在Java中，如何从子数组中的值提取json数组的子集？

Question

Following is my json :

{
    "id": null,
    "extId": "720916740",
    "legacyId": null,
    "customerId": null,
    "accountId": null,
    "clientId": null,
    "publisherId": null,
    "name": "AllColumns1_1482141239819",
    "status": "ACTIVE",
    "operationStatus": null,
    "startDate": "20180101",
    "endDate": null,
    "channel": "SEARCH",
    "lastSyncDate": null,
    "linkStatus": "NOT_LINKED"
  },
  {
    "id": null,
    "extId": "720916743",
    "legacyId": null,
    "customerId": null,
    "accountId": null,
    "clientId": null,
    "publisherId": null,
    "name": "AllColumns2_1482141239819",
    "status": "ACTIVE",
    "operationStatus": null,
    "startDate": "20180101",
    "endDate": null,
    "channel": "SEARCH",
    "lastSyncDate": null,
    "linkStatus": "NOT_LINKED"
  },
  {
    "id": null,
    "extId": "720933833",
    "legacyId": null,
    "customerId": null,
    "accountId": null,
    "clientId": null,
    "publisherId": null,
    "name": "2TestCamp2_1482149078243",
    "status": "ACTIVE",
    "operationStatus": null,
    "startDate": "20180101",
    "endDate": null,
    "channel": "SEARCH",
    "lastSyncDate": null,
    "linkStatus": "NOT_LINKED"
  }

From above json, I want to get id and extid of where name is "2TestCamp2_1482149078243". How can I get this in JAVA ?

In general, From a json array, first I want to find that sub-array, where value is "2TestCamp2_1482149078243"; and then from that sub-array, get values of keys id and ext id.

Thanks. Would be great if someone helps me in this. I am new to java and json.

String validate_name="2TestCamp2_1482149078243";

JSONObject object = new JSONObject(YOUR-JSON-Object);
JSONArray getArray = object.getJSONArray("Result");

for(JSONObject value:getArray)  //For Each loop to iterate the Objects from JSONArray
{
    if(value.getString("name").equals(validate_name))
    {
        value.getString("id");
        value.getString("extId");
    }
}
