How to parse this Json structure in Java

Question

I have the following Json structure:

{
    "Response": ["2014", "2015"],
    "Error": false,
    "ErrorDetails": null
}

How can I parse the value inside response?

I usually use this code:

JSONArray arr = obj.getJSONArray("Response");
for (int i = 0; i < arr.length(); i++)
{
    String post_id = arr.getJSONObject(i).getString(???);
    ......
}

But I can't use getString in this case

Answer 1

您应该直接调用arr.getString（i） 。
