请问用java数组编写洗牌程序怎么写？我刚学java，请多指教，谢谢！！！
package xly04;
import java.util.Random;
public class ArrayDemo3 {
/**
* 数组应用：
* 1 随机洗牌
* 2 顺序发牌
*/
public static void main(String[] args) {
String[] cards=new String[]{"黑桃A","黑桃2","黑桃3","黑桃4",
"黑桃5","黑桃6","黑桃7","黑桃8","黑桃9","黑桃10","黑桃J","黑桃Q","黑桃K",
"红桃A","红桃2","红桃3","红桃4","红桃5","红桃6","红桃7","红桃8","红桃9",
"红桃10","红桃J","红桃Q","红桃K","方块A","方块2","方块3","方块4","方块5",
"方块6","方块7","方块8","方块9","方块10","方块J","方块Q","方块K","梅花A",
"梅花2","梅花3","梅花4","梅花5","梅花6","梅花7","梅花8","梅花9","梅花10",
"梅花J","梅花Q","梅花K","大王","小王"};
//Random random=new Random();.......(1)
//int index=random.nextInt(10);//[0,10) %10
//System.out.println(index);
//String card=cards[random.nextInt(cards.length)];//长度为8，随机下标[0,8)
//System.out.println(card);//随机的某张牌
for(int i=cards.length-1;i=1;i--){
int j=new Random().nextInt(i);//或者（1）不注销用int j=random.nextInt(i);
String t=cards[i];
cards[i]=cards[j];
cards[j]=t;
}
for(int i=0;icards.length;i++){
System.out.print(cards[i]+",");
}
System.out.println();//输出回车字符
//顺序发牌：顺序的将每个牌发给每个人
String[] players=new String[]{"马伊琍","文章","六六"};
//int i=0;
//System.out.println(players[i++%players.length]);
//System.out.println(players[i++%players.length]);
//System.out.println(players[i++%players.length]);
//System.out.println(players[i++%players.length]);
//System.out.println(players[i++%players.length]);
//System.out.println(players[i++%players.length]);
for(int i=0;icards.length;i++){
//i=0,1,2,3,4,5,6,7
String card=cards[i];//card 代表每张扑克牌
String player=players[i%players.length];
//player代表每个玩游戏的人
System.out.println(player+":"+card);
}
}
}
用java ArrayList集合编写扑克牌洗牌与发牌
import java.util.ArrayList;
import java.util.Random;
public class PokerDemo {
ArrayListCard poker = new ArrayListCard();
Player[] players;
int n = 4;
String[] name = {"Wang", "Zhang", "Li", "Yuan"};
public PokerDemo() {
players = new Player[n];
for(int i = 0; i players.length; i++)
players[i] = new Player(name[i]);
for(int i = 0; i 4; i++)
for(int j = 0; j 13; j++)
poker.add(new Card(i, j));
System.out.println("洗牌前: " + poker);
xipai();
System.out.println("洗牌后: " + poker);
fapai();
System.out.println("发牌后: ");
for(int i = 0; i players.length; i++)
System.out.println(players[i]);
}
public void xipai() {
Random r = new Random();
ArrayListCard tmp = new ArrayListCard();
while(!poker.isEmpty()) {
int index = r.nextInt(poker.size());
Card card = poker.get(index);
tmp.add(card);
poker.remove(index);
}
poker = new ArrayListCard(tmp);
}
public void fapai() {
int p = 0;
while(!poker.isEmpty()) {
Card card = poker.get(0);
players[p].add(card);
p = (p + 1) % n;
poker.remove(0);
}
}
public static void main(String[] args) {
new PokerDemo();
}
}
class Card {
int val, sty;
final String[] value = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};
final String[] style = {"黑桃", "红心", "梅花", "方块"};
public Card(int s, int v) {
sty = s;
val = v;
}
public String toString() {
return style[sty]+ " " + value[val];
}
}
class Player {
ArrayListCard cards = new ArrayListCard();
String name;
public Player(String n) {
name = n;
}
public void add(Card card) {
cards.add(card);
}
public String toString() {
return name + ":\t" + cards;
}
}
