遍历CharSequence数组，将每个元素转换为字符串，并将转换后的元素添加到结果列表中

   public static void main(String[] args) {
        CharSequence[] charSeqArr =new CharSequence[3];
        charSeqArr[0]="a";
        charSeqArr[1]="b";
        charSeqArr[2]="c";
        List<String> result = Stream.of(charSeqArr)
                        .map(CharSequence::toString)
                        .collect(Collectors.toList());
        System.out.println(result);

    }
