如何创建一个生成随机数的arraylist的方法

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

public static void main(String[] args) {
    ArrayList<Integer> random = new ArrayList<Integer>();
    random = getRandom(100, 100);
    for (int i = 0; i < random.size(); i++)
        System.out.println(random.get(i));
}

private static ArrayList<Integer> getRandom(int range, int size) {
    ArrayList<Integer> randomNumbers = new ArrayList<Integer>();
    for (int i = 0; i < size; i++)
        randomNumbers.set(i, new Random().nextInt(range)+1);
    return randomNumbers;
}
