I want to return a boolean value to check if the String contains any 'value' or not after getting data from database. It should return true if it contains anything else false.
JSONObject context = memory.getContext(senderId, sessionId);
If this context contains any value from db, it should return true when i sysout it. Thanks in advance for your help.
I am using org.json.simple library
Just check if the context is null
or not and return if size()
is grater than 0
.
...
JSONObject context = memory.getContext(senderId, sessionId);
return context != null && context.size() > 0;
由于JSONObject
是org.json.simple.JSONObject
它的size
方法将使您确定它是否具有任何内容,例如:
return context != null && context.size() > 0;
