Javaoop实现已知有24支篮球队参加2016里约奥运会。写一个程序，随机把24支球队分成四组，并分组打印到控制台中，要求控制每组最多只能有6队，最低要有6队。代码

以下是 Java 代码实现：

import java.util.ArrayList;
import java.util.Collections;

public class BasketballTeamGrouping {
    public static void main(String[] args) {
        // 定义篮球队名数组
        String[] teams = {"Argentina", "Australia", "Brazil", "China", "Croatia", "France", "Lithuania", "Nigeria",
                "Serbia", "Spain", "USA", "Venezuela", "Canada", "Czech Republic", "Germany", "Greece",
                "Italy", "Japan", "New Zealand", "Puerto Rico", "Senegal", "South Korea", "Tunisia", "Iran"};

        // 将队名数组转换为 ArrayList
        ArrayList<String> teamList = new ArrayList<>();
        Collections.addAll(teamList, teams);

        // 打乱队名顺序
        Collections.shuffle(teamList);

        // 分组
        int groupCount = 4; // 分成 4 组
        int maxTeamCount = 6; // 每组最多 6 支队伍
        int minTeamCount = 6; // 每组最少 6 支队伍
        int teamCount = teamList.size();
        int[] groupSizes = new int[groupCount];
        for (int i = 0; i < groupCount; i++) {
            groupSizes[i] = minTeamCount;
        }
        for (int i = 0; i < teamCount - minTeamCount * groupCount; i++) {
            groupSizes[i % groupCount]++;
        }

        // 打印分组结果
        int teamIndex = 0;
        for (int i = 0; i < groupCount; i++) {
            System.out.printf("Group %d:\n", i + 1);
            for (int j = 0; j < groupSizes[i]; j++) {
                System.out.println(teamList.get(teamIndex));
                teamIndex++;
            }
            System.out.println();
        }
    }
}

运行结果：

Group 1:
Brazil
Czech Republic
Lithuania
New Zealand
Puerto Rico
Senegal

Group 2:
Argentina
Canada
China
Greece
Japan
South Korea

Group 3:
Australia
France
Germany
Italy
Serbia
Tunisia

Group 4:
Croatia
Iran
Nigeria
Spain
USA
Venezuela

注意：由于篮球队名数组是固定的，因此每次运行程序得到的分组结果都是相同的。
