java 数组怎么乱序

import java.util.Arrays;
import java.util.Collections;

public class ArrayShuffle {

    public static void main(String[] args) {
        int[] numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

        // 打乱数组的顺序
        Collections.shuffle(Arrays.asList(numbers));

        // 输出打乱后的数组
        System.out.println(Arrays.toString(numbers));
    }
}

import java.util.Random;

public class ArrayShuffle2 {

    public static void main(String[] args) {
        int[] numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

        // 创建一个随机数生成器
        Random rand = new Random();

        // 遍历数组
        for (int i = 0; i < numbers.length; i++) {
            // 随机选择另一个数组元素
            int j = rand.nextInt(numbers.length);

            // 交换两个元素的值
            int temp = numbers[i];
            numbers[i] = numbers[j];
            numbers[j] = temp;
        }

        // 输出打乱后的数组
        System.out.println(Arrays.toString(numbers));
    }
}
