stances. The following code demonstrates how to create an object model from
scratch and access data within it.
The following code is an example of JSON processing using the object model API:
JsonObject objModel = Json.createObjectBuilder()
.add("student",Json.createObjectBuilder()
.add("id", "854963")
.add("name", "Louis Poyer")
.add("weight", 78.6)
.add("gender","M")
.add("contact",Json.createArrayBuilder()
.add(Json.createObjectBuilder()
.add("address","Rue 632"))
.add(Json.createObjectBuilder()
.add("phone","985-761-0")))
).build();
JsonObject student =
objModel.getJsonObject("student");
String name = student.getString("name");
JsonArray contact =
student.getJsonArray("contact");
String address =
contact.getJsonObject(0).getString("address");
String phone =
contact.getJsonObject(1).getString("phone"));
