how to parse json object inside json object in java

Question

I'm trying to parse below JSON and looking for "zip-code" value "526262". I'm new to Java and struggling to get the zip-code value?

This is my JSON:

{
    "id": "6fffdfdf-8d04-4f4e-b746-20930671bd9c",
    "timestamp": "2017-07-21T03:51:27.329Z",
    "lang": "en",
    "result": {
        "source": "testsrc",
        "resolvedQuery": "testquery",
        "action": "test",
        "actionIncomplete": true,
        "parameters": {
            "zip-code": "526262"
        }
    }
}

And this is my Java code:

       String test= "{\n" +
            "\t\"id\": \"6fffdfdf-8d04-4f4e-b746-20930671bd9c\",\n" +
            "\t\"timestamp\": \"2017-07-21T03:51:27.329Z\",\n" +
            "\t\"lang\": \"en\",\n" +
            "\t\"result\": {\n" +
            "\t\t\"source\": \"testsrc\",\n" +
            "\t\t\"resolvedQuery\": \"testquery\",\n" +
            "\t\t\"action\": \"test\",\n" +
            "\t\t\"actionIncomplete\": true,\n" +
            "\t\t\"parameters\": {\n" +
            "\t\t\t\"zip-code\": \"526262\"\n" +
            "\t\t}\n" +
            "\t}\n" +
            "}";

JSONObject request = new JSONObject(test);
String zipCode = request.getJSONObject("result").get("parameters").toString();
System.out.println("zipCode is : " + zipCode);

But I'm getting below output:

zipCode is : {"zip-code":"526262"}

How to get zip-code value alone?

Can someone help how to get this value in java?

String zipCode = request.getJSONObject("result").get("parameters").get("zip-code").toString(); ? — Vlado Pandžić

You should use getJSONObject when getting parameters so that you can keep using the JSONObject API to dig deeper.

request.getJSONObject("result").getJSONObject("parameters").getString("zip-code");

request.getJSONObject("result").get("parameters").getString("zip_code")

will solve your problem. JSON objects are built to handle nesting.
