I am using minimal-json-0.9.5.jar in my javacode. I am retrieving the json from API in java and process it. ObObj.get("subObligations").asArray() gives NullPointerException error.

JsonArray SubObArr1=ObObj.get("subObligations").asArray();

ObObj contains array "subobligations" with small letter. The content has both subobligations and subObligations.

ObObj.get("subObligations").isNull() is not helpful. this also gives same error. how to handle the jsonobject when it does have not key.

Basically, use `== null` to check for a null reference... – Jon Skeet May 20 '22 at 10:46
@JonSkeet It did work. I always thinking about checking with IsNull and missed to use ==null. Thanks for the answer. – user3493803 May 20 '22 at 10:52
