json-simple 사용법

의존성 추가

dependencies {
    implementation 'com.googlecode.json-simple:json-simple:1.1.1'
}

생성

JSONObject obj = new JSONObject();
obj.put("name", "skyer9.pe.kr");
obj.put("age", 2019);

JSONArray list = new JSONArray();
list.add("messages01");
list.add("messages02");
list.add("messages03");

obj.put("messages", list);

System.out.println(obj.toJSONString());

문자열에서 json 파싱

String resultJson = "{\"results\":[{\"itemid\":1990508},{\"itemid\":2017283}]}";
JSONParser parser = new JSONParser();
JSONObject jsonObj = (JSONObject) parser.parse(resultJson);

JSONArray results = (JSONArray) jsonObj.get("results");

System.out.println(results.toJSONString());

```
