String[] arr = {"陈庆静", "杨明", "刘思若", "韩珊珊", "刘博臻", "宁培欣", "苗亚辉", "郭玉洁"}; shuffle(arr);

根据提供的引用内容，你可以使用Fisher-Yates洗牌算法来打乱一个字符串数组。下面是一个示例代码：

import java.util.Random;

public class ShuffleArray {
    public static void shuffle(String[] arr) {
        Random rand = new Random();
        for (int i = arr.length - 1; i > 0; i--) {
            int j = rand.nextInt(i + 1);
            String temp = arr[i];
            arr[i] = arr[j];
            arr[j] = temp;
        }
    }

    public static void main(String[] args) {
        String[] arr = {"陈庆静", "杨明", "刘思若", "韩珊珊", "刘博臻", "宁培欣", "苗亚辉", "郭玉洁"};
        shuffle(arr);
        for (String name : arr) {
            System.out.print(name + " ");
        }
    }
}

这段代码使用了Fisher-Yates洗牌算法来随机打乱了字符串数组`arr`中的元素顺序。你可以将这段代码复制到你的Java开发环境中运行，以查看打乱后的结果。
