简易扑克牌游戏

主要为了练习List，Map的用法，以及异常处理的应用

Poker类

public class Poker implements Comparable<Poker> {
    public String desgin;
    public String num;
    Poker(String desgin,String num){
    	this.desgin=desgin;
    	this.num=num;
    }
	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((desgin == null) ? 0 : desgin.hashCode());
		result = prime * result + ((num == null) ? 0 : num.hashCode());
		return result;
	}
	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (!(obj instanceof Poker))
			return false;
		Poker other = (Poker) obj;
		if (desgin == null) {
			if (other.desgin != null)
				return false;
		} else if (!desgin.equals(other.desgin))
			return false;
		if (num == null) {
			if (other.num != null)
				return false;
		} else if (!num.equals(other.num))
			return false;
		return true;
	}
	@Override
	//比较扑克大小（comparTo其实就是在不断调用equals）
	public int compareTo(Poker o) {
		// TODO Auto-generated method stub
		if(this.num==o.num){
			return this.desgin.compareTo(o.desgin);
		}
		else{
			return this.num.compareTo(o.num);
		}
	}

    
}

Player类

	@Override
	public int hashCode() {

	}
	
}
