java - 将 ArrayList 序列化为 String 并将 String 反序列化为 ArrayList 约束是数组列表包含字符集中的任何字符

Question

我在下面的代码中进行序列化，并更正序列化和反序列化的代码，如何做到这一点？我们不需要任何分割定界符，因为列表可能包含任何字符，因此不可能进行字符串分割

 public class ArratListSerializaationTest {

        public static void main(String[] args) {
            List<String> dataList = new ArrayList<>();
            dataList.add("A");
            dataList.add(",");
            dataList.add("B");
            String datStr = serialize(dataList);
            List<String> receivedList = deserialize(datStr);
        }

        public static String serialize(List<String> dataList){

            StringBuilder dataBuilder = new StringBuilder("[");
            dataList.forEach((data) -> {
                dataBuilder.append(data);
            });
            return dataBuilder.append("]").toString();
        }

        public static List<String> deserialize(String dataStr){

             ArrayList<String> dataList = new ArrayList<>();      
             //TODO
            return dataList;
        }
    }

最后我给出了这样的解决方案，这样我的问题就解决了
