创建数组、集合，存放数据
public class FightAgainstLandlords {
/**
* poker集合，存储54张牌
*/
private ArrayList<String> poker;
/**
* colors数组存储牌的花色
*/
private String[] colors;
/**
* numbers数组存储牌的值
*/
private String[] numbers;
}构造方法FightAgainstLandlords
public class FightAgainstLandlords {
public FightAgainstLandlords(ArrayList<String> poker, String[] colors, String[] numbers) {
this.poker = poker;
this.colors = colors;
this.numbers = numbers;
}
}定义打乱牌牌序方法
public class FightAgainstLandlords {
/**
* 存储54张牌
*/
public ArrayList<String> fiftyFive() {
for (String color: colors) {
for (String number: numbers) {
poker.add(color + number);
}
}
poker.add("大王");
poker.add("小王");
// 洗牌，调用Collections类的静态方法shuffle()，用默认随机源对指定列表进行置换
Collections.shuffle(poker);
return poker;
}
}发牌
public class FightAgainstLandlords {
/**
* 发牌
* 获取玩家牌或者底牌
* j = 1, 2, 3 代表玩家牌
* j = 其他数字 代表底牌
*/
public ArrayList<String> licensing(int j, ArrayList<String> pokers) {
// 三个玩家
ArrayList<String> people1 = new ArrayList<>();
ArrayList<String> people2 = new ArrayList<>();
ArrayList<String> people3 = new ArrayList<>();
// 底牌
ArrayList<String> basePoker = new ArrayList<>();
for (int i = 0; i < pokers.size(); i++) {
String p = pokers.get(i);
if ( i < 51) {
if (i % 3 == 0) {
people1.add(p);
} else if (i % 3 == 1) {
people2.add(p);
} else {
people3.add(p);
}
} else {
basePoker.add(p);
}
}
// 返回玩家的牌、底牌
if (j == 1) {
return people1;
} else if (j == 2) {
return people2;
} else if (j == 3) {
return people3;
} else {

}
}
}测试FightAgainstLandlords类
import java.util.ArrayList;
public class DemoFightAgainstLandlords {
public static void main(String[] args) {
ArrayList<String> poker = new ArrayList<>();
String[] colors = {"红桃", "黑桃", "梅花", "方块"};
String[] numbers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};
// new一个斗地主
FightAgainstLandlords fightAgainstLandlords = new FightAgainstLandlords(poker, colors, numbers);
// 54张牌
ArrayList<String> pokers = fightAgainstLandlords.fiftyFive();
// 获取每个人的牌，和底牌
ArrayList<String> people1 = fightAgainstLandlords.licensing(1, pokers);
ArrayList<String> people2 = fightAgainstLandlords.licensing(2, pokers);
ArrayList<String> people3 = fightAgainstLandlords.licensing(3, pokers);
ArrayList<String> basePoker = fightAgainstLandlords.licensing(4, pokers);
// 看一下它们每个人的牌，和底牌
System.out.println("people1：" + people1);
System.out.println("people2：" + people2);
System.out.println("people3：" + people3);
System.out.println("basePoker：" + basePoker);
}
}输出结果（每个人的牌，和底牌都是随机的）：
people1：[红桃3, 梅花J, 梅花K, 方块J, 方块K, 梅花10, 红桃6, 梅花9, 黑桃Q, 红桃Q, 梅花4, 黑桃A, 方块2, 红桃8, 方块4, 黑桃8, 红桃K]
people2：[梅花A, 方块3, 小王, 黑桃J, 红桃7, 方块5, 方块9, 黑桃10, 方块8, 梅花Q, 方块6, 梅花6, 红桃10, 方块Q, 黑桃5, 黑桃2, 红桃A]
people3：[梅花5, 梅花8, 黑桃7, 黑桃4, 红桃9, 黑桃9, 黑桃K, 方块7, 黑桃6, 梅花3, 方块10, 红桃4, 黑桃3, 红桃5, 大王, 红桃J, 方块A]
basePoker：[红桃2, 梅花2, 梅花7]
