Deserializer Json with Gson in java

Question

I want to parse data from Json with GSon in java I have this json

    {
      "time": 3.251,
      "about_us": {
        "dc:identifier": "some string",
        "dc:title": "some string",
        "dc:contributor": [
          "1",
          "2"
        ],
        "dc:hasversion": "some string"
      },
      "results": {
        "ocw": [
          {
            "title": "some string",
            "url": "some string",
            "language": "some string",
            "university_name": "some string",
            "university_url": "some string",
            "description": "",
            "uri": "some string5",
            "similar": "some string",
            "resourceType": "OCW",
            "relatedoers": [

                    ]
          }
        ],
        "otheroer": [

        ]
      }
    }

I only need to get the "ocw" field, I am confused how to do this. I created corresponding java classes for the json objects and use @SerializedName annotations to specify the field name to grab for each data member.

The classes are as follows.

Results

Ocw

What research have you found on this so far or what code you have tried? There should be lots of examples for this out there. — mdnghtblue, Nov 22 '14 at 21:10

If you have this json stored in some jsonString:

    JsonObject jsonObject = (JsonObject) new JsonParser().parse(jsonString);
    JsonElement jsonElement = jsonObject.getAsJsonObject("results").getAsJsonArray("ocw").get(0);
    MyObject object = new GsonBuilder().create().fromJson(jsonElement, MyObject.class);

MyObject should reflect this part:

        "title": "some string",
        "url": "some string",
        "language": "some string",
        "university_name": "some string",
        "university_url": "some string",
        "description": "",
        "uri": "some string5",
        "similar": "some string",
        "resourceType": "OCW",
        "relatedoers": [

                ]
