Java脚本。如何选择数组中的任意几项

import java.util.Random;

public class Main {
    public static void main(String[] args) {
        String[] array = {"item1", "item2", "item3", "item4", "item5"};
        int numItemsToSelect = 3; // 选择的元素数量

        Random random = new Random();
        for (int i = 0; i < numItemsToSelect; i++) {
            int randomIndex = random.nextInt(array.length);
            String selectedItem = array[randomIndex];
            System.out.println(selectedItem);
        }
    }
}

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

public class Main {
    public static void main(String[] args) {
        String[] array = {"item1", "item2", "item3", "item4", "item5"};
        int numItemsToSelect = 3; // 选择的元素数量

        List<String> list = Arrays.asList(array);
        Collections.shuffle(list);

        for (int i = 0; i < numItemsToSelect; i++) {
            String selectedItem = list.get(i);
            System.out.println(selectedItem);
        }
    }
}
