Not Work ?

We want to query the backend for a list of episodes of the TV show "Doctor Who". Start by declaring a ParseQuery variable named query and initialize it with a ParseQuery constructor. Use "DoctorWhoEpisodes" as the class name and ParseObject as the type (remember that ParseQuery is a generic class that must specify a type).

La respuesta es esta :

ParseQuery<ParseObject> query = new ParseQuery("DoctorWhoEpisodes");

pero no funciona !

I think you need to have the type of query inside <> because ParseQuery is generic. So something like:

ParseQuery<String> query = new ParseQuery<String>("DoctorWhoEpisodes");

This may help, but If you can tell me which code challenge it is I will have a look at it properly.


Oh , Tienes mucha razón . Gracias !!
