List<String> 与String[]互转

 

    public static void main(String args[]) {
        List<String> aList =  new ArrayList<>();
        aList.add("111");
        aList.add("222");
        aList.add("333");
        String str[] = aList.toArray(new String[]{});
        List<String> bList = Arrays.asList(str);
        System.out.println(bList);
    }

[111, 222, 333]
