在這類playingCcards下創建player一點問題沒有

package?com_poker_game;

import?java.util.*;

public?class?playingCcards?{
	player?player=new?player();//==============在這沒問題========================
	List<Cards>??cardsList=new?ArrayList<Cards>();
	List<player>?playerList=new?ArrayList<player>();
	String[]?huaSe={"黑桃","方片","草花","紅桃"};
	String[]?daXiao={"2","3","4","5","6","7","8","9",
			?"10","J","Q","K","A"};
	

但是放在playingCcards 類中的方法sendPokers和compare中，運行就會提示報錯

(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。這是怎么回事呢？？
