Android Java JSON parsing issue - missing attributes

I am just parsing one JSON file in Android and my JSON is not consistent, meaning that some attributes and values are missing so I get null pointer exception. I have understood that we should check before extracting value of each attribute if he actually exists:

JSONObject object = jsonArray.getJSONObject(i);
if(!object.isNull("name"))
   String name = object.getString("name");

Since I have 12 parameters to extract the code does not looks nice.

Is there any more elegant solution?

use `object.optString("name")`, you dont have need for check isNull. – KuLdip PaTel Mar 22 '18 at 10:41
KuLdip PaTel .optString("name", ""); was exactly what I was looking for, thanks! – junior Mar 22 '18 at 10:50
