How, when reading a json file from index.php, how to create an array of strings that will be used in another class?

Question

Java

Here is the code to create an array. How to use in another class? When using heteros and seters: in another class, it says that it is necessary to make the nested class static. How to be? Tell me please

try {
                    JSONObject jsonObj = new JSONObject(jsonStr);

                    // Getting JSON Array node
                    JSONArray items = jsonObj.getJSONArray("items");

                    // looping through All Contacts
                    for (int i = 0; i < items.length(); i++) {
                        JSONObject c = items.getJSONObject(i);

                        String latitude = c.getString("latitude");
                        String longitude = c.getString("longitude");
                        String[] coo = new String[items.length()];
                        coo[i] = "" + latitude + "," + longitude + "";
                                            }
                } catch (final JSONException e) {
