How to check if a json key exists?

Question

So, I get some JSON values from the server but I don\'t know if there will be a particular field or not.

So like:

{ \"regatta_name\":\"ProbaRegatta\"

JSONObject class has a method named "has":

Returns true if this object has a mapping for name. The mapping may be NULL.
