用Java编写一个随机选择历史美女的代码案例，要求美女数量20个，美女名字不能重复，

代码如下：

import java.util.Random;

public class RandomBeautySelector {
    public static void main(String[] args) {
        String[] beauties = {"西施", "貂蝉", "王昭君", "杨贵妃", "赵飞燕", "花木兰", "祝英台", "慕容芳", "陆小凤", "叶开", "程婴", "苏蓉蓉", "阿珂", "凤九", "韩菱纱", "紫萱", "韩小野", "玉莲", "花无缺", "小龙女"};
        Random random = new Random();
        String[] selectedBeauties = new String[5]; // 随机选择5个美女
        int count = 0;
        while (count < 5) {
            String beauty = beauties[random.nextInt(beauties.length)];
            if (!contains(selectedBeauties, beauty)) { // 确保美女名字不重复
                selectedBeauties[count++] = beauty;
            }
        }
        System.out.println("随机选择的历史美女是：");
        for (String beauty : selectedBeauties) {
            System.out.println(beauty);
        }
    }
    
    private static boolean contains(String[] arr, String str) {
        for (String s : arr) {
            if (str.equals(s)) {
                return true;
            }
        }
        return false;
    }
}

该程序运行时，将从20位历史美女中随机选择5位，输出结果如下：

随机选择的历史美女是：
叶开
祝英台
紫萱
程婴
苏蓉蓉
