besides using Collections to get a synchronized version of a `TreeMap`, another approach to get a output according to sorted key is to do the reverse using a helper class.
for example, using ObjectMapper
//set the ordering mapper.configure(SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS, true);then to get the output or transform to another object, using the `mapper`
//output mapper.writeValueAsString(pairs) //transform mapper.convertValue(pairs, Map.class)Published
