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

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:
程序代码
package poker;
public class Card {
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;
}
public static void shuffle(Card[] deck, int startIndex, int size,
int splitIndex) { //shuffle洗牌
System.out.println("startIndex:" + startIndex);
if (splitIndex * 2 size) { //if rand is 30
Card.swap(deck, startIndex, splitIndex, size - splitIndex); //[52]、0、30、22
shuffle(deck, size - splitIndex, splitIndex, size - splitIndex); //[52]、22、30、22
} else if (splitIndex * 2 size) { //if rnd is 10
Card.swap(deck, startIndex, size - splitIndex, splitIndex); //[52]、0、42、10
shuffle(deck, startIndex, size - splitIndex, splitIndex); //[52]、0、42、10
} else {
Card.swap(deck, startIndex, splitIndex, splitIndex);
}
}
public static void swap(Card[] deck, int srcIndex, int dstIndex, int size) { //交换
//SRC是在本位置显示:source的缩写,源的意思 HREF是点击后连接的目标:HyperlinkReference,超链接引用
String face = "";
String suit = "";
for (int i = 0; i size; i++) {
face = deck[srcIndex + i].face;
suit = deck[srcIndex + i].suit;
deck[srcIndex + i].face = deck[dstIndex + i].face;
deck[srcIndex + i].suit = deck[dstIndex + i].suit;
deck[dstIndex + i].face = face;
deck[dstIndex + i].suit = suit;
}
}
/**
* @param args
*/
public static void main(String[] args) {
//第一问解答
Card[] deck = new Card[52];
String f[] = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J",
"Q", "K"};
String s[] = {"Spade", "Heart", "Club", "Diamond"};
for (int i = 0; i s.length; i++) {
for (int j = 0; j f.length; j++) {
deck[i * 13 + j] = new Card(s[i], f[j]); //依次存入数组之中,每13张一回合
}
}
//第二问解答
int rnd = 0;
int numOfShuffle = 10;
for (int i = 0; i numOfShuffle; i++) {
rnd = (int) Math.abs(Math.random() * 52); //Math.random()返回大于或等于 0.0 但小于 1.0 的伪随机 double 值。
Card.shuffle(deck, 0, deck.length, rnd);
}
// Test
/*
for (int i=0; ideck.length; i++)
{
System.out.println(deck[i]);
} */
}
