and this is

Answer 1

This is not a valid JSON format. Look here to see the format of a JSON object / array.

If you want to be able to read both values, create an array:

String jString = "[{\"CategoryId\":1},{\"CategoryId\":2}]";
JSONArray jArr = new JSONArray(jString);
for (int i = 0; i < jArr.length(); ++i) {
    int i = jArr.getJsonObject(i).getInt("CategoryId");
    // do something with i which is an int, not a String
}
