用随机数填充ArrayList，然后打印数组

import java.util.ArrayList;
import java.util.Random;

ArrayList<Integer> arrayList = new ArrayList<>();

Random random = new Random();

for (int i = 0; i < 数组长度; i++) {
    int randomNumber = random.nextInt(范围);
    arrayList.add(randomNumber);
}

System.out.println(arrayList);

import java.util.ArrayList;
import java.util.Random;

public class RandomArrayList {
    public static void main(String[] args) {
        ArrayList<Integer> arrayList = new ArrayList<>();
        Random random = new Random();

        int 数组长度 = 10;
        int 范围 = 100;

        for (int i = 0; i < 数组长度; i++) {
            int randomNumber = random.nextInt(范围);
            arrayList.add(randomNumber);
        }

        System.out.println(arrayList);
    }
}
