Java四人扑克发牌，请教高手将代码进行更好的缩进，在简洁点，最主要性能。
扑克牌还是自己写个对象比较好吧 属性就是花色跟牌值
至于发牌什么java扑克洗牌发牌代码的 还是用集合来吧 数组操作起来比较麻烦
代码实在是懒得写java扑克洗牌发牌代码了 就提点建议
用集合java扑克洗牌发牌代码的好处比如说洗牌直接就可以用 collectionsjava扑克洗牌发牌代码的静态方法 还有就是 回复初始状态排序 也可以也可以自定义比较器来比较

Q2: 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);
}
}
}
Q3: java 中如何实现一副扑克牌洗牌的功能。如果无法书写完整的代码，可以用文字描述出自己的实现思路
1.定义牌类
public class Card{
public int id;//牌大小
public String number;//牌值名称
public String color;//花色
}
2.定义牌组,用ArrayList存放所有牌
ArrayListCard cardGroup =new ArrayListCard();
3.定义花色枚举
public static final String[] COLORS=new String[]{"方块","梅花","红桃","黑桃"};
4.定义牌值大小枚举
public static fina String[] CARDVALUES=new String[]{"A","1","2","3",
"4","5","6","7","8","9","10","J","Q","K","King_Small","King_Big"};
5.初始化牌组,这就是一副新牌，没切过，己经排好序的
public void initCardGroup(){
//加入A~K
for(int i=0;i13;i++){
for (int j=0;j4;j++){
//生成一张牌的对象
Card card=new Card();
card.id=i;
card.color=COLORS[j];
card.munber=CARDVALUES[i];
//将对象加入牌组
cardGroup.add(card);
}
}
//加入大小王
Card card_k1=new Card();
card_k1.id=13;
card_k1.color="King_Small";
card_k1.number="King_Small";
cardGroup.add(card_k1);
Card card_k2=new Card();
card_k2.id=14;
card_k2.color="King_big";
card_k2.number="King_big";
cardGroup.add(card_k2);
}
6. 洗牌，将原牌组打乱，得到新的牌组
public ArrayListCard flushCardsGroup(ArrayListCard src){
ArrayListCard result=new ArrayListCard();
while(src.size0){
int size=src.size();
//以size为限，生成0~size之间的随机数
Random r=new Random();
int index=r.nextInt(size);
//对index做个检查
if(index0){index=0;}
if(indexsize-1){index=size-1;}
//index就是捡出来的牌，加到新的数组中，从原来数组中删除
Card card=src.get(index);
result.add(card);
card.remove(index);
}
return result;
}
Q4: 用JAVA写个代码，实现52张牌随机分给四个人
java内的Collections类自带了一个shuffle洗牌算法。
static void shuffle(List? list)
使用默认随机源对指定列表进行置换。
static void shuffle(List? list, Random rnd)
使用指定的随机源对指定列表进行置换。
现在你可以把52张牌放进一个List里，调用他的shuffle算法打乱顺序。
