1. 牌面的创建

可以先创建一个类来表示牌面的花色和面值

public class MyCard {//扑克牌牌面数值public int value;//扑克牌花色public String design;@Overridepublic String toString() {return "[ "+design+" "+value+" ]";}
}

2. 牌面的设计

牌面创建好了之后，需要进行许多加工

2.1 创建一副牌

/*
* 创建一副牌
* */
public List<MyCard> createCard() {List<MyCard> list = new ArrayList<>(51);for (int i = 1; i <= 13; i++) {for (int j = 0; j < SUIT.length; j++) {MyCard myCard = new MyCard();myCard.design = SUIT[j];myCard.value = i;list.add(myCard);}}return list;
}

2.2 洗牌

/*
* 洗牌
* */
public void shuffleCard(List<MyCard> list) {Random random = new Random();for (int i = list.size() - 1; i >= 0; i--) {int ranCount = random.nextInt(52);swap(list,i,ranCount);}
}/*
* 交换
* */
private void swap(List<MyCard> list,int i,int ranCount) {MyCard ret = list.get(i);list.set(i,list.get(ranCount));list.set(ranCount,ret);
}

2.3 发牌

/*
* 现有 5 个人，每人抽 6 张牌比大小
* */
List<List<MyCard>> peoples = new ArrayList<>();
peoples.add(new ArrayList<>());
peoples.add(new ArrayList<>());
peoples.add(new ArrayList<>());
peoples.add(new ArrayList<>());
peoples.add(new ArrayList<>());
peoples.add(new ArrayList<>());for (int i = 0; i < 5; i++) {  // 5人for (int j = 0; j < 6; j++) {  //抽 6 张牌peoples.get(i).add(list.remove(0));}
}System.out.println("第一个人的牌：");
System.out.println(peoples.get(0));
System.out.println("第二个人的牌：");
System.out.println(peoples.get(1));
System.out.println("第三个人的牌：");
System.out.println(peoples.get(2));
System.out.println("第四个人的牌：");
System.out.println(peoples.get(3));
System.out.println("第五个人的牌：");
System.out.println(peoples.get(4));

3. 全部码源

3.1 MyCard.java

package deom1;public class MyCard {//扑克牌牌面数值public int value;//扑克牌花色public String design;@Overridepublic String toString() {return "[ "+design+" "+value+" ]";}
}

3.2 MyCardGame.java

package deom1;import java.util.ArrayList;
import java.util.List;
import java.util.Random;public class MyCardGame {/** 定义花色的种类* */public String[] SUIT = {"♥","♣","♦","♠"};/** 创建一副牌* */public List<MyCard> createCard() {List<MyCard> list = new ArrayList<>(51);for (int i = 1; i <= 13; i++) {for (int j = 0; j < SUIT.length; j++) {MyCard myCard = new MyCard();myCard.design = SUIT[j];myCard.value = i;list.add(myCard);}}return list;}/** 洗牌* */public void shuffleCard(List<MyCard> list) {Random random = new Random();for (int i = list.size() - 1; i >= 0; i--) {int ranCount = random.nextInt(52);swap(list,i,ranCount);}}/** 交换* */public void swap(List<MyCard> list,int i,int ranCount) {MyCard ret = list.get(i);list.set(i,list.get(ranCount));list.set(ranCount,ret);}}

3.3 PlayCard.java

package deom1;import java.util.ArrayList;
import java.util.List;public class PlayCard {public static void main(String[] args) {MyCardGame myCardGame = new MyCardGame();System.out.println("新的扑克牌：");List<MyCard> list = myCardGame.createCard();System.out.println(list);System.out.println("洗牌：");myCardGame.shuffleCard(list);System.out.println(list);/** 现有 5 个人，每人抽 6 张牌比大小* */List<List<MyCard>> peoples = new ArrayList<>();peoples.add(new ArrayList<>());peoples.add(new ArrayList<>());peoples.add(new ArrayList<>());peoples.add(new ArrayList<>());peoples.add(new ArrayList<>());peoples.add(new ArrayList<>());for (int i = 0; i < 5; i++) {  // 5人for (int j = 0; j < 6; j++) {  //抽 6 张牌peoples.get(i).add(list.remove(0));}}System.out.println("第一个人的牌：");System.out.println(peoples.get(0));System.out.println("第二个人的牌：");System.out.println(peoples.get(1));System.out.println("第三个人的牌：");System.out.println(peoples.get(2));System.out.println("第四个人的牌：");System.out.println(peoples.get(3));System.out.println("第五个人的牌：");System.out.println(peoples.get(4));}
}
