Q1: java语言编程扑克牌
一Java扑克牌代码：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1Java扑克牌代码，展示剩余牌输入其Java扑克牌代码他字符Java扑克牌代码：");
String c=cin.nextLine();
if("1".equals(c)){
int index = (int) (Math.random()*poker.getSize());
poker.remove(index);
}else{
poker.ShowPages();
}
}
/*for(int i = 0;i54;i++){
int index = (int) (Math.random()*poker.getSize());
poker.remove(index);
poker.ShowPages();
}
*/
}
}二Java扑克牌代码：//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 = 0;ihaoma.length;i++){
for(int j = 0;jhuase.length;j++){
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();
}
}
Q2: java写一个扑克牌程序
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]);
} */
}
}
