Java 数组 转 ArrayList

Long[] arrayLong= new Long[]{1L,2L,3L,4L,5L};

//asList返回的是个固定大小。
List<Long> asList = Arrays.asList(arrayLong);

//如果要编辑 List 再如下 new 一个出来
List<Long> list = new ArrayList<>(Arrays.asList(arrayLong))

//数组 转 ArrayList
ArrayList<Long> list = new ArrayList<Long>(arrayLong.length);
Collections.addAll(list, arrayLong);
