How to handle null json key when processing JSON Object in Java and Android

nulljson.java

//in my example im creating a json object from json array 
JSONObject object = jArr.getJSONObject(i);
//getting an JSONArray from JSONObject
JSONArray roleJSONArray = object.getJSONArray("roles");
                    
//This is where i check the null json object if "location" value comes null
//Step 1: check if its null using isNull
if(object.isNull("location")){
//override the key value from location to another value
 object.put("location", "N/A");
 }
                            

lol, the number of times I revise my own gist...hahaha
