做完了作业，但是感觉异常处理和MAP类还是不熟，程序里没怎么用到。

Game.java主程序：

package SimplePoker;
import java.util.InputMismatchException;
import java.util.Scanner;
public class Game {
static int ID1,ID2;
static String name1,name2;
public static void main(String[] args) {

Pokercards poker = new Pokercards();
game.createplayer();
Player player1 = new Player(ID1,name1);
Player player2 = new Player(ID2,name2);
poker.disorder();
game.deal(poker, player1, player2);
System.out.println("----------开始游戏...----------");
int flag = player1.compareTo(player2);
if(flag==1)System.out.println("----------玩家："+player1.name+"获胜！----------");
else System.out.println("----------玩家："+player2.name+"获胜！----------");
System.out.println("玩家各自的手牌为：");
System.out.println(player1.name+":["+player1.cards[0]+","+player1.cards[1]+"]");
System.out.println(player2.name+":["+player2.cards[0]+","+player2.cards[1]+"]");
}
//发牌

System.out.println("----------发牌结束！----------");
}
public void createplayer() {

System.out.println("----------创建玩家...----------");
System.out.println("请输入第1位玩家的ID和姓名:");
