![]() POJO is simply a class with only private fields and public getter/setter methods. You can use Jackson libraries, for binding JSON String into POJO ( Plain Old Java Object) instances. You can generate model from JSON automatically using online tools like this. Remember to import the library in the app Gradle file implementation ':gson:2.8.6' // or earlier versions Now you can parse using Gson library: MyModel model = omJson(jsonString, MyModel.class) ![]() Private ArrayList posts = new ArrayList() You have to call your variables as your JSON keys, or use if you want to use different names. ![]() Then the model is automatically filled in. Using this library you only need to create a model with the same JSON structure. JsonObject ciAttr = j.getJsonObject("ciAttributes") ListIterator l = jsonArray.listIterator() JsonArray jsonArray = jsonReader.readArray() JsonReader jsonReader = Json.createReader(new StringReader(response.readEntity(String.class))) Response response = request.get() // REST call These APIs actually follow the DOM/SAX parsing model of XML. With these two jars I am able to parse the json and use the values. You may want to download the implementation of that spec like javax.json. YourObject o = omJson(JSONString,yourObject.class) īut if one just want to parse a JSON string and get some values, (OR create a JSON string from scratch to send over wire) just use JaveEE jar which contains JsonReader, JsonArray, JsonObject etc. If one wants to create Java object from JSON and vice versa, use GSON or JACKSON third party jars etc. For the sake of the example lets assume you have a class Person with just a name. ![]()
