求大神解答个问题，在写的过程中我遇了这个问题
让我十分不解 ，就是player player=new player();的问题！
在这类playingCcards下创建player一点问题没有package com_poker_
import java.util.*;
public class playingCcards {
player player=new player();//==============在这没问题========================
List&Cards&
cardsList=new ArrayList&Cards&();
List&player& playerList=new ArrayList&player&();
String[] huaSe={"黑桃","方片","草花","红桃"};
String[] daXiao={"2","3","4","5","6","7","8","9",
"10","J","Q","K","A"};
但是放在playingCcards 类中的方法sendPokers和compare中，运行就会提示报错(Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1)，而且compare中的int size=player.playerOneCards.size();System.out.println("lalal"+size);，size死活就是0。这是怎么回事呢？？package com_poker_
import java.util.*;
public class playingCcards {
//player player=new player();=============不放这里了，这没了==============
List&Cards&
cardsList=new ArrayList&Cards&();
List&player& playerList=new ArrayList&player&();
String[] huaSe={"黑桃","方片","草花","红桃"};
String[] daXiao={"2","3","4","5","6","7","8","9",
"10","J","Q","K","A"};
// public void createCards(){
for(int i=0;i&huaSe.i++){
for(int j=0;i&daXiao.j++){
cardsList.add(new Cards(huaSe[i],daXiao[j]));
//cardsSet输出所有扑克牌
System.out.print(huaSe[i]+daXiao[j]+" ");
//建立扑克
public void createCards() {
System.out.println("----------------创建扑克牌----------------");
for(int i = 0;i & huaSe.i++){
for(int j = 0;j & daXiao.j++){
cardsList.add(new Cards(huaSe[i],daXiao[j]));
System.out.print(huaSe[i]+daXiao[j]+" ");
System.out.println("\n"+"-------------扑克牌创建成功！--------------");
* 另外一种输出方法 就不用了
for (Cards card : cardsList) {
System.out.print(card.getType() + card.getNum() + ",");
System.out.println("总共有" + cardsList.size() + "张牌。");
//------------------------------洗牌
Collections.shuffle(cardsList);
System.out.println("--------------洗牌完成--------------");
//建立玩家
public void creatPlayer(){
int playerID=0;
String playerN
Scanner sc=new Scanner(System.in);
for(int k=1;k&=2;k++){
System.out.println("请输入第"+k+"位玩家ID：");
//while(true) 想要在catch后面继续写代码 while(true)才好使
while(true){
sc=new Scanner(System.in);
playerID=sc.nextInt();
}catch(Exception e){
System.out.println("必须为整数");
System.out.println("请输入第"+k+"位玩家姓名：");
playerName=sc.next();
playerList.add(new player(playerID,playerName));
//遍历playerlist查看此时系统中有哪些玩家
for(int p=0;p&playerList.size();p++){
System.out.println("目前存在的玩家有："+playerList.get(p).id+
"+playerList.get(p).name);
public void sendPokers(){
player player=new player();//===============放这里=================
for(int u=0;u&4;u++){
//哈哈很喜欢这个方法 u==0+(2*n)，再多人也不怕！！！！！
if(u==0+(2*n)){
player.playerOneCards.add(cardsList.get(u));
if(u==1+(2*n)){
player.playerSecondCards.add(cardsList.get(u));
//n++的位置很重要的啊！！！！！！！！！！！！！！！！
for(int p=0;p&player.playerCards.size();p++){
System.out.println("目前已经发出的牌有："+player.playerCards.get(p));
for(Cards pcr1:player.playerOneCards){
System.out.println("玩家"+playerList.get(0).name+"的牌有："
+pcr1.type+pcr1.num);
for(Cards pcr2:player.playerSecondCards){
System.out.println("玩家"+playerList.get(1).name+"的牌有："
+pcr2.type+pcr2.num);
//比较两人手牌大小
public void compare(){
player player=new player();//===========在这也new一下=================
List&Cards& everyoneMaxPokeList=new ArrayList&Cards&();
Collections.sort(player.playerOneCards);
Collections.sort(player.playerSecondCards);
//pareTo(per1.playerOneCards,per1.playerSecondCards);
//获取手牌list的size
int size=player.playerOneCards.size();
//System.out.println("lalal"+size);
//获得每个人最大的手牌
System.out.println("玩家"+playerList.get(0).name+"的最大牌："+player.playerOneCards.get(size-1).type+
player.playerOneCards.get(size-1).num);
System.out.println("玩家"+playerList.get(1).name+"的最大牌："+player.playerSecondCards.get(size-1).type+
player.playerSecondCards.get(size-1).num);
//把每个人最大手牌放入everyoneMaxPokeList中再做比较
everyoneMaxPokeList.add(player.playerOneCards.get(size-1));
everyoneMaxPokeList.add(player.playerSecondCards.get(size-1));
Collections.sort(everyoneMaxPokeList);
int sze=everyoneMaxPokeList.size();
//看看everyoneMaxPokeList中最大的数据到底属于谁！
//下面这种写法equal方法有问题
if(everyoneMaxPokeList.get(sze-1).equals(player.playerOneCards)){
System.out.println("Winner is:"+playerList.get(0).name);
System.out.println("Winner is:"+playerList.get(1).name);
if(player.playerOneCards.contains(everyoneMaxPokeList.get(sze-1))){
System.out.println("Winner is:"+playerList.get(0).name);
System.out.println("Winner is:"+playerList.get(1).name);
* @param args
public static void main(String[] args) {
// TODO Auto-generated method stub
playingCcards pc=new playingCcards();
pc.createCards();
pc.creatPlayer();
pc.sendPokers();
pc.compare();
