The map object's iteration ordering is based on the order in which name/value pairs are added to the corresponding builder or the order in which name/value pairs appear in the corresponding stream. Author: Jitendra Kotamraju Nested Class Summary ...
<strong>Warning:</strong> this class represents null in two incompatible ways: the standard Javanullreference, and the sentinel valueJSONObject#NULL. In particular, callingput(name, null)removes the named entry from the object butput(name, JSONObject.NULL)stores an entry whose value isJSONObject...
