Java模拟发牌、洗牌
1).写一个卡片类Card类, 含两个属性: 一个花色(Suit)，一个是点数(Rank).
2).写个扑克牌Poker类，含52张 Card，要用集合来存放
2张副牌（大王和小王）不计算
3).写一个发牌者 Dealer 类,有属性 扑克牌Poker类，并提供方法：
发牌 deal(), 洗牌 shuffle()
4).写一个 玩家 Player 类
5).在单元测试中，可以初始化3个玩家，并由发牌者轮流发牌。
最后打印3个玩家手中的牌、
Card类：
public class Card {
public String suit;
public int rank;
public String getSuit() {
return suit;
}

} Dealer类（发牌者）
public class Dealer {
public static ArrayList arrayList = new ArrayList<>();
/**
* 创建扑克牌
*/
public ArrayList deal(String[] suit,int[] rank){
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 13; j++) {
arrayList.add(new Card(suit[i], rank[j]));
}
}
return arrayList;
}
/**
* 洗牌
*/
public void shuffle(ArrayList arrayList) {
Collections.shuffle(arrayList);
}
} 测试类：
public class Test {
public static void main(String[] args) {
ArrayList nowCardList = new ArrayList<>();
//创建玩家
Player[] p = new Player[3];
p[0] = new Player(1, "jim");
p[1] = new Player(2, "tom");
p[2] = new Player(3, "lucy");
Dealer dealer = new Dealer();
//创建扑克
String[] suit = {"黑桃","红心","方片","梅花"};
int[] rank = {1,2,3,4,5,6,7,8,9,10,11,12,13};
ArrayList arrayList = dealer.deal(suit,rank);
dealer.shuffle(arrayList);
//发牌
for(int i=0; i<52; i++){
if(i%3 == 0){
p[0].getCard(arrayList.get(i));
}else if(i%3 == 1){
p[1].getCard(arrayList.get(i));
}else if(i%3 == 2){
p[2].getCard(arrayList.get(i));
}
}
for(int i = 0;i < 3;i++) {
System.out.println("第"+(i+1)+"个人拿到的牌是"+p[i].getList());
}
}
