JSON file parsing in java

Question

Edited. Anyone know how to read the record in every new line. The below code can only read 1 sentence.

JSONParser parser = new JSONParser();
    try
    {
        Object obj = parser.parse(new FileReader("src/test.json"));
        JSONObject jsonObject = (JSONObject) obj;
        String name = (String) jsonObject.get("name");
        System.out.println(name);



    }

You can use any JSON parsing libs like [Jackson](http://www.mkyong.com/java/jackson-streaming-api-to-read-and-write-json/). — Santosh, Jun 18 '13 at 04:02
I followed the download here link and it is a zip file and add external library to eclipse but still have error after inserting import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; — user2483015, Jun 18 '13 at 04:33
please post your json file, thing is once you have got the jsonobject then you need to iterate/fetch from the object based on your json structure. — Sikorski, Jun 18 '13 at 14:50

You can use codehouse jackson

ObjectMapper mapper = new ObjectMapper();
BufferedReader br = new BufferedReader(new FileReader(tweets));
Map<String, Object> json_as_map = mapper.readValue(br, new TypeReference<Map<String, Object>>() {});

After that you can traverse your map or arraylist according to ur structure.

You have to add http://search.maven.org/remotecontent?filepath=org/codehaus/jackson/jackson-jaxrs/1.9.12/jackson-jaxrs-1.9.12.jar in your classpath. And then use JAVA Collection APIs to parse JSON. – Anurag Tripathi Jun 19 '13 at 07:12
