java怎么取随机不同的数组

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

public class RandomArray {

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

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

        // 输出随机数组
        System.out.println(Arrays.toString(numbers));
    }
}

import java.util.Random;

public class RandomArray {

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

        // 创建 Random 对象
        Random random = new Random();

        // 创建新数组
        int[] randomNumbers = new int[numbers.length];

        // 将元素从原始数组复制到新数组
        for (int i = 0; i < numbers.length; i++) {
            randomNumbers[i] = numbers[i];
        }

        // 从新数组中随机删除元素
        for (int i = 0; i < randomNumbers.length; i++) {
            int randomIndex = random.nextInt(randomNumbers.length - i);
            int temp = randomNumbers[randomIndex];
            randomNumbers[randomIndex] = randomNumbers[randomNumbers.length - 1 - i];
            randomNumbers[randomNumbers.length - 1 - i] = temp;
        }

        // 输出随机数组
        System.out.println(Arrays.toString(randomNumbers));
    }
}
