java int数组转ArrayList＜Integer＞

Posted 2021-12-13 zhangjin1120

JDK中的方法

int[] tickets = new int[]{84,49,5,24,70,77,87,8};
ArrayList<Integer> list = (ArrayList<Integer>)Arrays.stream(tickets).boxed().collect(Collectors.toList());

循环插入

		int[] tickets = new int[]{84,49,5,24,70,77,87,8};
        ArrayList<Integer> intList = new ArrayList<>();
        for (int i = 0; i < tickets.length; i++) {
            intList.add(Integer.valueOf(tickets[i]));
        }

很遗憾，没有别的更简单的方法了。
