Answer 1

Parameter you are sending is JsonArray and referring to JsonObject. The Correct way is

JSONObject jsonObj = new JSONObject("{'id':['5','6']},{'Tech':['Java']}");      
    System.out.println(jsonObj.getString("id"));

    JSONArray jsonArray = new JSONArray("[{'id':['5','6','7','8']},{'Tech':['Java']}]");
    System.out.println(jsonArray.length());
    for(int i=0;i
