}Usage
Creating an empty JSONObject
JSONObject project = new Json().object().toJson();Creating a JSONObject with one string property
JSONObject project = new Json().object(o -> o.string("name", "molten-json"));Creating an empty JSONArray
JSONArray keywords = new Json().array().toJson();Creating a JSONArray with one string element
JSONArray keywords = new Json().array(a -> a.strings("json"))Creating a JSONArray with multiple string elements
JSONArray keywords = new Json().array(a -> a.strings("json", "java-8", "fluent", "dsl"))Creating a JSON string
String project = new Json().object(o -> o.string("name", "molten-json")).toString();Creating a pretty-printed JSON string
String project = new Json().object(o -> o.string("name", "molten-json")).toPrettyString();Creating a nested JSONObject
JSONObject project = new Json()
.object(o -> o
.string("name", "molten-json")
.string("version", "0.1.0"))
.object("repository", r -> r
.string("type", "git")
.string("url", "https://github.com/helpermethod/molten-json")))
.toJson(); Ignoring properties with null values
String version = null;
JSONObject project = new Json(NullHandlingStrategy.IGNORE_NULL)
.object(o -> o
.string("name", "molten-json")
.string("version", version))
.toJson();
