInputException("玩家ID被占用");
        }
        IDs.add(id);
    }
}

扩展的数组列表工具类
构造时可用数组初始化

package com.cuihongming;

import java.util.ArrayList;

public class MyArrayList<E> extends ArrayList<E> {

    private static final long serialVersionUID = 125204210876761836L;

    public MyArrayList(E[] e1){
        super();
        for(E e : e1) {
            this.add(e);
        }
    }
}

自定义的错误||非法输入异常类

package com.cuihongming;

import java.util.ArrayList;

public class MyArrayList<E> extends ArrayList<E> {
    /**
     * 
     */
    private static final long serialVersionUID = 125204210876761836L;

    public MyArrayList(E[] e1){
        super();
        for(E e:e1) {
            this.add(e);
        }
    }
}

游戏类

import java.util.ArrayList;

public class Game {
    public static void main(String[] args) {

        System.out.println("----------创建扑克牌----------");

        Player player2 = Player.makePlayer();

        System.out.println("----------欢迎玩家："+player1.getName());
        System.out.println("----------欢迎玩家："+player2.getName());

        System.out.println("玩家各自的手牌为：");
        player1.PokersPrint();
        player2.PokersPrint();
    }
