java语言编程扑克牌

一：import java.util.Scanner

public class Play {

/**

* 玩牌

*/

public static void main(String[] args) {

Poker poker = new Poker()

boolean over = false

Scanner cin=new Scanner(System.in)

while(!over){

System.out.println("打牌输入1，展示剩余牌输入其他字符：")

String c=cin.nextLine()

if("1".equals(c)){

int index = (int) (Math.random()*poker.getSize())

poker.remove(index)

}else{

poker.ShowPages()

}

}

/*for(int i = 0i<54i++){

int index = (int) (Math.random()*poker.getSize())

poker.remove(index)

poker.ShowPages()

}

*/

}

}二：//牌

public class Page { private String huase = ""

private String haoma = ""

public Page(String huase,String haoma){

this.huase = huase

this.haoma = haoma

}

public String show(){

return this.huase+this.haoma

}

}三：import java.util.ArrayList

import java.util.Iterator

import java.util.List

/**

* 一副扑克

*/

public class Poker {

private List pages = new ArrayList()

public Poker(){

String huase[] = new String[]{"黑桃","红桃","草花","方块"}

String haoma[] = new String[]{"A","2","3","4","5","6","7","8","9","10"

,"J","Q","K"}

for(int i = 0i<haoma.lengthi++){

for(int j = 0j<huase.lengthj++){

pages.add(new Page(huase[j],haoma[i]))

}

}

pages.add(new Page("","大王"))

pages.add(new Page("","小王"))

}

public void ShowPages(){

System.out.println("展示剩余牌：")

for(Iterator i = pages.iterator()i.hasNext()){

System.out.println(((Page)i.next()).show())

}

}

//打牌

public void remove(int index){

pages.remove(index)

}

//剩余牌数

public int getSize(){

return pages.size()

}

}

修改的部分我加了#########你看一下吧

//这个初始化方法

publicvoidinitcard()

{

String num[]={"A","2","3","4","5","6","7","8","9","10","J","Q","K"}

String suit[]={"方块","梅花","红桃","黑桃"}

String bigwang,xiaowang

card = newCardClass[54]//#######初始化54张而不是52张

for(inti=0i<52i++)

{

card[i] = newCardClass(num[i%13],suit[i/13])

}

car[52] = new CardClass("大王","")//#####初始化大王

car[53] = new CardClass("小王","")//######初始化小王

}

publicvoidshufflecard()//洗牌

{

Random rd = newRandom()

for(inti=0i<54i++) //##########由52变为54

{

int j = rd.nextInt(54)//生成随机数 #######52变54

CardClass temp = card[i]//交换

card[i]=card[j]

card[j]=temp

}

}

publicvoiddealcard()//发牌

{

for(inti=0i<54i++)//##########由52变成54

{

if(i%12==0) System.out.println("\n")

System.out.print(card[i])

}

}

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 = 0i <sizei++) {

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 = 0i <s.lengthi++) {

for (int j = 0j <f.lengthj++) {

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 = 0i <numOfShufflei++) {

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=0i<deck.lengthi++)

{

System.out.println(deck[i])

} */

}

}
