java入门三—扑克牌简易游戏

 - Player类

import java.awt.List;
import java.util.LinkedList;

public class Player {
    int id;
    String name;
    LinkedList<Object> handcard = new LinkedList<>();

    public Player(int id,String name) {
        this.id=id;
        this.name=name;
        //System.out.println("欢迎"+name);
    }
}

 - 自定义异常类

import javax.management.RuntimeOperationsException;

public class Playerex extends RuntimeException {

public Playerex(RuntimeException a, String b) {
    super(b);
}

public Playerex(String me) {
    super(me);
}
// private static final long serialVersionUID = 1L;

}

 - PukerCards类

 - 测试类

import java.util.Scanner;

public class Text {
