Check if a particular JSON Object is available or not


java android json object

Anyway, I got the solution with some Googling:I re-framed it as,

 if (!jArray.getJSONObject(j).has("child2")) {  map.put("Second Value", "N.A"); } else {  map.put("Second Value", jArray.getJSONObject(j).getString("child2")); }

Creating the JSONObject getchild2 = jArray.getJSONObject(j).getJSONObject("child2"); was rather, unnecessary.

And this works, rather perfectly! Refer this for more details: Checking if exists subObject in JSON

Thanks everyone for the help!

java android json object 

getJSONObject("child2");

Will throw an exception if child2 does not exist. Try this instead:

getchild2 = jArray.getJSONObject(j).optJSONObject("child2");

That way you don't have to catch an exception if child2 doesn't exist and can instead check for null.

java android json object

Try this:

{"main1" : [{             "id":"1"               "child1" : "valueA",               "child2" : "valueB",               "child3" : "valueC",            }, {                "id":"2"                  "child1" : "value1",                 "child3"  : "value3",           }]}
