1.定义扑克的对象 有两个参数a。花色，b数字Poke{ int number, String color, Poker(String color,int number) { this.color=color; this.number=number; }} 2.每一张牌都实例化一个扑克对象。 poke1= new Poke("红桃","10");poke2=new Poke("黑桃","9"); 3.定义游戏规则类，类里定义一个方法，用来比较大小。public comparePoke(Poke poke1,Poke poke2){ if(花色比较){ return 结果； } if(数字比较){ return 结果； }}。调用方法就能比较

····上面有5个类。Came类就是用来游戏的。它会打印游戏结果。
题目所要求的都解决了，不过有一点，那就是排序时又大到小排的。
这个在写代码的时候没有注意到。
代码只会打印游戏的结果，如果你想打印其他的可以在代码中添加。也可以去掉一些注释查看中间过程
使用JAVA编写以下程序：
1、请定义一个名为Card的扑克牌类，该类有两个private访问权限的字符串变量face和suit；分别描述一张牌的牌面值（如：A、K、Q、J、10、9、……3、2等）和花色（如：“黑桃”、“红桃”、“梅花”、“方块”）；定义Card类中的public访问权限的构造方法，为类中的变量赋值；定义protected访问权限的方法getFace()，得到扑克牌的牌面值；定义protected访问权限的方法getSuit()，得到扑克牌的花色；定义方法toString()，返回表示扑克牌的花色和牌面值字符串（如“红桃A”、“梅花10”等）。
2、若应用程序的main方法中，定义字符串数组f和s；分别表示扑克牌的牌面值和花色；定义52个元素的Card类型数组deck，用来存放4个花色的52张牌。如下所示。
String f[] = {"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
String s[] = {"黑桃","红桃","梅花","方块"};
Card deck = new Card[52]；
（1）使用Card类的构造方法给deck数组的52张牌赋值，要求数组中先存放黑桃花色的A、2、3、……、K；然后是红桃花色的A、2、3、……、K；梅花花色的A、2、3、……、K；方块花色的A、2、3、……、K。请写出实现上述功能的程序段。
（2）请编写模拟洗牌的完整程序，即把数组deck中的扑克牌随机打乱存放顺序。
原题如下：
引用内容
private String face; // A, K, Q, J, 10, ... 2
private String suit; // Spade, Heart, Club, Diamond
public Card(String suit, String face) {
this.face = face;
this.suit = suit;
}
protected String getFace() {
return face;
}
protected String getSuit() {
return suit;
}
public String toString() {
return suit + " " + face;
}
解题，完成程序解：

public class Card {
private String face; // A, K, Q, J, 10, ... 2

public Card(String suit, String face) {

this.suit = suit;
}
protected String getFace() {

}
protected String getSuit() {

public String toString() {
return suit + " " + face;
