How to compare null value from the JsonObject in java

Question

stackoverflow member i need some help from you.

I am having a JsonObject given below

{
\"Id\": null,
\"Name\": \"New Task\",
\"StartDate\": \"2010-03         


        

Answer 1

These two methods works

if( jsonObject.get("parentId").equals(null) )

if( jsonObject.isNull("parentId") )

Because the JSONObject has its own Null class, so java primitive null is not same as Null() in JSONObject.
