Parsing json more efficiently?

I have a JSON like

{
    "status":{
        "server":{"bool":true},
        "request":{"bool":true},
        "third_party":{"bool":true},
        "operation":{"bool":false,"int":-12,"str":"Not authenticated!"}
    },
    "response":{
        "count":3,
        "emails":["[email protected]","[email protected]","[email protected]"]
    }
}

Note: The JSON code above it's just an example and it may seem illogical.

The problem is I think it is not efficient to parse it using JSONObject and the code becomes a mess.

Therefore, I would like to know whether there is a way to parse it like in PHP when using json_decode().

Which will make me reach the elements like in this way

JSONParser jp = new JSONParser(json);
boolean server_status = jp.status.server.bool;

I wish you can understand what do I mean and help me as well.

Thank you.

There are quite a few alternatives out there for parsing/writing JSON in java. Here are some pointers:

  1. http://jackson.codehaus.org/ This is a very complete solution which also has a StAX like API for super high processing speed.

  2. https://code.google.com/p/google-gson/ Also very complete

  3. https://code.google.com/p/json-simple/ If you need something simple that simply decodes everything to maps then you are right here.

If you want to navigate that JSON, the best library for this is, imho, Jackson. Combined with a library of mine, which has JSON Pointer support, you can do such things as:

final JsonNode node = JsonLoader.fromFile(...); // or .fromReader(), .fromString() etc
final JsonNode emails = JsonPointer.of("response", "emails")
    .get(node);
// etc

JsonNode is ultra powerful for navigating JSON.
