Moshi.nextAdapter(). Encoding JSON in Java. Pretty print JSON. On decoding, the default concrete class of java.util.List is org.json.simple.JSONArray and the default concrete class of java.util.Map is org.json.simple.JSONObject. . We'll use the following Car class with two fields as the object to serialize or transformation automatically. Note that you can also use Javas transient keyword or Kotlin's @Transient annotation on these fields classes: Note: The Kotlin examples of this README assume use of either Kotlin code gen or KotlinJsonAdapterFactory for reflection. It is so confusing. Hi Green,Player is a Bean/Pojo class containing Java Objects based on which JSON to JavaObjects [and vice versa] takes place.This class will contain all the headers/root objects for your JSON.JSON for Players:{"NAME":"AD","ID":0001}Java Class for Players:{String NAME;int ID;----set getters and setters for these variables}Hope this helps. Conversely, the method annotated with @ToJson does not have to produce a String. The factory either returns an adapter to use, or null if it doesn't apply to the Refer to the Moshi JavaDoc for details on the various methods.

I'd instead return {value: JSON.parse(str), valid: true}; and in the catch block return {value: str, valid: false};.. and I'd change the function name to tryParse(). When reading JSON that is missing a field, Moshi relies on the Java or Kotlin or Android runtime to assign In my case I didn't want any dependancies.

Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of. Gson way for a bit more complex maps and lists using TypeToken.getParameterized method: We get the Type using the above mentioned getParameterized method like this: And then use the Gson object fromJson method like this using the mapOfList object like this: The mentioned object NewFile looks like this: You can use Gson. JsonPath also has functions that we can use at the end of a path to synthesize that path's output expressions: min(), max(), avg(), stddev() and length(). http://stleary.github.io/JSON-java/index.html.

" Gson is a Java library that can be used to convert Java Objects into their JSON representation. Using Java 8 you can get JSON as a string this simple: function. :) (and has a super low memory, direct from bytes mode with UTF-8 encoding on the fly).
