JSON BINDING 1.0 – SAMPLE Hero hero = new Hero(); hero.setName(“Jason”); hero.setAge(25); hero.setAffiliation(“Argonauts”); Jsonb jsonb = JsonbBuilder.create(); jsonb.toJson(hero) { “name”: “Jason”, “age”: 25, “affiliation”: “Argonauts” } 10 What’s new in Java EE

JSON PROCESSING 1.1 Integrate emerging IETF standards like: JSON Pointer, JSON Patch & JSON Merge Patch Support Java 8 streaming API Allow parsing big JSON 11 What’s new in Java EE

JSON PROCESSING 1.1 – SAMPLE [ [ { { “op”: “replace”, “path”: “/0/age”, “value”: 28 “name”: “Jason”, “age”: 25, “affiliation”: “Argonauts” } ] } ] new JsonPatch(patch).apply(heroes); new JsonPatchBuilder().replace(“/0/age”, 28).apply(heroes); 12 What’s new in Java EE
