Answer 1

First convert your json to POJO using online converter http://www.jsonschema2pojo.org/

Then in Java use below code change getString('yourkeyValue') keys as per JSON pojo

public void onSuccess(Object result) {
                try {
                    JSONObject jsonObject = new JSONObject(new JSONTokener(result.toString()).nextValue().toString());
                    if (jsonObject.getString("responseCode").equals("00")) {
                        JSONObject jresponseData = new JSONObject(jsonObject.getString("responseData"));

                        if (jresponseData.has("Table1")) {
                            JSONArray jsonArray = new JSONArray(jresponseData.getString("Table1"));
                            for (int i = 0; i < jsonArray.length(); i++) {

                                JSONObject jsonObject1 = jsonArray.getJSONObject(i);

                                MyPojo listObj = new MyPojo();

                                String sName = StringUtils.defaultIfEmpty(jsonObject1.getString("s_Name"), "").replace("null", "");
                                String s_desc = StringUtils.defaultIfEmpty(jsonObject1.getString("s_About"), "").replace("null", "");
                                String simgUrl = StringUtils.defaultIfEmpty(jsonObject1.getString("Image").replace("@", ""), "");
                                String pk_id = StringUtils.defaultIfEmpty(jsonObject1.getString("PK_ID"), "0");

                                listObj.setChannelName(sName);
                                listObj.setS_shortDes(s_desc);
                            }

                        }

                    }
                }
            }

There are multiple ways you can get it from the server using Rxjava and retrofit and volly, - Refer this link to how to use retrofit https://www.androidhive.info/2016/05/android-working-with-retrofit-http-library/

• you can use DTO generator plugin in the android studio to generate the getters and setters from JSON.

• or else you can use http://pojo.sodhanalibrary.com/ link to generate the getters and setters
