The provided Java code snippet begins with a getExtractedDataMap method that calls a setExtractedDataToMap method. This is confusing because Java conventions dictate that getters retrieve values and setters mutate them, making a getter that calls a setter unconventional. The setExtractedDataToMap method converts a PayloadDto object into a Map. The getExtractedDataMap method then simply acts as an unnecessary intermediary. The core issue is that these are two poorly named methods where a single, well-named method would suffice.A more significant problem is the conversion of a Java object into a Map, which is a code smell indicating discomfort with object-oriented principles. This conversion is not justified for serialization purposes, as Java has built-in serializers that handle this transparently. DTOs themselves are designed for easy data serialization. The author expresses confusion about the purpose of this code, echoing the sentiment of the developer who discovered it. The original developer also gave up trying to understand the workflow for which this code was intended.
